Is there any one-shot instruction in sysmac studio? I am running a simulator to test the program but I can not work with LD and LDN instructions.

I have been troubleshooting another engineers logic. There is a couple lines that have real world inputs, IE: I00100 and I00101. Each has it own rung, these inputs are POSCON and feed a reset coil each. One line works fine, one does not. I have verify the inputs are transitioning from off to on, but one reset works, and the other does not. The processor is a CPE-100. Is there a problem using real world inputs with the POSCON instruction? The results are very reliable, the same issue happens every cycle, never any variation. I'm just trying to make sense out of it before changing a "standard" logic program, without explanation. I am a hired gun engineer here for a few months. Don't want to make unnecessary waves.

OK so this is driving me nuts, because I had this whole program just about finished and working fine, until I deleted it Now I don't remember how I did it, if could just get past step 2 in the attached "Scope" I'd be fine and could do the rest myself, I'm kindof a beginner to ladder logic and I'm using RSLogix 5000 SCOPE.docx

FC2 Toggle a bit View File This logic demonstrates how to use a condition to toggle a bit. Any bit-level condition may be used such as I, O, M, C, T, DB. Only two rungs of logic are required. Submitter pop29684 Submitted 03/22/16 Category PLC Sample Code
