Secondary Connection to Controller Lost Error keep coming
We are facing an issue with our PM891 redundant controller. Controller was running without any issue for the past 6 months, suddenly we are finding an System Alarm "Secondary connection to PMS lost". PMS is my controller name. when we checked the Ethernet port configuration, we found error 16#50020000. with description as "Port Disabled, Network Storm detected". Can you help with the solution for the same as I have a doubt regarding the description of this alarm given in help of control builder. It says "CEX bus fuse blown or missing". I am a little confused as some people told me its is because of Network loop from RNRP. For the information, we were trying to achieve the profibus redundancy at the media converter level. After that this problem has been observed.
