[ISS Support Case] RDI Tags Failing to Update or become stuck in initializing status

Last updated: October 17th, 2025

Description

Specific tags located under one PLC are not auto updating with communication data. The quality is showing as good, but these tags seem to only update throughout the system when the graphic where the object is linked to the tag is opened. Otherwise the values do not seem to update. This is an issue because there are Batch process's that depend on the information contained within these tags to initialize the Batch. I tried having the client set the scan group in the DDESuitlink object for these tags to ActiveAll and redeploy, but this does not seem to have had any effect. I also did notice the clients system is under resourced in regards to the logical cores by about 4-6 cores. They are going to address this in a down window. They may be able to do this at 2 pm EST today so I am looking for a meeting at that time if possible to work on diagnosing the issue should the additional system resources not rectify the issue.
