I tried with 1747-UIC,( in device manager showing USB to serial)using laptop.
Danial
Then I tried with desktop having RS232 port and connected using the cable, not succeeds,
What communication setting i have to do on the proficy machine edition?
your GE supplier should know, it's about $150..
Do not use this... to many variables and you should try to eliminate them.
I would think that you need com 1, do you have another PLC to test communication? is your pinout the same as the diagram that I sent you?
Regarding com1, I have com 2 and com 3 serial port, I dont't have com1 port, how can i modify my com2 as com1 .
