1-4 Cable Diagram

Omron HostLink PLC can transmit the data through RS 232 or RS422 serial communication. It is suitable for the small amount data transmission. If some devices need high transmission speed and the bulk data transmission, users can use Ethernet for data transmission. To connect OPC Server to Omron C Series PLC, CJ1M-SCU41/ CJ1M-SCU21 (RS232/RS422 serial module) communication module should be installed. The cable diagram is shown as below. Please refer to the Appendix A.

Usually, RS232 serial port is used for short distance communication; on the contrary, RS422 or modem is the better choice for the long distance communication.

RS 485 is only used for the communication between PLCs.

2-1 Communication Setting of Omron PLC

Sample PLC Type Omron CQM1H-cpu21 Communication Module The Port2 of Omron CQM1H cpu

The Address Space tree control in the Configurator, shown in the figure below, sets the properties and connection parameters for the following items: • Ports • Devices • Folders • Data Items

Data items can be organized hierarchically. It is similar to organizing directories and files on your computer's hard disk. The OPC Server offers several levels of hierarchy. The Configurator module uses the terms “Folder” and “Data Item”. A folder can contain additional folders and also data items. The data items are always the branches in the tree control hierarchy.

The hierarchical structure of the folders and data items helps to organize the devices and tags, as shown below.

17

2-1-1 Port Define

A port is equivalent to a physical serial port in the computer. To correctly configure a port means to set up a serial port as a File name (COM 1, COM2), communication speed (Baud rate), and protocol characteristics: RTS flow control, Stop bits and Parity scheme. When the Parity checking enabled check box is not checked, it will force the server to ignore the parity bits in the message. 1 Select Address Space Edit New Port

You can also use [Ctrl+T] as the shortcut to create a Port.

18

Port Define Operation platform

Item Description

Specify a name of the new device. The special symbols such as ｀+＇、/、*、- are not allowed.

Define the Port number.

The value must match the Baud rate value of Omron PLC.

The value must match the Data length value of Omron PLC.

The value must match the Stop bit value of Omron PLC.

The value must match the Parity scheme value of Omron PLC.

Also, check ”Parity checking enabled”

19

Particular setting will be required if the device works under RTS flow control. If not, please choose” Disable”

Select this item if the device works under CTS for output flow control. If not, just skip this item.

All of the devices under this port will in the simulation mode. Simulation function will simulate the real communication situation between devices and OPC Server.

Apply: Saves all changes specified in the properties dialog box.

Reset: Undo the setting configuration Add New: Add the new Port

20

2-1-2 Device Define

Every device is connected to particular port, so it logically creates the second level in the Address Space tree. Each device is represented by its symbolic name, and is uniquely identified by the Address value. It is impossible to have two devices with the same address connected to one port. Setting up a device requires configuration of its unique address, type, timeouts and optimization parameters, as shown in the figure below. 1. Select Port Edit New Device 2. You can also press [Ctrl+D] as the shortcut to create a Device.

21

Device define Operation Platform

Item Description

Specify a name of the new device. The special symbols such as ｀+＇、/、*、- are not allowed.

The value must match the Host Link unit number.

Device Type: “Host Link”

Timeout parameters (separately for reading and writing data) specify the period of time (in milliseconds) the server will wait for a response from the device:

Read/Write: Amount of time (in milliseconds) the OPC server will wait for a response (read/write) from the device.

22

Timeouts to Suspend: The number of consecutive read/write attempts that timeout before the OPC server will suspend communication with the device.

Suspend Period: Amount of time the OPC server will wait before attempting to reconnect to the device. Note: The Suspend Period setting can be decreased to reconnect faster with a device that has been restarted, but this will cause the OPC server to generate more network traffic while a device is down.

The server tries to optimize the communication with the devices by requesting as much data as possible in one message. Consecutive registers are merged together into one request for efficiency.

Define the Parameters. You could do it in detail in the [ Device Parameters ] on the Tree View

All of the groups and data items under this device are in the simulation mode. Simulation function will simulate the real communication situation between devices and OPC Server.

Please see “UMHMIOPCEA.pdf”.


Reset: Undo the setting configuration Add New: Add the new Device

23

2-1-3 Folder Define

Folders can be used to group items logically. You can configure as many folders as required. Each folder can even have subfolders. The OPC Server supports up to three folder levels. The use of folders is not required. If desirable, the configuration could just contain data items without any folders. But most likely this will only be useful if the application does not demand too many persistent tags. Select [Device] or [Folder] on the Tree View. Press the right key of the mouse and select [New] [Fold]

24

Folder define Operation Platform

Item Description

Specify a name of the new folder. The special symbols such as ‘+’、/、*、- are not allowed.

All of the data items under this group are in the simulation mode. Simulation function will simulate the real communication situation between devices and OPC Server.

Please see “UMHMIOPCEA.pdf”.


Reset: Undo the setting configuration Add New: Add the new Folder

25

2-1-4 Data Item Define

A Data Item represents a register in the device or a range of registers. A symbolic name and description is associated with the data item. An OPC client can obtain the data item description. The actual OPC item name (tag) is compounded from the Address Space root, the names of the folder and its subfolders, and the name of the data item. Data items can be located in any folder, even in the root of the address space. The steps to create the data item (tag) are as below. Select [Device] or [Folder], Press the right button of the mouse, it will show you the Popup menu. Then select New Data Item

26

Then define the data Items, the picture is as below：

Item Description

Specify a name of the new data item. The special symbols such as ‘+’、/、*、- are not allowed.

Description of Data Item

Register/ Replay Type: IO Relay, DM Area, Holding Relay, etc

Look for more information in Chapter 1.

Data Type： IO Relay 　 Bool DM Area 　 Int、UINT String 　 When selecting String type, you must specify the data length

From the starting address to access the data by block, not point to point to access the data. It could speed up the communication speed. You do not have to define a lot of items to get the values. Using [Vector] function will let OPC server put the values into the arrays.

This value specifies the data item address (register number) in the device data space.。The gray column shows the decimal value.

27

“Read Only” does not allow you to save new value into OPC Client.

If the data type is UINT, you can choose the number of bits and analyze the value and put into this item. Bit# means the starting Bit No. Count means the constant Bits number.

To get the data value converted according to a prescribed form, choose one of the predefined or user-defined conversions.

Simulation function will simulate the real communication situation between devices and OPC Server. Executing “Monitor View” or press F12 as the shortcut, the “Tag Value” will keep changing for testing the connecting situation.

To test the client functionality, choose a Simulation Signal from the Signal drop-down list and check the Simulate check box. All levels in the Address Space (port, device, folder, data item) support the process of simulation (Simulate check box). The parent list in the tree is superior; it has a higher priority when deciding to simulate the data item or not. In other words, a data item is simulated, if it itself has a simulation selected, or if any of its parents has the Simulate check box checked. (It may be simulated even if its Simulate check box stays unchecked)

If checked, the data item will offer constant parameter value, because Manual setting is of the highest priority. The changes in the configuration take effect only when the server reloads the configuration (on startup).
