Mason and I are out here now doing the leg work to document the current SCADA/PLC network here in the new side of the plant called CP4000.
Our issue is SCADA is extremely slow to get data to/from this new PLC. There is a fiber line coming out here, so pretty sure it's not due to a slow trunk line.
There are about 30 VFDs/Smart Overloads in this MCC, plus three other PLCs that the CP4000 PLC communicates with. All of this is on the same managed switch and the same port on the CompactLogix PLC, along with the connection to SCADA.
We are thinking that by isolating all the IO to one of the two NICs on the PLC, thereby getting it off of the main scada net, that will help. But we are unsure of the exact logistics of such.
I will forward the result of our work here today, and we can discuss further.

Hey Kevin! Yes, I do! I would love the opportunity to show them our IT capabilities as we have been trying to land them as an IT client for a good while.
What can I do to help?

Hey Chad!
Do you have a good background in VLAN implementation? If so we could use your expertise at South County Sanitation.
