<p><P>PROBLEM TO BE SOLVED: To provide a duplex field control device for smoothly switching control authority. <P>SOLUTION: An update control means 23 of a CPU 2B determines whether or not a timer clock (Tick) of a CPU 2A is faster than the timer clock (Tick) of a CPU 2B. When the determination result is affirmative, time count processing for the next timer clock (Tick) is bypassed, and when the determination result is negative, an application clock 21a is updated by time count processing. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
