PM865 to PM867
I have a question regarding the new PM867 processor module (for use in 800xA v5.1 system).
Existing PM865 processor with SM811, CI867 module and safety/non-safety IO modules, and SIL/non-SIL applications installed on site became overloaded. So we are trying to find a solution to decrease its load. We don't have a possibility to optimize the programming code, so we have to buy a new processor module. Regarding that, we have two options as I see it:
1. Buy and add new PM864 processor, and transfer CI867 module with modbus TCP/IP application from the existing PM865 module.
2. Buy new PM867 and SM812, and completely replace PM865 (SM811) with PM867(SM812). The questions regarding that are:
- could PM867 work with SM811 (Control Builder safe gives me permission to add SM811 to PM867)
- is PM867 inteded to work only with SIL applications, or can it work also with non-SIL applications and non-safety IO modules?
So in the first option I would have two controllers in control cabinet (PM865 and PM864), and in the second option I would have only one controller (PM867 that replaced PM865). If it's possible, I would prefer the second option.
Thanks in advance,
