Querying the current bus status
Code
C13861 displays the current PROFIBUS status in a bit-coded form:
Bit assignment Description
Bit 3 Bit 2 Bit 1 Bit 0 Reserved
Bit 5 Bit 4 Status of the DP state machine (DP-STATE)
0 0 WAIT_PRM The slave waits for a parameter data telegram after
acceleration. Other types of telegrams will not be processed.
Data exchange is not yet possible.
0 1 WAIT_CFG The slave waits for the configuration telegram that specifies
the number of input and output bytes. The master informs
the slave about the number of I/O bytes that will be
transferred.
1 0 DATA_EXCH If the parameter settings as well as the configuration have
been accepted by the firmware and by the application, the
slave state changes to DATA_EXCH ("Data Exchange",
exchange of user data with the master).
1 1 Not possible
Bit 7 Bit 6 Status of the watchdog state machine (WD-STATE)
0 0 BAUD_SEARCH The PROFIBUS slave is able to automatically detect the baud
rate.
0 1 BAUD_CONTROL After recognising the correct baud rate, the slave status
changes to BAUD_CONTROL and the baud rate is monitored.
1 0 DP_CONTROL The DP_CONTROL status serves for response monitoring of
the master.
