Assistance Required for Ladder Logic Implementation in EcoStruxure Machine Expert Basic with ATV12 and TM200C16R

[Adarsh_1]

I am currently working on setting up ladder logic in EcoStruxure Machine Expert Basic. I have connected an ATV12 Variable Frequency Drive (VFD) to a Schneider PLC TM200C16R via Modbus RS485 communication.

I require assistance with the following:

• Setting up Modbus communication between the PLC and the VFD in the software.
• Developing ladder logic to control the VFD (e.g., start/stop, speed control).
• Configuring both the ATV12 and TM200C16R with the correct parameters in EcoStruxure Machine Expert Basic.

I have already created a ladder logic program, which I am attaching here. Could you please review it and provide guidance on any necessary improvements or corrections?

Hi, in Machine Expert Basic is a sample Project (called TVDA) integrated which shows you to integrate a ATV12 ond TM2xx. The project is for TM221 but the way on TM200 should be identical.

You need to configure in the ATV12 that the command and the speed are set via modbus RTU and not via terminal.
