Hi all!
This is my first thread here (yay). I'll try to contribute to the Automation community as much as I can and I hope this forum can help me explaining the CLP fails for my Manager hahaha.
Here's the deal.. I got a ControlLogix using 1756-DHRIO to communicate with SLC500 remote racks. There was an 1746-NO4I card on one of the remotes which had nothing higher than 4mA on it's output... and in the MSG (Block Transfer) of that Output card there was an error (Error Code: 16#00CC Unknown error). Since the network and CPU and everything else was allright, we rebooted the DHRIO network (unplugged the network from the main DHRIO card) and then finaly the MSG error was gone and it started working back as usual.
Notes: Theres no schedule for the MSG routine.. it simply runs every scan like a regular routine... theres around 15 MSG routines in this CLP. I know this isnt the best but it has been working like this since the beginning of the project (6 years ago).
The only thing possible I see here is that happened a real quick network failure on the DH+ and when it recovered the MSG routine couldn't syncronize again due to it's lack of schedule.
Please someone help me on this theory
Also... I can't find anywhere what is Error Code 16#00CC
