Reset error attribute values

During execution of the UCO, the object might encounter an error. Some examples are:

• The quality of the input sources for a Raw Reason Code is not good

• The quality of production attributes are not good

• The MES middleware is not responding

• The MES API call returns an error back to the UCO

Depending on the error, the UCO might transition into an error condition. If it does, the Status attribute will be Error and the appropriate error code and error message will be updated. Once in an error state, the UCO will not accept a new command until the error is cleared.

To clear the Error status, the Reset command must be set. This will reset the status to Ready, clear out all error code and error message properties, and reset all command attributes to False. Certain errors such as bad quality of I/O inputs will log an error to the Logger, but the UCO will remain in a Ready state as these might be temporary issues with the I/O and do not indicate a failure of the UCO.
