8.3.2. 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.

MODBUS/TCP connection timeout time. (0.5sec unit)
Maximum time of ModBus connection to stay to be opened
without receiving a ModBus request. 0~3600 The 120
(60sec) is default value.
The value 0 disables connection time out specially.
*Notice : When using Ethernet/IP only, this value should be ‘0’
(disable).

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
