Writing to M340 PLC over modbus tcp from Geo Scada?

Anonymous user · ‎2021-12-09

Hi, I am really new to Geo Scada.

I have managed to read an analogue and digital address from an M340 plc over modbus tcp using the Modbus-Simple and Modbus-Advanced selection in geo scada and have it displayed in the HMI.

I am now trying to crate a basic push button that writes a bit back to the PLC over modbus tcp.

Can someone provide some guidance as to how to perform a modbus tcp write with Geo scada.

I would really appreciate any guidance.

Update: Got the analogue and digital write working. Still trying to get my head around stuff.

Thanks
Joshua

You could tell us how you got it working Josh 🙂

That way when someone else comes along looking for the same answer, they will see your question and the associated answer.
