NoAnswer-Reaction : You can specify, for each slave, whether it should remain in the Data Exch, despite
responding incorrectly or not at all. In this case (Stay in Data-Exch), data exchange is only exited if the slave
has never responded correctly within the address monitoring time (provided the
watchdog (see the box's
Profibus [
}
58] tab) is activated, otherwise data exchange is only terminated once the slave has not
responded correctly 65535 times) (see the Error Reactions [
}
16] chapter).
Restart-Behaviour : It is possible to specify for each slave whether, after leaving Data-Exch, it should
automatically start up again, or should remain in the Wait-Prm state (see chapter Error Reactions [
}
16] ).
Reaction of the Master : You can specify for each slave, whether its exit from Data-Exch should cause the
PROFIBUS cycle to stop (all slaves abandon data exchange and go into Wait Prm mode, restart after IO
reset or TwinCAT system restart) (see chapter
Error Reactions [ } 16] ).
Changes of the Input Data : For each slave it can be specified whether, on exiting of Data Exch (DpState
not equal 0), its input data should be set to 0 or remain unchanged (see chapter Error Reactions [
}
16] ).
acyclic Services : The number of parallel ADS services to one box can be set here.

FirmwareUpdate : This button enables updating of the firmware of a Beckhoff DP slave over a KS2000 cable
via the serial interface
2 byte PLC interface : Switches on the 2 byte PLC interface of the Beckhoff DP slave.
Synchron K-Bus-Update : For Bus Couplers, the expected internal cycle time (K-bus cycle + DP buffer
transfer) is specified here.
Check Terminals during Start-Up : If this checkbox is activated, table 9 is transferred to the coupler by
means of DPV1 write, and the coupler only enters data exchange (DpState = 0) if the entries agree. This
makes it possible to check the terminals more precisely when starting up than is done with PROFIBUS
CfgData.
K-Bus Error : It is possible to specify the reaction to a K-bus error here (automatic or manual K-bus reset,
reaction in the input data in the coupler)
