<p>PURPOSE:To lighten the processing load of an alarm register data producing part and to shorten the time for rewriting an alarm displaying buffer memory by allowing the alarm register data producing part to produce editing data when the data is rewrited, and sending it to an alarm control part through a mail box. CONSTITUTION:When the data rewriting is instructed, the alarm register data producing part 4 produces the editing data for the rewriting and sends it to the mail box 1. The alarm control part 6 receives the edited data from the mail box 10 and rewrites the alarm displaying buffer memory 7. Thus, when the data is rewrited, the alarm register data producing part only rewrites the alarm register data memory, whereby its processing time can be shortened, and it can immediately prepares for an input from a keyboard.</p> |
