CenterONE® Software

Overview The purpose of this tutorial is to describe the CenterONE software features and functionality that make it a valuable tool in the hands of customers who desire to create their own motor control centers (MCCs).

CenterONE software is the first MCC software created for customers, engineering firms, and sales and distribution staff.

C enterONE is part of the growing, interactive family of Windows-based software from Rockwell Automation. CenterONE software simplifies the process of configuring motor control centers via dialog tabs for overall MCC setup. The CenterONE software has configuring capability that places it well ahead of any previous MCC software tool.

CenterONE software was designed to:

• be easy to use, even for infrequent users and MCC novices• speed up the design process by automating and linking the steps• reduce errors (ensure that it is possible to build the MCC as specified)• provide detailed reports and data through laser printers and

AutoCAD systems• provide plant standards for MCCs (via user-controlled standard settings)

Installing CenterONE Software from the Product Selection Toolbox CD

1. Start Windows.

NOTE: If CenterONE software has already been installed on this computer, skip to the TIP following this section on Installing CenterONE software, and then go on to the Starting CenterONE software section.

2. Insert the CD into the CD-ROM drive.

3. At the CD drive, open the CenterONE folder.

4. Within the CenterONE folder, click on the file setup.exe to start the installation.

5. Follow the on-screen instructions to complete your installation. Where decisions are required, it is best to select the suggested default.


2 CenterONE® Software

Starting CenterONE 1. Under the Start Menu, you may go to Programs/Rockwell Automation/CenterONE. The CenterONE Install Shield may have installed a Start CenterONE shortcut on your desktop, and you may also double click on the icon.

2. The following selection screen will start up next. Click on Launch CenterONE software and a blank Windows screen will appear

3. To start a new workup, select the New icon or choose File from the menu and select New. Choose Create a new MCC Workup.

TIP The exercises created for this lab are cumulative. Therefore, each section must be completed thoroughly and accurately before advancing to ensure desired outcome.


CenterONE® Software 3

Configuring an MCC 1. The Start Workup screen will appear. The button next to “Create a new MCC Workup” should already be selected. If it is not, select it and click OK.

The MCC setup sheet window appears as shown below. This window is used to apply the general MCC specifications and enter order information. There are also tabs for unit specifications so that the user does not have to re-enter the same options for each unit required.

NOTE: Use the mouse or tab key to move within fields in a window.



.

TIP If OK is clicked or the user hits enter before finishing all required tabs, error checking begins. If a required tab is not complete, it may be opened and an error message will appear, indicating that the required data has not been specified. If this happens, find that tab on the following pages 5 through 13 and enter required data in the designated fields:

After entering the information, return to the tab that was being worked on before error checking was triggered.

TIP If all the required data tabs were completed properly and you select OK, Apply, or enter, CenterONE will assume that you have finished entering the MCC setup. If you accidentally close the MCC Setup window and its 13 tabs, reopen it by selecting Specify, then Setup from the toolbar.

TIP An AutoSave window may appear while completing the lab exercises, suggesting you save your work. Click OK to continue. You may be prompted to name the .C1 file. It is a good idea to save your MCC workups frequently while creating them.

TIP As subsequent versions of CenterONE software are created, minor differences in the appearance of units, such as their sizes, may be evident. The diagrams on your computer might not always match the diagrams in this manual. The differences do not necessarily indicate an error.



Customer Information

1. Click on the Customer Information tab if it is not already displayed.

NOTE: The information entered here will show up in strategic places on documents and drawings to help identify this workup for later use.

2. Enter the following setup instructions on the MCC Setup Sheet in the designated fields:

• Project: Acme Manufacturing

• MCC Name: Cooling System MCC

• Equipment Type: Sections with Units Installed

• Standards: United States

NOTE: Making this choice alerts configuring software to edit based on U.S. codes and standards.

For this lab, optional information fields will be left blank.



Wiring and Enclosure

1. Click on the Wiring and Enclosure tab.

2. Enter the following setup instructions in the designated fields:

For Class 1 Wiring Type, enter B-T Control and Power Terminal Blocks.

NOTE: This will specify the wiring type that will be used on all units in the MCC.

Wiring diagrams for each unit can be located in a pocket inside the unit or can be collected and centrally stored in the bottom of one of the sections. One exception to this would be if there is no room to store documents, such as in a 0.5 space factor (SF) unit. If there are 0.5 SF units in the workup, then select either centrally located or inside each unit AND centralized. The latter description means that for units 1.0 SF or larger, the wiring diagrams will be stored in the unit, while all wiring diagrams for 0.5 SF units will be stored in a centralized location.

For Diagram Location, select Wiring Diagram within Each Unit.

CENTERLINE MCCs are available in two heights — 71 in. and 90 in. Select the 90 in. height.

MCCs can be ordered in back-to-back configurations when they are to stand as an island in the middle of the floor. Typically, MCCs are mounted with their backs to the wall.



For Mounting Design, enter Front Mounted, 15” Deep.

There are a number of different enclosure types that can be specified. These are all assigned a NEMA designation:

• NEMA 1 can be used for atmospherically controlled areas.• NEMA 1G has gasket material around the doors of the units but no

gasketing around wireways or between MCC sections.• NEMA 12 is fully gasketed to prevent ingress of dust.

For Enclosure Type, enter 12—Fully Gasketed with Bottom Plates.

Ignore the Space Heaters and Mounting Channel fields at the bottom of the screen for this lab exercise.



Incoming Power

1. Click on the Incoming Power tab.

2. Leave the Line Voltage at the default setting, 480 Volts/60 Hertz. (If desired, click on the drop down menu to see all the combinations available.)

Available Fault Current is the maximum current that could possibly flow through this MCC in the case of fault. In most cases, this fault is directly related to the characteristics of the transformer that is supplying this MCC.

3. On the Incoming Power tab, enter 27000 as the Available Fault Current in the designated fields.

Main Bus Bracing represents the maximum current that the power busses in the MCC can withstand without physical damage. During the short period of a fault, tremendous magnetic forces are experienced by the MCC. An MCC with an insufficient bus bracing will sustain damage during a fault that might require replacement of some or all of the equipment. Note that the values of the Main Bus Bracing and Available Fault Current constitute a “belt-and-suspenders” approach to specifying the correct bus.

When specifying a bus bracing strength, choose the next highest withstand rating above the available fault current. The minimum bus bracing of 42,000 Amperes will suffice for a fault current of 27,000 A.

For Main Bus Bracing, enter 42kA (rms symmetrical).

IMPORTANT The Available Fault Current should not be guessed. Transformers have a maximum current they can deliver.



The MCC Connection Type allows the user to specify how the MCC is connected to the line power. If a disconnect is desired, it can be either a fused or circuit breaker type. If another disconnecting means is nearby, the power cables may be landed directly on incoming lugs without a disconnect. If this MCC is an addition to an existing MCC, the bus bars will be spliced together and the termination of incoming lines does not need to be specified. In this exercise, a circuit breaker will be specified for the main disconnect.

For MCC Connection Type, enter Main Circuit Breaker.

NOTE: No neutral bus (for four-wire systems) will be specified in this lab.

Bus Work

1. Click on the Bus Work tab.

The Main Bus is the horizontal bus that runs through the middle of all MCC sections to distribute power. Inside each section there is a vertical bus that distributes power to all the units within one section.

The Main Bus Rating is a measure of the full load capacity of the horizontal bus under normal operating conditions. This is different from the fault capacity entered earlier.

2. Click on the pull-down menu to reveal standard Ampere capacities available.

3. Enter 800A for the Main Bus Rating in the designated fields within the Bus Work tab.



The Main Bus Material can be either aluminum or copper. Aluminum is available only in 600 and 800 Amp capacities. The aluminum is tin plated to prevent oxidation. Copper is available in all capacities and can be plated with tin or silver. Tin plating is less expensive and superior to silver in most ways. However, some older specifications still require silver plating on the bus. The material and plating specified for the main (horizontal) bus will be used for the vertical buses also.

For the Main Bus Material, enter Copper/Tin Plated.

The Underwriters Laboratories listing requires a ground bus be present in the MCC. If equipment grounded at the MCC is desired, ground wires can be attached directly to this bus.

For Horizontal Ground Bus Size, enter 1/4” x 1”.

The ground bus can be copper or tin-plated copper. Accept the unplated copper default.

For Horizontal Ground Bus Loc., enter Bottom.

The vertical unit ground bus connects the chassis of a plug-in unit to the MCC ground before the power is connected to the bus stabs. The standard vertical ground bus is zinc plated steel; however, unplated copper or tin plated copper may be specified.

For Vertical Ground Bus, select Plug-in Zinc-Plated Steel.

Specifications Miscellaneous MCC Specs

1. Click on the Misc. MCC Specs tab.



One of the safety features on CENTERLINE motor control centers is the option of “automatic shutters.” These louvers cover the openings to the vertical bus bars to protect operators from contacting live electrical conductors. Automatic shutters, as the name implies, open automatically when the unit is inserted into the section. Other options include manual shutters, replaceable caps, or no covers at all.

2. Enter the following MCC options in the designated fields.

For Stab Opening Protection, enter Automatic Shutters.

In this lab exercise, do not select any of the other Miscellaneous Options on this tab, except for the Master Nameplate.

A Master Name Plate is an engraved plaque that describes the MCC. This nameplate usually is located on the top wireway cover of the second section of the MCC. There can be up to five (5) lines of text on the nameplate.

For Number of Lines, enter 3.

Choose a number of text lines for the nameplate, then enter appropriate text in the blank fields. In our example, we used

Line 1: This is Line 1



The main structure information is complete. Unit information may be entered now. If all (or most) of the units will have similar options, those options can be specified within the following two tabs (Unit Specifications and Common Unit Options).



Unit Specifications

1. Click on the Unit Specifications tab.

The data on this page is used for any new units created after the information is entered. It is possible to set a certain group of general unit options, enter all the units with those options, and then go back and change the general options. Units created after the change would have the new option’s characteristics. Units created before the change would be unaffected.

The choices for the type of disconnects are fused disconnects or circuit breaker disconnects. Select the type of disconnects for units.

2. Enter the following setup instructions in the designated fields.

For Disconnect Type, enter Circuit Breaker.

In addition to having a Master Nameplate for the whole MCC, individual nameplates are available for the door of each unit. The standard nameplate is a cardholder similar to what is often seen on the face of file drawers. Custom engraved nameplates can be ordered in a variety of options.

For Nameplate Type, enter Cardholder.

Rockwell Automation offers a wide variety of overload protection for motors. Protection can include anything from the simplest eutectic thermal overloads to the latest solid state overload relays with built-in DeviceNet.

Note that several options may seem incomplete, such as eutectic overloads without heaters or provision for SMP-1 or 2. At the MCC ordering stage, it is



often difficult to determine the exact size the overload should be. Different brands or types of motors with the same horsepower rating can have varying full load or inrush current characteristics. Therefore, the final decision on overloads may be delayed until the MCC is delivered and the actual motor data is known.

Current ranges on electronic overloads can be adjusted (or programmed) in the field. These overloads (SMP and E3) usually may be specified to cover a wide variety of motors. Therefore, SMPs and E3s may be ordered before the final motor data is known.

For Overload Relay, enter E3 Plus (E3 Plus solid state overload relay). Also, make sure that the “External Reset Button” box is not checked.

Separate control or common control is available for the control circuit power. A higher capacity transformer is available if unit heaters, extra pilot lights, or other control-power-consuming devices require additional power.

For Control Type, enter Transformer with Secondary Fuse (transformer control type with a standard capacity transformer and primary fuse protection for the transformer).

For Control Wiring, enter #16 AWG Cu, Type MTW.

The ground stab is the part of the plug-in unit that grounds the unit chassis. The plug-in ground stab is a first-make, last-break design. A heavier design (solid copper stab) is available.

For Ground Stab, enter Copper Alloy (standard).



Common Unit Options

1. Click on the Common Unit Options tab.

There are ten (10) option categories to choose from. At this point no specific units (e.g. starters, drives, or feeders) have been specified. CenterONE software will use the information on this page to pre-load options when units are being specified. CenterONE software will also put the appropriate option on the units. For example, PLC-specific options will not be applied to starters and vice-versa.

Notice that of the ten option categories, only “Relays” appears bold when this window is first viewed. As options are specified in the different categories, the categories will show up as bold to indicate to the user that an option has been chosen in this category.

Why is “Relays” bold when no options have been specified? By choosing the E-3 solid state overload relay on the previous tab, certain relay options have already been specified. If the eutectic overload had been chosen, this category would not appear in bold type.

One normally open (N. O.) auxiliary contact is supplied on a standard starter. This contact is used as the hold-in for the starter. The E3 has inputs to



monitor the status of contacts as well. Therefore, a second N.O. contact will be added to the contactor to provide feedback to the E3.

1. Click on the “Auxiliary Contacts” button from the Common Unit Options tab.

2. Click on Starter or Contactor Mounted Auxiliary Contact in the option window.

3. Click on Add Auxiliary Contacts on Starter/Contactor to add an auxiliary contact on a starter.



Notice the “Aux Contact” button appears in the lower right corner of the window. Use this button to configure the number and type of auxiliary contacts to be added.

4. Click Aux Contact.

5. Select 1 from the drop down menu in the Normally Open Quantity—External field. The External/Internal descriptions for auxiliary contacts are for circuit breaker auxiliaries. Click OK.

Notice that the “Auxiliary Contacts” heading is now bold like the “Relays” heading. Any starter or contactor unit that is added to the lineup from this point on will have an additional N.O. contact on the relay.

It is also possible to put a contact on the disconnect switch, either on the circuit breaker or the fusible disconnect. Earlier it was specified that circuit breaker disconnects will be used. Circuit breaker disconnects can be either auxiliary contact mounted internal to the breaker or externally on the disconnect mechanism.



6. Select Disconnect or Circuit Breaker Mounted Auxiliary Contact from the Options window.

7. Select Add Auxiliary Contacts Disconnect/Breaker Mounted from the SELECTION window.

8. Click the Aux. Contacts button in lower right corner. This time choose 1 N.O. in the Normally Open Quantity—Internal field (for the disconnect).

9. Click OK.

The last unit option that will be chosen for all units is push buttons and selector switches.

10. Click the button next to “Pilot Devices.” In the OPTION window, scroll down and click Push Buttons and Selector Switch.



11. Under “SELECTION,” choose the second option—Hand-Start, Hand-Stop, Hand-Off-Auto (1F for FVNR Only). (FVLC is a full voltage lighting contactor and FVNR is a full voltage non-reversing starter.)

This completes the unit options to be specified at this time. Note that it is possible to change options when the individual units are specified. No units have been specified yet; only “global” options have been set for a time when units are specified. Feel free to click on the other buttons to see what other options are available in each category. Click on various choices in the OPTIONS window, but do not click on any choices in the SELECTIONS window; doing so will add these selections to the global options. If you accidentally do click a selection, click it again to de-select it.

12. Click Apply.

Because circuit breakers were specified for all units and internal auxiliary contacts were specified for all breakers, the following screen will appear.

Answer No to this question to save costs on units without control circuits

AutoCAD

The next two tabs, AutoCAD© and MCC User Notes, allow the user to provide information that will appear in specific fields of the main MCC structure drawing. The drawings will not be printed in this lab. Leave these fields blank.



DeviceNet Information

1. Click on the DeviceNet Information tab.

2. Click the box next to Built-in DeviceNet Cabling.

Built-in DeviceNet cabling means that the DeviceNet cable is run behind the vertical wireway. There are six ports in each wireway to plug in DeviceNet units.

3. Click the box next to IntelliCENTER Software.

Entering a check mark in the IntelliCENTER Software box will supply the software with the MCC. The other fields are accepted at their default values.

The warning window below will appear to ask if you need a copy of the IntelliCENTER software. Click Yes.

A number 1 will automatically fill the space next to Software CD.

4. Enter 1 for “Network No.” and 500 KB for “Baud Rt.”

The last three tabs, “IntelliCENTER Shipping Information” and “IntelliCENTER Software Registration” (for the software CDs) and “Structure Modifications,” are not used in this lab exercise.



5. Click OK at the bottom of the MCC Setup Sheet window.

6. Click OK to close the “What’s Next?” window.

NOTE: The button is in the tool bar. If changes or corrections to the MCC setup unit options are needed, click this icon.

Adding New Units

Once you have specified the main options for the MCC sections and MCC units, you are ready to begin specifying individual units. For the purpose of this lab, unit selections will be kept simple, although CenterONE software will allow many different types of units to be specified in a real-life example.

TIP Have you saved your workup yet? Now is a good time to do that. If this is the first time you are saving, give the workup a name (like “CoolingSystemMCC.C1” for example) and save it.

Note that unless you specify otherwise, your workups will be saved into a CenterONE workups folder that will be created in your My Documents location on the computer.



Specifying Units

Once the MCC setup is complete, units may be specified. Three windows associated with our MCC (Cooling System) appear:

• Layout• Spreadsheet• Unit

1. Click on the header of each window to view the contents of each page. Notice that there is no information on any of the three windows. That is because no units have been added yet.

2. At the Unit: Cooling System MCC window, click New. The “Add New Unit” window appears.

This window allows the user to select the type of unit to be added to the MCC line. Notice that there is a message flashing at the top of the window: “Main Device not Selected.” It is good practice to specify the main disconnect unit first.



3. Click the button next to “Mains” and click OK. The “Step 2 of 2” window for specifying mains appears.

In the first section of this window, “Unit Type,” the user is asked to specify a type of main unit. Remember that when the incoming power was specified, “Main Circuit Breaker” was specified.

Enter the following data in the designated fields.

For Unit Type, enter Main 3-Pole Circuit Breaker.

The Frame Rating for the breaker already has been chosen to match the 800A bus capacity that was specified earlier. Verify that the Frame Rating is 800A.

For Trip Current, enter 800A.

For Lugs for Incoming Lines, enter Standard (default setting).

An incoming main is not a plug-in unit. The connections from the main to the horizontal bus must be able to carry the full-rated amperage of the MCC. Therefore, main disconnects bolt directly to the horizontal bus. Since the main cannot be moved, its position in the MCC (actually in the section) must be specified. Specify top or bottom by clicking the appropriate button. There is no additional charge for either location.

For Mounting, enter Top.

4. Click OK to accept the new main circuit breaker.

5. Click OK to close the message window.

The Unit window, which was previously blank, now contains information about the main. Notice that at the top of the window there is a unit ID number



and description. If the main was created as the first unit, it should have an ID number of 1. The description is “MCB.” The complete description of the MCB is shown at the bottom of the Unit window.

6. Click on the other two windows that are open (Layout and Spreadsheet). Notice that there is now information about this first unit on all three windows.

7. Go back to the Unit window to add more units.

8. Click on New, then select Contactors and Starters (but not IEC) and click OK. Choose FVNR (Full Voltage Non-Reversing) starter from the pull down menu.

9. Enter the following information in the designated fields.

For Qty., enter 11.


For Horsepower, enter 5 HP.

Eleven (11) of these FVNR units in the 5 HP size now will be created. The disconnect has defaulted to circuit breaker based on earlier input for global



unit specification, but it could be changed here. Make sure the quantity is 11.

10. Click OK.

There is now another unit on the Unit page.

11. Scroll down the page to view unit options. These should be the ones specified in the global options under MCC Setup.

12. Advance to the Spreadsheet and then to the Layout windows. Notice there are new entries on both pages.



Adding More Starters

1. Click on the Unit window.

2. Select New from the Unit window. Then select Contactors and Starters and click OK.

3. Select FVNR-Full Voltage Non-Reversing from the Unit Type window.

4. Choose four starters rated at 40 HP. Click OK.

5. Notice that the Unit window is now showing the 40 HP starter. Click the down arrow next to Unit ID. It is possible to view any of the units that have been entered so far by selecting the ID #.



Adding Drives

1. Just for variety, add a couple of drives and a few feeder breakers.

2. Select New. Click on Variable Frequency AC Drives and OK.

3. Select VFD—Variable Frequency AC Drive (PowerFlex 700) from the drop down menu.

4. Enter the setup instructions in the designated fields.

For Quantity, enter 4.


For Horsepower, enter 25 HP.

For I/O Control Voltage, select 120V AC.

For Human Interface Module, enter LCD Display, Digital Keypad.

5. Click OK.

6. You will now be at the Unit view for the PowerFlex 700 drive units just created. Scroll to the bottom of that view to Options... and note that DeviceNet communications is not listed. We did not pre-select a communications option for these devices, but it is easy to add. Click on Options... and a Unit Options screen will appear

7. Click on the button next to AC Drives and then click on Communication Modules (VF AC Drives).

8. Select Add DeviceNet Communication Module mounted internally (-14GD).

9. Click OK. Note that the DeviceNet Communication Module mounted internally (-14GD) now is an option included on these four PowerFlex drive units.



Adding Feeder Circuit Breakers

1. Select New. Click on Feeders.

2. Click OK. Then click on FCB Feeder 3-Pole Circuit Breaker.

For Quantity, enter 5.

For Frame Rating, select 150A.

For Trip Current, enter 100A.

3. Click OK.

Laying Out Units in MCCs Once all the units in the MCC have been specified, the next step is to lay out the units inside the MCC.

1. Click on the Layout: Cooling System MCC window. Across the bottom of the window is a row of boxes (created in the previous exercises) that represents all the units in the MCC.

2. Scroll this window down to see the various sizes of the units. Note that some of the units and drives are very big.



Automatic Layout Units

This lab example MCC has only a few units and will have seven sections (as you will see very soon). The MCC layout will be done automatically and the front elevation will be shown. Each unit must be placed in a vertical section. It is possible to drag-and-drop each unit from the bottom of the screen into sections. CenterONE software has an Automatic Layout feature to simplify and speed up this process.

1. Click on Utilities from the main menu and select Auto Layout. A pop-up window will appear and prompt you to select which end of the MCC will receive the main (incoming) power.

2. Choose the leftmost section, then click OK. The MCC will be laid out automatically and the front elevation will be shown.

Click OK on the Automatic Layout Completed message box.

3. Once the auto layout is complete, it will be necessary to supply blank doors. Select Utilities from the main tool bar, then choose Fill in Blank Doors. The open (red) areas will be filled in.

NOTE: Keep this screen open for the next exercises. Save your workup.



Manually Adjusting Auto Layout

Suppose it was desired to spread out the load that occurs in section 6. Note that there are four 100 Amp feeders and two 30 HP starters. Let’s move one of the FCBs from section 6 to an open location in section 7.

1. Pull the blank door at the top of the line-up by clicking and dragging the door off to the side.

2. Next, click and drag the FCB in the top of the sixth section to the top of the seventh section. Note that it is not necessary to precisely locate the FCB. If the pointer is close enough, the unit will “snap” into place.

3. Now use the blank door to fill in the open space in section 6.

All the units in the MCC can be relocated in this manner. If an overload condition exists in one section, units in that section may be moved easily.

Final Edit of MCC Line-up

CenterONE software has a function that will review the MCC line-up for common errors and omissions. Click the check mark icon in the tool bar.

CenterONE has found warnings and errors that need attention! Warnings are just reminders for the user to consider, but they do not necessarily mean that the MCC cannot be built as specified.



Items circled below are errors. Processing of the line-up cannot be completed until these items are addressed.

Dealing with Errors and Warnings

Adding Units: DeviceNet Power Supply and Scanner

The first two warnings refer to the DeviceNet power supply and DeviceNet scanner. (You may run final edit again to see these warnings.) DeviceNet requires a separate 24V DC power supply that powers all the communications devices on the network. Not just any 24V DC supply will meet the requirements. For the IntelliCENTER, an 8 A power supply with a very quick ramp-up time (under full load) is required to prevent intermittent communications.

Click the close button on the Final Edit Errors and Warnings message box.

1. To add the power supply, go to the Units window.

2. Click New, then Miscellaneous. Click OK.



3. Scroll down to DNPS—DeviceNet Power Supply and select it.

4. Upon making the above selection, the quantity will appear as “1” and “circuit breaker” will be selected as the disconnect type.

5. Click OK.

A DeviceNet network typically requires a scanner (or a communication bridge) to make the data on the network available to controllers on other networks. A DCS system, for example, would need a means to communicate with this MCC.

For this example, the simplest network interface will be used. A CNDN (ControlNet to DeviceNet) bridge is a device that makes information from the MCC units on DeviceNet available to a ControlNet network. There is no programmable logic processor module. The CNDN receives commands via ControlNet (from a remote PLC or DCS) and passes them through to the DeviceNet network in the MCC.

1. To add a CNDN, go the Units window.



2. Click New, then Miscellaneous and OK.

3. Scroll down to the CNDN option and select ControlNet to DeviceNet Linking Device (CNDN). A circuit breaker type disconnect is suitable, and only one is needed.

4. Upon making the above selection, the quantity will appear as “1” and “circuit breaker” will be selected as the disconnect type.

5. Click OK.

Whenever new units are created, they must be added to the MCC structure.

6. Click on the Layout window. Notice that the two new units are not in the structure, but waiting at the bottom of the page.



7. Click on Utilities and Auto Layout (remember to put the main breaker on the left) to add these two units to the structure. Notice that the two new units have been added, but all the blank doors are gone and there are open spaces. Leave these spaces blank for now.

8. Click OK to close the Automatic Layout window notification.

Fatal Errors

Run Final Edit again, by clicking on the blue check mark icon in the toolbar. The next string of messages are all listed in red, meaning that they are fatal errors that must be corrected before CenterONE can finish the MCC line-up. See illustration at top of next page. All except one of the errors in the fatal error list relate to unassigned node addresses on DeviceNet. The exception is the first error message that indicates at least one feeder circuit breaker unit in the top half of section number 6 must be moved if we are not to overload the vertical power bus in that section.

Remember how you handled that kind of move, earlier in this exercise? Click and hold on the topmost FCB unit in section number 4 and drag that unit to the currently unused location at the top of section number 7. Release and drop the FCB unit there in section 7.



Assigning DeviceNet Node Numbers (Addresses)

1. Go to the Spreadsheet window.

2. In the tool bar next to “Data Displayed,” click the down arrow and choose DEVICENET. The display changes to show each individual unit rather than showing one line for multiple quantities of each unit type. For example, there are now nine lines for 5 HP FVNRs instead of one line with a quantity of eleven.

Manually Assigning Addresses

1. Under the column marked “Node 1,” click on the first white field. If this is the line for the Main Circuit Breaker, nothing will happen. That is because the MCB does not have a DeviceNet device in it.

2. Click on the next line under Node 1. A drop down window will show the list of DeviceNet node addresses. It is possible to manually enter each DeviceNet node number in this manner. This method may be required if the customer wishes to specify each node beforehand. This is particularly useful if the customer is trying to write the DCS program beforehand.



Automatically Assigning Addresses

It is possible to assign addresses (manually) for all nodes on the network. Or, if the customer does not need to specify addresses, CenterONE software has the capability to perform this function automatically.

Click on Utilities in the tool bar and select Auto DeviceNet. Notice that there is now a node number (DeviceNet address) for every unit that has a DeviceNet node.

Click OK on the Automatic Selection of DeviceNet Nodes completed message window.

Final Edit—Take Two

Now it is possible to run the final edit program to check for errors. Note that the check mark icon is “grayed out” or not available in the spreadsheet window. The user must have the Layout window active for this icon to work.

1. Click on the Layout window, then click on the check mark icon in the tool bar to see final edits again. If you get a message that one section contains more than 300A of load in the top (or bottom) of that section, drag and drop one of the feeder breaker units to an open location. Remember, you did that earlier, to manually adjust the layout, but then we did an Auto-Layout again.

2. Click OK to acknowledge Final Edit Completed, No Errors Found. During the final edit, CenterONE will ask to re-add the doors needed to cover the blank spaces in the MCC. Click Yes to this question.

The final edit is successful, so a window appears giving information on the DeviceNet configuration. This DeviceNet network uses the amount of amperes specified above from the 8A power supply. Also shown are the total cumulative DeviceNet drop cable length and trunk cable length in Network Number 1 as it is configured. Your cable lengths may be slightly different, if your layout is slightly different.

3. Click Close to remove this window.



The MCC configuration is complete. At this point, your workup should be saved again.

Documentation Report Generator

A wide array of documentation for your MCC workup is available using the built-in Report Generator.

1. At the top Menu line click on Reports, and then click on Report Generator. If you see a Final Edit advisory screen, click OK on it. You should then see this Report Generator dialog.

NOTE: On the right side in the Report Generator dialog, you should see a listing for an Output Folder with the same name as you called your MCC workup in the initial CenterONE Setups. If you wish, you can modify this Output Folder name. Your Report Generator outputs will be saved into that folder and it will be located atMy Documents\CenterONE\Reports.



2. Click on Select All. De-select the Refresh from Server choice, located to the right of Wiring Diagrams. Your Report Generator dialog should then look like this.

NOTE: Because the lab computers are not connected to the Internet, the Wiring Diagram retrieval (Refresh from Server) will not be able to be done in the lab. If you are doing this CenterONE software tutorial at a computer where you do have an active Internet connection, you may choose to have Refresh from Server remain selected. How your outputs differ will be described below.

3. Click OK at the upper right of the Report Generator dialog.

NOTE: It is possible that a previous user created an Output Folder with the same name as yours and that it has some of their reports in it. If you see an advisory message that there are existing reports in the specified folder, Click Yes, to overwrite them with your reports. Because this is only a tutorial, there will be no reason to save those old report outputs.

You should then see your selected reports being generated, on the screen. This may take a few moments. When that is finished, you should see an advisory message that all selected reports and files have been generated.

4. Click Yes, to go to your Reports folder. There you should see listed several Word documents and some other file type outputs. To get an idea for how these relate to your workup, double click on the document named 002_MCC_Overview.doc. This should open that document in Word for Windows. Notice that this document, which might be considered an important part of a Request for Quote for this MCC, lists the exact parameters you specified for NEMA enclosure type and available fault current (in paragraph 1.0 – General)…the section depth in paragraph 2.0, your incoming line unit type in paragraph 3.0, etc.



Available Reports

Feel free to explore some of the other documents on your own, or see the descriptions and examples that follow. Note: All these Report Generator documents were placed in a folder at My Documents\CenterONE\Reports\Cooling System MCC.

• 002_MCC_Overview.doc – an ‘RFQ’ document, which the user can modify if desired, in Microsoft Word.

• 003_MCC_Summary.doc – a section count and description, unit count, delivery program summary document.



• 004_MCC_Details.doc – a list of the major structure and bus options in the MCC.

• 005_Structure_Details.doc – a more detailed list of structure and bus options and sizes.

• 006_Unit_List.doc – a unit count and basic unit description document.

• 007_Unit_Description.doc – a detailed unit description list, including what options are configured in, where located in the line-up, etc.

• 008 – This is a missing category, unless you have an active Internet connection and requested Wiring Diagram retrieval from our File Server, above. Then, the wiring diagrams specifically for each unit which has been configured by you or another user at least once in the past, will be retrieved as AutoCAD® drawings (*.dwg) from Rockwell Automation’s secure server on the Internet, and a copy of each will be stored in this Reports folder. For example, here is a part of the wiring diagram for the (4) 40 HP starter units you configured earlier in this exercise.



For any units that are new to our system (due to their having a unique combination of options, not previously configured, for example) but which can be configured in the CenterONE application software, a request for the wiring diagrams will prompt our file server to pass that request back into the Rockwell Automation system. There, the needed wiring diagram(s) will be created and sent out to our secure public server for your retrieval. However, please be prepared to wait about 24 hours in those instances, before you will be able to retrieve those newly-made diagrams.

It is not necessary to have a full working installation of AutoCAD just to view or print these *.dwg files. An AutoCAD viewer called Volo View Express® is available for download at no charge, from the Autodesk web site. Go to http://www.autodesk.com/siteselect.htm and select Products and Solutions, to find Volo View Express available for download.

• 009_OneLine.SCR – Do not try to open this output directly. This is a script file created by the CenterONE Report Generator, for use in creating the One-Line specific to the MCC you have configured. However, you must use fully functional AutoCAD or AutoCAD LT to run that script and to get the one-line output. Instructions on how to set up your AutoCAD to do this are included in CenterONE software Help, and also at our CenterONE software web site, at http://www.ab.com/software/pcp/

• 010_Form385.SCR – Just as for 009_OneLine.SCR above, this is a script that must be run in AutoCAD. The final output would include the Details for this MCC workup, including the front elevation, conduit entry and splicing details, etc., all in AutoCAD drawing (*.dwg) format.

• 011_Front_Elevation.BMP – This is a ‘picture’ replica of the CenterONE Layout view of your MCC workup.

• 011_Front_Elevation.doc – This is a rendition of the CenterONE



Layout view of your MCC workup, in Word .doc form.

• 012_Unit_Spreadsheet.CSV – Output from the CenterONE Spreadsheet view of your MCC workup, this is a comma-separated-variable spreadsheet with the units data from this MCC. It would, of course, need to be opened in a spreadsheet application software, like Microsoft Excel, for example.

• 013_General_Documentation.doc – Initially, only one document populates this category. The longer term goal is to expand that General Documentation population with a wide range of documents available, to be produced if pertinent to the MCC being reported on.

• 014_General_Clarifications_and_Comments.doc – The intent of this document is, as the implies, to clarify MCC issues that may not get pointed out or discussed in the MCC workup itself or in the other reports.



NOTE: The nine Report Generator documents that are produced in Word .doc form can be created in a consolidated, single document if that is your preference. The way to do this is illustrated in the following Report Generator dialog screen.

To generate a consolidated report, you need to include one or more of the Microsoft Word-style reports. In this example, we selected five of those reports.

Next, Check the Consolidate box on the right side. Click OK, and the selected reports will be created and saved as a single document, and those reports will be in the order that they are listed in the Report Generator dialog.
