SLC Instructions number of clock cycles

[mordred]

I've been looking for a listing of clock cycles each instruction uses for the SLC and micrologix instruction set. The purpose of this is to develop some rules streamline a program into using the minumum number of clock cycles needed for cycle timing. There is no project at the moment that I need this for after all most applications have plenty of time before cycle times becomes an issue however I would like some reference or listing that I can refer to in case one crops up. I couldn't locate this information in the SLC instruction set

the new books don't have - but the old ones did ...

take a look at the snapshot of a chart attached below ... would this help? ... it's in microseconds - not clock cycles - and it's not included in the new versions of the instruction set manual ... if this is what you're looking for, maybe we can come up with a copy for your files ...

That will work Been looking all over for such a listing perhaps if I search under execution times I may get better results

found it once I realized they referred it as execution times I've got a decent listing

the list is more complete in this as opposed to the individual instruction sets of micro and SLC 500 this one lists per both. Includsing the rung execution of nested vs extended rungs which was some information I was having trouble finding
