Tried it both ways, one calc block resetting both accums in different nodes and identical calc blocks resetting accums in each node. Also, I added the TIM instruction to the calc blocks in each node to see if the clocks are off. They appear to be the same. Period and phase of CP's, calc's and Accum's same.

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).
