Hi Everyone,
I'm new to Control Expert but currently I'm working with a project in which I have a Slave M580 PLC that is using a NOM0200 module to communicate in Modbus RTU with a Master Display.
After setting up the Channel 1 as a Slave (Address 15) I managed to connect the PLC to the Display and remove the communication error on his screen. Also, using Read_Var i read some datas, which means I was able to set up some sort of communication between the 2 devices.
Do i need also to define a memory area for the data exchange with the display?
In my specifications i need to set up some PDU (Ex: PDU2000, PDU3000, PDU4000,...) read by the Master.
What is the address of the memory area for a certain PDU? Do i need to configure something?
Thanks everyone for your help.
