Answer question

CHANGING PM864 TO PM866

HI,

This is my new project using ABB DCS/PLC and in this project i need to change a PM864 CPU to PM866 redundant. This PM864 has 10 S800 remote I/O via CI840 Profibus and each S800 has 7 I/O slots (2 DI814, 2 DO820, 2 DO821 and 1 AI810). We need to add 2 S800 remote I/O:

First one needs 1 AI810, 4 DI814 and 10 DO810

Second one needs 6 AI810, 9 DI814 and 3 DO810.

My questions are:

1-Will my new PM866 able to control all this remotes? What about firmware and software compatibility to program this new CPU?

2-Will these remotes work with this quantity of slots? How many slots can we insert in one S800 remote?

3-Has anyone ABB ordering code for each hardware described above (PM866, CI840, DI, DO, AI slots)? If someone knows these codes, please send me.

4-Could anyone send me hardware catalog of each hardware described above?

Thanks in advance.

Gabriel.
