1 Introduction

1.1 Overview

The Limitorque Master Station II is a revolutionary step forward in control technology. The device iscapable of controlling up to 250 actuators, offers full redundancy, provides easy-to-use HMI interfaces,and allows for high-speed data-transfer via a Modbus DCS port or Modbus Ethernet port. In addition, abuilt-in web server can be used for monitoring network status from any remote station using TCP/IP. Webserver operation is covered in Section 18.

1.2 User Rights Overview

The Master Station requires users to login. Three user role levels are provided: View, Control, Configure.Each role includes the rights of the lesser roles, i.e. Control includes View’s rights, and Configure includesControl’s rights and View’s rights.

View: the user can view the network status and the activity log. No control or configuration functionalityis available.

Control: in addition to View’s rights, the user has the ability to control MOVs.Configure: in addition to Control’s rights, the user has the ability to configure the Master Station and

the Network.

The default passwords for each role are:

View: 100Control: 200Configure: 300

These passwords can be changed by the Configure user. Changing passwords is discussed in Section 9.




1.3 Login

When the Master Station starts, it loads the default startup screen (Figure 1-1).

Figure 1-1: The Introduction screen

Touching any part of the screen will load the login screen (Figure 1-2).

Note: If the screen is blank and the green LED is illuminated, touch the display to exit the screensaver mode.

Figure 1-2: The Login screen

Note: Each user level must be a unique password.

Passwords can be four digit numbers. The correct password for View, Control, or Configure will take theuser to the Main Menu (Figure 1-4).

If “Help” is pressed on the password screen, the user is given the opportunity to reset all passwords tothe defaults (Figure 1-3). Please contact Limitorque to obtain the reset password.

4.2 Master Station Wiring Requirements

The network cable connects the field units to the host controller or Master Station. Belden 3074F, 3105A,or 9841 shielded, twisted-pair cable should be used. The use of other cables may result in a reduction ofinternodal distances or increased error rate, and is the user’s responsibility.

Belden 3074F Specifications

• Total cable length between repeaters or nodes with repeaters: up to 19.2 kbps: 5000' (1.52 km)

For loop mode, this is the total length between operating field units. If a field unit loses power, the relaysinternal to the field unit connect the A1 Channel to the A2 Channel, which effectively doubles the length ofthe cable (assuming a single field unit fails). To ensure operation within specifications in the event ofpower failure to field units, this consideration must be added. Example: To ensure operation withinspecification when any two consecutive field units lose power, the maximum length of cable up to 19.2bkps should not exceed 5000' (1.52 km) per every four field units. See Section 3.1.2.3, Network CableConnection to Host Controller or Master Station.

Key Specifications

• Resistance/1000 ft = 18 AWG (7 x 26) 6.92 ohms each conductor (13.84 ohms for the pair)• Capacitance/ft = 14 pF (conductor-to-conductor)• Capacitance/ft = 14 pF (conductor-to-shield)




Belden 3105A Specifications

• Total cable length between repeaters or nodes with repeaters: up to 19.2 kbps: 4500' (1.37 km)

For loop mode, this is the total length between operating field units. If a field unit loses power, the relaysinternal to the field unit connect the A1 Channel to the A2 Channel, which effectively doubles the length ofthe cable (assuming a single field unit fails). To ensure operation within specifications in the event ofpower failure to field units, this consideration must be added. Example: To ensure operation withinspecification when any two consecutive field units lose power, the maximum length of cable up to 19.2bkps should not exceed 4500' (1.37 km) per every four field units. See Section 3.1.2.3, Network CableConnection to Host Controller or Master Station.

Key Specifications

• Resistance/1000 ft = 22 AWG (7 x 30) 14.7 ohms each conductor (29.4 ohms for the pair)• Capacitance/ft = 11.0 pF (conductor-to-conductor)• Capacitance/ft = 20.0 pF (conductor-to-shield)

Belden 9841 Specifications

• Total cable length between repeaters or nodes with repeaters: up to 19.2 kbps: 3500' (1 km)

For loop mode, this is the total length between operating field units. If a field unit loses power, the relaysinternal to the field unit connect the A1 Channel to the A2 Channel, which effectively doubles the length ofthe cable (assuming a single field unit fails). To ensure operation within specifications in the event ofpower failure to field units, this consideration must be added. Example: To ensure operation withinspecification when any two consecutive field units lose power, the maximum length of cable up to 19.2bkps should not exceed 3500' (1 km) per every four field units.

10 Hot Standby Configuration

10.1 Overview

The Master Station is capable of Hot Standby Operation. Two identical processing units communicate witheach other via an Ethernet 10-BaseT connection. One processing unit is configured to be “Hot” while theother unit is configured to be “Standby.”

10.2 Configuration

Each unit must be configured for TCP/IP communication. This is accomplished via the HMI interface onthe “Configure Ethernet Port” screen (Figure 10-1).

Figure 10-1: The Configure Ethernet Port screen

In addition, the “Hot Standby IP Address” must be configured with the other processing unit’s IP address.For example, the Hot processing unit must have the Standby processing unit’s IP address in the “HotStandby IP Address” section, and the Standby processing unit must have the Hot processing unit’s IPaddress in the “Hot Standby IP Address” section.

IP addresses are configured by touching the “Edit” button on the row of the address to be configured.This will allow the user to set the octets of the IP address from the left to the right, one octet at a time.Use the “Next” and “Back” buttons on each editing screen to navigate between screens.

Following the successful configuration of the IP address information for each unit, further configuration isnecessary.

The “Configure Hot Standby” screen of the HMI (Figure 10-2) allows the user to configure the startupmode of each processing unit, displays the current state of each processing unit (i.e. Idle, Standby, or

Hot) and allows the user to force the units to switch roles such that the Hot unit becomes the Standbyunit and the Standby unit becomes the Hot unit (Figure 10-3).

Figure 10-2: Configure Hot Standby screen

When configuration changes are saved in the Hot processing unit, these changes are transfered to theStandby processing unit. Therefore, the network configuration, DCS configuration, and otherconfigurations only need to be performed once. The configuration for the Hot Standby Parameters areunique for each processing unit, however, and as such must be completed independently for eachprocessing unit. The Hot Standby configuration is not transferred from the Hot unit to the Standby unitwhen the configuration is saved.

10.3 Operation

Under normal operating conditions, the Hot processing unit will transmit incremental data updates to theStandby processing unit via the Ethernet connection.

The Standby unit will also monitor the communication on the network to ensure that the Hot processingunit is viable.

In the event of a Hot unit failure, the Standby unit will smoothly transition into the Hot role. In addition, aforced switch may be imposed. The transition period from Hot to Standby and Standby to Hot takes under20 milliseconds to complete.

Each processing unit is capable of three states: Idle, Standby, and Hot.

Idle state: the processing unit is active, will accept incremental updates from a Hot unit, but will not performthe Hot unit’s duties nor will the processing unit switch to Hot state should a Hot failure be detected.

Standby state: the processing unit is active, will accept incremental updates from a Hot unit, and willswitch to Hot state should a Hot failure be detected.

Hot state: the processing unit is the Hot unit and will perform the Hot duties of Network polling andincremental updating of the Standby processing unit.

A state change can occur in any of the following conditions:

Hot Unit Failure: the Hot unit fails to send incremental updates to the Standby unit and there is nonetwork traffic.

Hot-Standby communication failure: the Standby unit is not receiving incremental update informationfrom the Hot unit but detects Network traffic. The Standby unit will zero its database and set an alert error.The HMI will detect this state and will display “Idle” instead of “Standby”.




11 Network Status

The Network Status screens (Figure 11-1) present an overview of the entire network, 25 MOVs per page. There are tenpages total. Use the “<< Back” and “Next >>” buttons to navigate between the screens.

Figure 11-1: Network Status Page 1 screen

There are two levels of information presented on this screen.

The first colored bar (left) indicates communication status. Green is good communication on both channels A and B.Yellow indicates Channel A communication failure. Blue indicates Channel B communication failure. Red indicates failureon both channels.

The second colored bar indicates MOV Fault status. A green bar indicates no fault, while a red flashing bar indicates MOV fault.

Touching a MOV will take the user to the View MOV Status screen. The View MOV Status screens are discussed inChapter 13.

18 Touch Panel Backlight

When the touch panel backlight burns out, the panel’s status LED will turn orange. The HMI is programmed for touchoperation to be disabled when the backlight burns out, which prevents the panel from sending commands to the PLC.

The touch panel unit uses a CCFL, long-life type backlight. The actual life of the backlight however, will vary depending onthe operating conditions, and replacement may be required. The backlight has a life of 30,000 hours (approximately 3.4years), when the backlight is lit continuously (time required for brightness to fall to half its normal level).

Note: The touch panel screen saver feature is enabled to prevent continuous backlight operation for a longerbacklight life expectancy.

Pro-face part number: GP377L/S-BL00-MS

Warning• To prevent an electric shock, be sure the touch panel’s power is disconnected from the power supply prior to

changing the backlight.

• When the power has just been turned OFF, the unit and backlight are still very hot. Be sure to use gloves to preventburns.

• The backlight is very fragile. Do not touch the glass tube directly or try to remove its power cord. If the glass tubebreaks, you may be injured.

Use the following steps to change the backlight. Be sure to use gloves.

1. Turn OFF power to the Master Station. Disconnect power.2. Remove the power and serial cables from the touch panel and remove from the Master Station.

3. Unscrew the panel’s two (2) top face attachment screws.4. Push down on the lock clip and open the panel’s rear cover.5. Disconnect the backlight's power connector from the inverter board. Do not try to pull the cord out of the backlight.6. Push the backlight's lock tab to the right to free the backlight, then pull it upwards and out of the unit.





7. Insert the new backlight and slide it into its slot until the lock tab can be clicked into place.8. Attach the new backlight's power connector to the inverter board.9. To replace the panel's rear cover, insert the cover’s guide tabs into the case's guide slots and close the cover. Be

sure that the rear cover connector and the front unit connector are correctly aligned10. Install the panel's two (2) top face attachment screws.

11. Insert the touch panel into the Master Station by first attaching the power cables and serial cable, then install thetouch panel retaining clips.

12. Attach power to the Master Station and Turn ON the Master Station.
