Replace PM866 to PM891
Hi to All,
I have to replace PM866 controller to PM891 controller.I have todo this in a plant during shutdown.What are the things I have to keep in mind while replacing.
Is their any manual which shows this process or steps which I have to follow.
1. Is PM866 has direct connected I/Os?? -- PM891 Wont Support
2. Existing configuration is redundant configuration?? -- Cables and other stuff will differ
3. Is PM 866 is having serial communication from Com3 port ?? no com3 port in PM891
4. Is yout Xa version supports PM891 Frimware,
5. Have you check from Contol builder M, in replace unit senction PM891 is available??
