Abstract
In a terminal control unit having a polling function to a plurality of terminal devices, the number of times of continuous non-response to the polling is counted for each terminal device address. If the number of times exceeds a predetermined number, a frequency of polling to that terminal device is lowered to eliminate unnecessary polling.
