IA OPC 5.1 Causing a backplane comm error w/ GE PLC 90-30 374+ CPU

[JasonPKelly]

Hello,

So here is what's going on. I have a Series 90-30 Setup W/ a high capacity p/s and a 374+ CPU. I am trying to find the correct configuration of communication to replace the 364 CPU which is now obsolete. I read the notice thoroughly and to my understanding the 374+ with a rev of at least K (or something like that) and a high capacity p/s should be the direct replacement. Now I can connect via serial no problem. But when trying to connect via ethernet for Industrial Automation OPC 5.1 I receive a configure connection error as well as a system fault on the plc "backplane communications with PLC fault:lost request"

any ideas?

It cannot work with 374 via Ethernet...

if you need to comunicate With 374 or 372 cpu with lookout driver if possible by GE versamax ethernet driver

the problem is the limit of register to %r02048

The protocol for ic200cpuE05 is like the 37x 90.30 cpu
