Bug report for FbDigitalTwinMbSlaveDevice

CODESYS
1

Hello,

In my project, I am using the WagoAppPlcModbus 1.1.5.13 library on a PFC 200. Recently, I needed to establish communication with an A9MEM1541 energy counter via a PAS600L from Schneider. This device supports only paired word counts and accepts up to 100 registers; however, when attempting to read 95 registers, the counter returns an exception.

The issue arises in the FbDigitalTwinMbSlaveDevice function block: when the counter sends an exception, the PLC experiences an access violation and crashes.

Could you please submit a bug report and advise if a correction can be provided within a day?

Best regards,

If you have an urgent need and are sure you have clearly identified a bug in a library, I recommend reaching out directly to your local WAGO support office.
