Modbus Serial Passthrough

Started by Roze, 21 Feb 2019

Hi,

is it possible to pass a com-port from the computer to a simulated PLC-session in CX-Programmer? I can't get enough budget from my boss to buy a play-PLC for bus-experimenting, but I can buy a RS485 to RS232 adapter.

Since I can't emulate MODBUS messages, I'd like to connect to a physical network during simulation.

Edit:

Also, if anyone would be so kind: Would this be a sane way of implementing serial communication?

//Kind regards.
