Modbus TCP
CM1-T connected to Schneider M241 Series PLC using Modbus TCP
This demonstration and example video shows how to connect a CM1-T Cool Muscle motor to a Schneider PLC using Modbus TCP. The video further demonstrates using the CM1-T library to control and monitor the motor with standard PLCopen (MC) function blocks. The demonstration walks you through the following steps
Starting a Machine Expert project
Adding the CM1-T IEC 61131-3 PLCopen Motion Control library to the Library Repository
Adding the Industrial Ethernet Manager Device which in this instance acts as the Modbus TCP Master
Adding a Generic Modbus TCP Slave to connect to the CM1-T as a Modbus Slave
Creating and setting up the Modbus channels with Read/Write Multiple Registers (Function Code 23)
Mapping the Modbus channel data to the CM1-T variable instance
Calling multiple library functions to run and control the CM1-T through visualizations.
