5.4.7.3 Modbus TCP
This page allows you enable or disable the Modbus TCP connections, configure transfer table
of Modbus communication, as well as check the connection status.
CIM support maximum four Modbus TCP connections simultaneously at most. CIM will share
the connections if it acts as a Modbus TCP server, Modbus TCP client at the same time.
When you set up Modbus TCP communication between two CIM, do enable S7 connection
first.
When you set up Modbus TCP communication between a remote device to CIM, make sure
Modbus TCP communication is enabled in the connected remote device.
