Explanation/Meaning
Transmission rate
Configured bus-cycle time; also defines the position controller cycle at the same time
configured time span for the cyclic data exchange within a PROFIBUS-DP cycle
Status of the configuration.
• Green lamp: DP-Master is powered up.
• Red lamp: Error function/no communication
Current bus status is shown in this field. Each bus status is explained briefly in the screen.
Possible states are:
• POWER_ON
• OFFLINE
• CLEAR
• OPERATE
• ERROR
Explanation/Meaning
Configured DP address of the DP slave
It is shown, 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.
Shows, whether the DP slave has been identified on the bus.
• Green lamp: DP slave was identified at the PROFIBUS-DP and the data exchange is working
with the assigned component (NC or PLC)
• Red lamp: Error function/no communication
It is shown, whether the DP slave is running synchronously to NC on the bus.
• Green lamp: DP slave runs synchronously to NC at PROFIBUS-DP i.e. the equidistant data
exchange takes place.
• Gray lamp: DP slave is not assigned to NC but instead to PLC.
• Red lamp: Error function/no communication
Number of configured slots within the DP slave
By pressing the button another diagnostic screen is opened, which contains the detailed
information for the respective DP slave.
