Retain data shall be saved automatically during a warm start

andrey007

Hello everyone,

I have found out that the retain data is saved automatically during a cold start. After a power failure, the AXC 2152 performs a warm start.

Therefore, my retain data should also be saved automatically during a warm start (as it can also be done manually in the WBM or in Plcnext Engineer).

Do you have any suggestions on how I can solve this problem?

Hello Andrey,

In my case, the data is saved after a warm start.

-PLCnext Engineer 2024.6

-AXC F 2152 2024.6.0

Maybe this will help you: Known issues

Thanks for the hint, but I would like to save the retain data as a file in the retaining folder (as it is also possible in Plcnext Engineer).

I have already found a solution. I created a new library with the Plcnext toolchain and use the API:

https://api.plcnext.help/api_docs_2022-6/classArp_1_1Plc_1_1Retain_1_1Services_1_1IRetainManagerService.html

Then I created a warm start event task that will execute the library.
