c. Select the devices to remove and push OK. Confirm to remove the selected devices from the
telegram list.
Note: Use the drag and drop function to change the elements on the Telegram list. Push and hold on the element
and move the device or tag to the new position. Make sure to update the PLC configuration accordingly after the
elements are moved.
6.5.4 Configure the Modbus TCP
Use the Modbus TCP/IP to connect the controller to measurement and control systems that use the
TCP/IP protocol for data transmission.
Make sure that all of the necessary electrical connections are complete. Make sure that the Ethernet
port in the controller is configured to Modbus TCP. Refer to LAN connection on page 25.
Note: To upgrade a controller to have Modbus TCP/IP, refer to Enter license key on page 43.
Configure the controller to use the Modbus TCP communication protocol as follows:
1. Push the main menu icon, then select Outputs > Modbus TCP.
2. Set the Modbus TCP button to on.
3. Select an option.
Option Description
Modbus TCP Sets the Modbus TCP to on or off.
IP address Shows the IP address.
TCP Port Shows the TCP Port.
Telegram Manages the Telegram data structure. Select the devices and the device data tags in
the Telegram. Refer to Configure the telegram on page 38.
Modbus address Sets the address (1 to 255) of the Modbus secondary device configured in the
Telegram menu.
Virtual modbus
slave
Adds virtual secondary devices. The virtual secondary devices are copies of devices
configured in the Telegram menu. When set to on, the virtual device is enabled. When
set to off (default), the virtual device is disabled.
Data order Sets the byte sequence for the transmission of floating point values. A floating point
value has 4 bytes. The floating point value is only data of the configured slaves.
• Normal (default)—The pairs are not changed.
• Swapped—Changes the first byte pair with the last byte pair.
Note: An incorrect setting in the Data order menu can cause small changes in the
floating point values (moved in one register).
Simulation Simulates two floating point values and errors (or statuses) to replace an instrument.
The first floating point value goes through a ramp between limits set in the Minimum
and Maximum menus.
• Simulation—Enables or disables the simulation. Options: on or off.
• Period—Sets the time in minutes (0 to 1000) for the first floating point value to go
through the full range between Minimum and Maximum settings.
• Maximum—The upper limit for the first floating point value. Range: 0.0 to 1000.0
• Minimum—The lower limit for the first floating point value. Range: 0.0 to 1000.0
• Error—Sets the value in the first simulated register. Range: 0 to 65535
• Status—Sets the value in the second simulated register, Range: 0 to 65535
• Toggle—Changes the direction of the simulated ramp application.
