Allen Bradley PLC-5 1785-ENET IGS and MSG

[shanefaulkner]

We have many sites with PLC-5s and 1785-ENET sidecars that are being pounded pretty hard by the GE IGS driver (Kepware) and iFIX/Historian software, but they seem up to this task.

Would it be a bad idea to also hit these sidecars/PLC5s with MSG reads/writes from a new separate 1756-L73 ControlLogix processor? I am concerned about overloading this old beast and losing HMI/historical/MSG info.

I used to hit these things pretty hard with Wonderware for 12 HMI screens and just data recording, and msg blocks to 7 other PLC's. think there is a way to check the overhead on the plc.
