RS Logix 500 Program wont run in Emulate

[Fircombehall 0]

Hi,

I'm trying to run a program in rs logix emulate 500 and it is going into fault with the fault description being "internal file error". It then proceeds to say file 103, rung 0, instruction 2 is where it seems to be stuck. I know the program is good because it is currently running live on a site with no issues. I read it may be that the rslogix emulate that i am using may be too old for the program it's trying to emulate.

Has anyone come up with an issue like this before? I have screenshots but it says i can only upload a few mb of data so can't attach them to this topic.

Any help greatly appreciated.

Emulate does have limitations. See pdf

Thanks for your reply Mickey. It looks like it may be an MSG instruction causing the error. I’ll remove it from the program and try it again.
