Parameterization and commissioning
Restart behavior
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 the Error Reactions [} 115] section).
Reaction of the master
For each slave you can specify whether its exit of Data Exch results in stopping of PROFIBUS cycle
(FC310x: all slaves exit the data exchange and switch to Wait-Prm, restart only through IO reset or restarting
of the TwinCAT system; EL6731: EL switches to PREOP state, restart through switching to OP state) (see
section Error Reactions [} 115]).
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 the Error Reactions [} 115] section).
acyclic services
The number of parallel ADS services to one box can be set here.

Firmware Update
This button enables updating of the firmware of a Beckhoff DP slave over a KS2000 cable via the serial port.
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)
