I have an AB micrologix 1400B that is talking to a Survalent SCADA system on DNP3 (serial not enet). I can send and receive 16 bit analogs as well as send a binary input to the SCADA system.
The problem is I cannot receive a control (binary output) from the SCADA system. I have the BO file set up with the config file on the PLC. I tried changing the config file to all 1's and 0's neither works. The SCADA rep tried sending every type of binary output nothing works.
DNP seems to be quite complicated and I have very little experience with it, mostly used in power generation, transmission and distribution.
I checked the archives and the web there is very little info on AB PLCs with DNP.
I didn't have much trouble with the analogs or BIs, getting very frustrated. Unfortunately the SCADA rep doesn't know any thing about AB PLC's nor does he know anyone who does.
Any help would be greatly appreciated.
