Profibus Address
The actual Profibus address of the selected slave is shown in the address selection box. Only
available addresses are listed and can be selected as new address.
Watchdog
According to the Profibus specification, a slave device may be configured with a watchdog
function such that the master must poll the slave within a defined interval. If this feature is
enabled and the master fails, the slaves watchdog timer will timeout and the slave will reset
itself.
Group Assignment
If the slave supports sync/freeze functionality, it can be assigned to the masters sync/freeze
groups by clicking on the checkboxes. The sync/freeze assignment of the groups is also
displayed (these can be changed via the master properties dialog).
