On the customer site, the issues 9206 and 26263 occurred randomly. [image] What exactly triggers the 26263 issue? Is it related to the RemMem setting? Specifically, if we allocate an excessive amount of Permanent memory, could it lead to the occurrence of 9206? Are there any other potential fact…

The retentive data (e.g. permanent and remanent PV) is stored in the SRAM. When the PLC is started, this data is copied to the PLC’s DRAM for speed reasons. In the event of a power fail, they are then copied back into the SRAM. In your case, your watchdog issue (9206) has prevented the data from b…

You could also change this behavior by backupping the data from DRAM differently. See following AS-Help online link Hardening measures: https://help.br-automation.com/#/en/4/automationruntime%2Ftargets%2Fsg4_gen%2Fremanentedaten%2Frem_error.html

Thank you, this gives an understanding of the 26263.
