Features

1

Here you can set whether the slave should continue to send data (Stay in Data Exch), even if it does not respond or respond erratically. In this case the data exchange remains active until the slave fails to respond correctly within the watchdog time (watchdog function is enabled, see Profibus tab of the slave). Otherwise the data exchange is not interrupted until the slave has responded incorrectly 65535 times.

2

Here you can specify whether the slave should restart automatically or remain in WaitPrm state, once it has exited the data exchange.

3

For each slave you can specify whether exit from Data Exch should lead to a stop of the PROFIBUS cycle (all slaves exit the data exchange and enter the WaitPrm state. A restart is only possible through an IO reset or restart of the TwinCAT system).

4

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.
