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. **added a couple of additional screenshots showing the tag names, and the tag properties in Kepware. 0 Description Customer alert and recommendations for remediation of the Apache log4j 2.x identified vulnerabilities CVE-2021-44228 and CVE 2021-45046.
KEPWARE SECURITY PATCHES SOFTWARE
I am not an experienced controls engineer, and this is really my first experience working with PLC language, Kepware, etc. KEPServerEX provides data access for client applications (such as MES and SCADA) and IoT and Big Data analytics software via OPC, proprietary protocols (including GE NIO, SuiteLink/FastDDE, and Splunk), IT protocols (including MQTT, REST, ODBC, and SNMP), and flow measurement export to common Oil & Gas industry formats. I am hoping someone can shine some light on this issue for me. I have attemped both Synchronous Writes and Asynchronous Writes to the tags, but I immediately fail each time (see screenshot of logfile attached). I have boolean tags in the PLC that correlate to certain functions, such as counter resets. 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 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 am using KEPServerEX to connect to the AB controller using OPC-UA protocol.

I have a machine with an Allen Bradley CompactLogix 5380 controller (5069-元20ERMS2/B) with firmware version 32.012 installed. 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.
