Meaning/information
Status of the configuration
Green: DP master has ramped up
Red: Incorrect response / no communication
POWER ON: Status after the controller is switched on.
OFFLINE: Basic initialization has been performed.
STOP: Start in accordance with the hardware configuration (SDB).
CLEAR: PROFIBUS slaves have been parameterized and configured in
accordance with the hardware configuration (SDB) and taken into the
cyclic data exchange with zero output data.
OPERATE: Cyclic data exchange with the PROFIBUS slaves running.
ERROR: A fatal error had been detected (e.g. invalid or faulty SDB)
Transmission rate
Configured bus-cycle time; also defines the position controller cycle at
the same time
Configured period for the cyclic data exchange within a PROFIBUS DP
cycle
Configured DP address of the DP slave
Information whether the DP slave is assigned to the NC or to the PLC
NC: E.g. one or more drives controlled by the NC.
PLC: e.g. I/O peripherals or an axis controlled by the PLC.
NC/PLC (for DP integrated)
Information whether the DP slave is identified on the bus
Green: DP slave has been detected on the PROFIBUS DP and the
data exchange is working error-free with the assigned component (NC
and/or PLC)
Red: Incorrect response / no communication
