Brian, If the two CP's can communicate (on same LAN) the easiest solution would be to trigger the reset from one source. Have logic in, say, a LOGIC/CALC/CALCA block running in one CP and reset both ACCUM blocks. But I sense that this is not doable, otherwise you'd have done it already, no?

Accum1 runs in CP1, node1 Accum2 runs in CP2, node2 I need to reset both accum blocks at the same time. Right now they are close but not close enough which is surprising since both CP's are lightly loaded. I wanting to generate the reset in the CP not in CRON if possilbe. I'm using the CPx_STA:STATION.HOUR parameter currently to do the reset (clear).
