MSB := Module Status Bits
Bit Offset Structure Member Data Type Description
0 Reserved BOOL Reserved
1 Reserved BOOL Reserved
2 Reserved BOOL Reserved
3 Reserved BOOL Reserved
4 Reserved BOOL Reserved
5 COM BOOL Communication
6 RUN BOOL Run
7 RDY BOOL Ready
 RDY (Ready)
When this bit is set, the module is operational. The RDY-Bit should always be set
by the module. If this bit is not set a system error has occurred and the
communication between controller and module is not possible.
 RUN (Run)
When the RUN-bit is set, the module is ready for communication. Otherwise an
initialization error or incorrect Parameterization occurs.
 COM (Communication)
When this bit is set, the communication is started and the module is engaged in
cyclic data exchange with the Master.
These three bits are the most important bits that the controller application can
use to monitor the communication and operating status of the module
Firmware Revision
This data field, which is part of the input image of the PROFIBUS Slave module,
will contain the current firmware revision. The Minor revision indication will be in
the low byte and the Major revision will be in the high byte. The Firmware Field is
placed in the Input area as shown in the following table.
Byte Offset Structure Member Data Type Description
4 FwMinor SINT Firmware Minor Revision
5 FwMajor SINT Firmware Major Revision
6-7 Reserved INT Reserved
Example:
If FwMajor = 10 and FwMinor = 1 then the firmware revision is 10.1.
