Folks,

I've been working on a 0-TB with a PMC-L and I'm trying to understand some of the differences in the older ladder representation as compared to newer PMCs. For example, a SUB24(TMRB) is a fixed timer, but the ladder for the OT-B shows one instance represented as shown in the attached screenshot. This would be a count up timer 11, fixed at 500ms, but what is the timer doing with diagnostic address D400? If anyone knows where a programming manual for the PMC-L or FLADDER might be hiding or at least something that explains the older format of the SUB functions, it would be a huge help.

Thanks,

Dave
