6.3.2 Adapter Watchdog Time, other Time Special Register (0x1020,
4128)
A watchdog timer can be configured for timeout periods up to 65535(1unit=100msec). The Watchdog timer
will timeout (timer decreased, reached 0) if ModBus operation to the slave node does not occur over the
configured watchdog value, then the slave adapter forces that slot output value is automatically set to
user-configured fault actions and values.
