We utilize the Pyramid Integrator PLC 5/250 as a gateway and memory concentrator between our MMI's (WonderWare), Level 2(Process Control system) and a DH+ network with PLC5's and a couple of SLC's.
There is no logic processor in the PI just the Resource Manager, a KA card and an EI card. We currently use a ControlLogix Gateway (no processor) as a second gateway.
~80% of the Wonderware I/O is to and from the memory in the PI. The rest is via one of the gateways (PI or CLX) to the PLC-5's.
100% of the I/O for the Level 2 system (Dec Alpha using Interchange) is to and from the PI.
Does anyone have experience in a migration from a PI to CLX? What are the problems, workarounds that came up? Should we try to emulate our current system using a CLX processor or completly resturcture the communications?
Replies via this list or e-mail appreciated.
