MODBUS Interface to ABB AC 870P


Thread Starter

I will appreciate if somebody answers the following questions related to AC 870 P Controllers of ABB 800xA:

1. How many MODBUS RTU connections possible from CCF 10-P modules?

2. Does CCF 10-P support MODBUS TCP/IP? If not, is separate module available for MODBUS TCP/IP interface to AC 870P?

3. I understand for Profibus DP interface is possible through 9-pin socket at the the front panel of PM 875. No separate module needed. Is that correct?

Many thanks,
