I have a SLC 500 1747-L532C/D 5/03 CPU 16k mem OS302
with a panelview hooked to the 485 port.
It also has a 232 port.
I have never been able to communicate with this or similar SLC's using the 232 port, but always have to use that goofy PIC thing that goes from 232 on computer to 485 on PLC with the ribbon cable, the box and the RJ 45 plug.
why is that?
what do I need to do, and what driver do I need to use to communicate using 232 serial ports so I can leave Panelview hooked up and leave the PIC thing in the desk?
It seems like something from the 70's.
