Step 4.2. Configure Modbus TCP/IP Devices

When you create a new device for Modbus TCP/IP communications, enter the following information in the New Device dialog box:

  1. In the Device field, enter the name of the device you are configuring.

NOTE: The following special characters cannot be used for a Modbus RTU device name: \, /, :, *, ?, ", <. >, |, [, ]. If the device name contains any of these characters, the device settings will not be preserved and saved startup will not be possible.

  1. In the Port field, select the Modbus TCP/IP port to be used by the device.

When you click OK to create the device, the Device Properties dialog box opens.

Step 4.2.1

Set general device properties.

Step 4.2.2

Set Modbus TCP/IP properties.

Important: Only one CIMPLICITY device can be configured per physical Modicon programmable controller. Modbus TCP/IP communications will not run with multiple CIMPLICITY devices configured for the same programmable controller.
