01
PROFIBUS proto-
col error
ON
Unit
The PROFIBUS Protocol error flag will be turned ON if an error has
occurred in the protocol handling, e.g. a transmitted token frame could
not be read back.
Note
In case this error occurs, the Unit will automatically switch to
OFF-LINE mode.
OFF
Unit
Indicates that no PROFIBUS protocol error has occurred.
02
Double Master
address error
ON
Unit
The Double Master Address error flag will be turned ON if there is
another master on the bus with the same with the same station address
as the CS1W-PRM21/CS1W-PRM21.
Note
In case this error occurs, the Unit will automatically switch to
OFF-LINE mode.
OFF
Unit
Indicates that no Double Master Address error has occurred.
03
Hardware error
ON
Unit
The Hardware error flag will be turned ON if an error has occurred on
the bus, e.g. message exceeding 256 bytes, broken messages, faulty
bus timing, or stations beyond the HSA have been detected.
Note
In case this error occurs, the Unit will automatically switch to
OFF-LINE mode.
OFF
Unit
Indicates that no Hardware error has occurred.

These bits will be set to OFF by the Unit.
12
Mode command
error
ON
Unit
This bit will be turned ON, if
• more than one command mode switch has been set, i.e. Bit 00 to
Bit 03 in Word n has been set, or
• a mode command switch is set while the previous command is in
progress, or
• a mode transition command is given and the Unit has detected that
it does not (yet) have a valid configuration or it detected an internal
error, either of which prevented it from reaching that mode, e.g.
Invalid Parameter set and transition to OPERATE mode.
If this bit is turned ON, it will remain so until a valid command is sent to
the Unit. The invalid mode command will be ignored.
OFF
Unit
If the bit flags have been cleared, the Unit will reset this bit to OFF.
13
Parameter error
ON
Unit
The Parameter set error will be turned to ON if an error has been
detected in the contents of the Parameters set while configuring the
PROFIBUS interface, using these parameters.
OFF
Unit
If the bit flags have been cleared, the Unit will reset this bit to OFF.
