Display Meaning/information
Status
Bus status POWER_ON (0): State after the control has been switched on
OFFLINE (1): Basic initialization has been performed
STOP (2): Start in accordance with the hardware configuration (SDB)
CLEAR (3): 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 (4): Cyclic data exchange with the PROFIBUS slaves running
ERROR (9): A fatal error had been detected (e.g. invalid or faulty SDB)
(<n>) corresponds to the OPI variable value for the bus state.
Bus configuration
S7 Subnet ID S7 Subnet ID of the PROFIBUS subnet
Baud rate Transmission rate in Mbd
Cycle time Configured bus cycle time in msec; also defines the position controller
cycle at the same time
Sync. Component (TDX) Configured time interval in msec for the cyclic data exchange within a
PROFIBUS DP cycle
PROFIBUS diagnostics/slaves
Slave address Configured number of the DP slave
Assignment 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)
Communication state Information whether the DP slave is identified on the bus via the commu‐
nication state.
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
Synchr. with NC Information whether the DP slave is running synchronously to NC on the
bus.
Green: DP slave runs synchronously to NC on the PROFIBUS DP, i.e.
there is an isochronous data exchange
Red: Incorrect response / no communication
Gray: DP slave is not assigned to the NC, but to the PLC
Number of slots Number of configured slots within the DP slave
