3.2.3. 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.
Address Access Type, Size Description
0x1020(4128) Read/Write 1word Watchdog time value 16bit unsigned.
The time value is represented by multiples of 100msec.
The 0 (watchdog timeout disabled) is default value.
A changing of watchdog time value resets watchdog error and counter.
0x1021(4129) Read 1word Watchdog timer remain value
This value is decreased every 100msec
