SIWAREXWP231: WP321DRS explanation w_ErrorCode

I use the WP321S block from the "Ready-for-use" project.The small block does not read the DR32 data record.Therefore, there are no faults in DR32.OPERATION_ERRORS or .DR32.TECHNOLOGICAL_ERRORS.It is possible to use w_ErrorCode in the WP321S DB.Is its meaning described somewhere?

Thank you.

Thank you for your response. I didn't notice the s_IO_DATA.ERROR_CODE variable.

But I also did not find a description of this variable. Both variables remain 0. I disconnect the cells, SIWAREX reports an error. In Siwatool I see errors 1106 Load cell underload or 1104 ADC sens voltage too low. ERROR_CODE is equal to 0.

Thank you.
