We have a customer with a single S1 in a panel running a strategy to communicate with three additional panels each with up to four EB2 racks (11 racks total).
Each panel has it’s own HMI (Windows 7 Panel PC running PAC Display) and does a completely different thing than the other panels. To relieve some of the resource stress on the S1, I suggested they put controllers in each cabinet. (Looking at PAC Terminal, the S1 has at least 16 charts running and a Loop Time of 250 ms, sometimes as high as 500 ms that I’ve seen, which seems excessive).
I guess my question is, should I suggest using an S or R controller or a SoftPAC controller on each HMI PC? I’ve never used the SoftPAC so I don’t know how it compares with a hardware controller.
Any assistance would be appreciated. Thanks.
