PM865 to PM867

Hi,

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,

Hrvoje

PM867 controller supports 800xA 6.0 onwards only. It cannot be used on 800xA 5.1 XX system. This controller works only with SM812 module and can support both SIL and NON SIL applications.
