I had a problem with SLC500 - the processor is SLC5/03 and I am using RS232 interface cable.
I configured the RS Linx as DH485 UIC devices driver and every thing was OK, than I made a trial program and downloaded it to the PLC, it was downloaded good and it is working but I lost the communication with the PLC after this, I made every thing again but I am facing a problem that the RS Logix is not connected to the processor.
I saw some one asking about this problem on one forum and this is was a note from one reply:
"When you download a program to an SLC family controller, the last thing the RSLogix 500 software does is check the Communications channel configurations and compare them to the current settings in RSLinx. If these are different, the software presents a warning letting you know you *may* lose communications on the current or the other channel of the controller.
It is absolutely vital that you pay attention to those messages when they appear."
I belief that this what happened to me while downloading the program and I clicked yes.
So what would be the solution for such problem now to retrieve communication with the PLC?????????
