I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds
I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1).
Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."
If your Control Win is the Modbus "Master" then your configuration should be something like:
Modbus_COM (Serial port)
- Modbus Master (this is the Control Win SoftPLC actively setting up the communication)
- Modbus Slave (this is then your WAGO 750-315)
You need to add channels to the Modbus Slave configuration to inform the master which variables to read/write from the Wago module.
The way you configured it now, the Control Win is also a slave.
PS, don't forget to put the PLC (Control Win) in Run.
