I have read in this forum that the rung comments and descriptions are stored in the .rss file and not on the plc, and I get that. I have also read a non-descript statment that it is possible to get the rung comments to show on the plc save copy of the program. I would like to know how to do that if you guys could be so kind as to let me know how. I have an AB SLC 5/04, and I am able to connect to the plc through RSLogix500 via RSLinx and the appropriate cables. Also, I have a copy of the program saved on my PC with the Rung comments and descriptions. I have tried opening the connection to the plc through RSLinx, then opened the program with the comments. I tried downloading from that point, but I just get a node error. If I open the plc program, (go online) i do not get an error, but cannot seem to figure out how to change from one program to another. Any help would be much appreciated.
