RS Logix 500 issues

hodgie_2k · Jun 23, 2010

i am having some issues. I have created a program in RSLogix 500 and uploaded it to a MicroLogix 1000. The program is running properly but it is not pulling in the outputs in the program even though it is getting the inputs. I can force the outputs on and they work.

Does anyone have any ideas what the problem could be?

Cheers

Processor in Run mode and not in Test mode? Not sure if 1100 has a test mode. Used a JSR to jump to ladder file where the code is, if the code isn't in LAD 2?

If you can, post your .RSS file and someone can help you look. ( zip it first then post it)

The MicroLogix 1000 (1761-xxxx) must be placed into RUN mode with RSLogix 5000 software; it doesn't have a keyswitch.

The MicroLogix 1100 (1763-xxxx) uses the LCD and keys to set itself into RUun, Remote, or Program modes, or you can use RSLogix 500 to set the controller into Remote Run or Remote Program modes.

In either case it's most likely that the subroutine containing the output logic is not being executed by a JSR instruction.

I agree that posting the *.RSS file is the fastest way to have it reviewed !

RSLogix issues

I am working on uploading the program

I can fire the outputs if I put a force on but they won’t fire when the program is running. I am getting the input in the rung on the program but it’s not energizing the output in the program.

I’m not sure weather it is a setting in RSLogix that I haven’t got set-up right. I’ve never come across the problem before.

As Ken has already mentioned, either the plc isn't in Run mode or you are not calling the subroutine.

As the rest mentioned, just to make it more clear
