INTRODUCTION
WATCHDOG SECTION 5
The CX-10 watchdog timer may be used to reset the
CPU should modbus communication or program
execution stop. Watchdog timers are used primarily in
Basic programs.
Initially, a timeout value is set in register 30. Then the
program periodically writes a 0 to register 31.
Register 31 operates by incrementing once/second.
When its value equals that in register 30, the CPU will
reset. When the CPU resets, all relays are turned off and
all volatile integers and floats are erased.
