First off I am new to this.
I have (6) radars on different tanks. At the PLC I can connect to any 3 in any configuration I want and get radarmaster program to communicate. If I land any 4th radar I can not communicate with any of the radars. I have tried swapping out any configuration of tanks and its always the same I can get the first 3 but as soon as I go with 4 it won't communicate.
This system has been installed for 4-5 years and I was told it had been working. Few months ago it was found no longer working.
Rosemount has had me track all the shields and isolate them at the PLC but I still have the same issue.
Any Ideas?
Corey.

What NI software/hardware are you using? How are you communicating with the PLCs?
