This register restarts the watchdog timer by writing a value of 0x1 into it.
If the watchdog was stopped before the overrun, it is not restarted.

Simply stop watchdog, WD_AC_STOP_SIMPLE
Read/write
0x0000
This register stops the watchdog by writing the value 0xAA55 or 0x55AA into it.
The watchdog timeout fault is deactivated and it is possible to write in the
watchdog register again. If there is an existing watchdog fault, it is reset

Alternative watchdog
Read/write
0x0000
This register provides an alternate way to activate the watchdog timer.
Procedure: Write a time value in register 0x1000; then write a 0x0001 into
register 0x100A. With the first MODBUS request, the watchdog is started. The
watchdog timer is reset with each MODBUS/TCP instruction. If the watchdog
times out, all outputs are set to zero. The outputs will become operational again,
after communications are re-established.
Register 0x00A is non-volatile, including register 0x1000.
It is not possible to modify the time value in register 0x1000 while the watchdog is
running.
