<p>PURPOSE:To allow the execution of monitor display of data changing at high periods without trouble by enabling setting of a sampling period at every data of respective external devices thereby making the refresh display even with a monitor screen of many data items according to the sampling period. CONSTITUTION:The sampling periods when the data from the external devices are inputted are registered each of the data of the external devices by input device 5 and are stored in a memory 3 at the time of monitor registration. The data of the respective external devices are inputted from an interface device 6 and are displayed on a display device 4 in accordance with the sampling period of each of the data stored in the memory 3 at the time of monitor execution. The data changing at a high speed are subjected to high-speed refreshing according to the setting of the monitor sampling period of a high period and the data changing at a low speed are subjected to low-speed refreshing according to the setting of the monitor sampling period of a low period. The monitor display of the data changing at a high speed is surely executed in this way even if the number of data items increases.</p> |
