You can read the status of the license from your application through the CmpCodeMeter library.

See https://forge.codesys.com/forge/talk/Runtime/thread/1c1b00cfc7/

So the code could be something like (change the numbers according to the licenses you are searching for):

VAR
    // add CmpCodeMeter library
    xCheckLicense: BOOL;
    xFound: BOOL;
    Handle: CmpCodeMeter.RTS_IEC_HANDLE;
    Result: CmpCodeMeter.RTS_IEC_RESULT;
END_VAR

// check for valid Raspberry Pi license
IF xCheckLicense THEN
    xCheckLicense := FALSE;
    xFound := FALSE;
    Handle:= CmpCodeMeter.CodeMOpen(udiFirmCode := 5000304, udiProductCode := 603001, udiFeatureCode := 16#1, Result := Result);
    IF Handle <> CmpCodeMeter.SysTypes.RTS_INVALID_HANDLE AND Result = CmpCodeMeter.Errors.ERR_OK THEN
        xFound := TRUE;
        CmpCodeMeter.CodeMClose(hCodeMeter := Handle);
    END_IF
END_IF

I'd like to monitor CODESYS licences used in my automation solution, in particular the runtime licence and the soft motion licence.
My need is to rise two alarms on the HMI system in case such licences are missing.
Is that possible ? Could someone suggest a way in order to get that working?

Best regards
Rossano
