Function/Part function Explanation/Meaning
Bus-configuration
Baudrate in MBd Transmission rate
Cycle time in msec Configured bus-cycle time; also defines the position controller cycle at the same time
Synchronous part (TDX)
in msec
configured time span for the cyclic data exchange within a PROFIBUS-DP cycle
Status
Configuration ok Status of the configuration.
• Green lamp: DP-Master is powered up.
• Red lamp: Error function/no communication

Table 5-2 Diagnostic screen Information about slaves
Function/Part function Explanation/Meaning
Slave no. (DP address) Configured DP address of the DP slave
Assignment 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.
active on the bus 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
Synchr. with NC 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 slots Number of configured slots within the DP slave
Details By pressing the button another diagnostic screen is opened, which contains the detailed
