Hi everybody
I am using CpP1E plc Wich as you know, has rs232, rs485 and peripheral ports.
Actually I use the RS485 port for a HMI network.
Also, I need to make another modbus network to transfer some binary signals (a fault module) to the plc.
So, can I use the RS232 port of the plc at the same time as the master device?
Thank you in advance
