The ModBus operator supports fieldbus supervising. Two operator parameters configure
this function. Watchdog_Inhibit defines several events that reset the fieldbus watchdog.
Watchdog_Activation serves for activating the watchdog functions with the first
occurence of certain events. The effect of the timeout of the Watchdog timer is adjusted
via parameter Pn.05. Parameter Pn.6 determines the Watchdog time. For more information
see parameter description below and in the application manual of the used inverter
control.
