MsgFilter: Bit 1 Diagnosis Messages

The hardware provides an internal message logger that logs error-dependent controller deactivations. The next time the controller is started, the error logger is analyzed, and the cause of the error can be given in the message logger. In addition, a more specific message is indicated (8055 Controller message HW monitor) that can be enabled by the MsgFilter parameter and activated via the Logic Builder message logger.
