Brian, The Master Timekeeper is supposed to keep the internal clocks of all stations (including CP's) within +-1 second, previous to V8. So your two CP's (worst case) could be almost 2 seconds difference. This is the best resolution you should expect to see. If that is acceptable, then you can try the period phase items, below. But remember that you need a 1/2 second or at worst 1 second period. Check to see if you have OM_Scanner overruns on both CP's Terry Doucet, Eng. Objet : Re: [foxboro] Accum Block Reset Maybe check that the phase and period are the same in both CPs. Also try to move the compounds to get them at the begging of the list (compounds and blocks) that way the CP will execute the blocks als most at the same time. I guess that both cps are on the same network and running the same system hour.
