Hello! I am hoping someone can help me with an issue I am encountering. My company recently purchased a new MES system (Critical Manufacturing) and along with it we purchased Kepware in order to bridge the gap between machine and MES. Here is the scenario:
I have a machine with an Allen Bradley CompactLogix 5380 controller (5069-L320ERMS2/B) with firmware version 32.012 installed. I am using KEPServerEX to connect to the AB controller using OPC-UA protocol. I have a fully populated list of machine tags presented to me (around 34,000 tags in total) and I am able to view the real data on these tags when opening the OPC Quick Client to view them. I have successfully performed read operations on all of the relevant tags I need, so I know the communication is working in that direction - the issue is when I try to write data to the tags. I have boolean tags in the PLC that correlate to certain functions, such as counter resets. I have attemped both Synchronous Writes and Asynchronous Writes to the tags, but I immediately fail each time (see screenshot of logfile attached).
I am hoping someone can shine some light on this issue for me. I am not an experienced controls engineer, and this is really my first experience working with PLC language, Kepware, etc... Any help would be greatly appreciated!
**added a couple of additional screenshots showing the tag names, and the tag properties in Kepware. Additionally in the TagProperties screenshot you can see the error codes being written in the background - this is from the MES system trying to send the tag updates and failing.
