Meaning
Before a station number can be changed, the corresponding
station number must be configured with COM ET 200
Windows.
The DP slave must be physically present and connected to
the SINEC L2 DP bus.
DP slave has responded with incorrect data; the CS command
has not been processed by the DP slave.
Repeat the function FCT = CS. If the error message persists,
check the DP slave.
DP slave has responded with incorrect data; the CS command
has not been processed by the DP slave.
Repeat the function FCT = CS. If the error message persists,
check the DP slave.
DP slave has responded with incorrect data; the CS command
has not been processed by the DP slave.
Repeat the function FCT = CS. If the error message persists,
check the DP slave.
DP slave unable to implement station number change;
corresponding SAP not available to DP slave.
The control command specified in the GCGR parameter is
still being processed. Do not process the input/outputs
affected by this command.
Repeat the FCT = CC.
If you require consistent diagnostic data, call the FB IM308C
again.
If you do not require consistent diagnostic data, you can read
the inconsistent diagnostic data from the specified target area.
Repeat the function call.
The IM 308-C failed to send a feedback message to the
FB IM308C after function implementation.
