I have a question. I work in a very large plant and this one (of many hundreds of control cabinets) contains one 5580 (1756-L83E), two 1756-L73 and seven 1756-EN2T in the 16 slot rack. The controller in question here is the 5580 (1756-L83E). It is having thousands of minor faults per second. I know what the cause of the repetitive (T:04 C:51) fault is. It is due to some data being pushed into a specific index of an array that is a few characters over sized. I will be fixing it, but I'm doing a little RCA here and trying to determine if it may be reasonable to assume those thousands of faults could be responsible for the primary EN2T module (acting as the host connection to a cloud service) randomly losing communications to said cloud service? This is a 24/7 operation and it has happened about 5 times (at least) over the last 5 months causing significant downtime each time (hour, to a few hours). Only recently did I notice all the minor faults, but I traced it back to have started happening about 6 months ago when someone made some logic changes that began overflowing the array index. I know how the logic functions would obviously play a role in this, but I'm just wondering if anyone might agree that these thousands of faults occurring steadily 24/7 could possibly, randomly cause the network issues we're experiencing. Like in combination with allll the other processing this controller is constantly doing. I will be fixing the logic, but someone else wants me to replace the EN2T module tomorrow morning, so I am going to wait a while to fix the logic to determine if it is the module or the faults. Just wondering if anyone might think my theory could be very likely. Also, the network cables and switches and all other devices from inside the panel and out appear to be just fine and IT ran traces on the lines with their fancy little network analyzer meter tool and determined they see no issues (between both the current line/port being used as well as the spare unused emergency line/port right next to it).
