Startup/Fault settings

1

The DP master changes automatically into the clear mode (the outputs of the slaves are set either to 0 or to the fail-safe value) when it ceases to receive an interrupt from the associated task (e.g. a PLC breakpoint has been reached, or the system has crashed). Here you can specify how many missing task cycles are tolerated before the master switches to Clear mode.

2

This button is used to set the DP watchdog for all DP slaves to an optimum value.

3

If the checkbox Set WD individually for each Slave is not ticked, the DP watchdog can be set to a uniform value for all slaves.

4

Here you can select whether the watchdog is to be set individually for each slave. If the checkbox is ticked, the watchdog can be set for each slave on the Profibus tab (see: Profibus).
