<p>PURPOSE: To improve the exactness of supervisory by ignoring a pulse integrated value under correcting at a master station when this pulse integrated value is corrected at a slave station. CONSTITUTION: At a slave station 1, an integrated value correcting means 36 corrects the pulse integrated value, under-correction reporting means 33-37 turn on an under-pulse-correction flag during the time when this integrated value correcting means 36 is correcting the pulse integrated value, and the under-pulse-correction flag and the pulse integrated value are paired and reported to a master station 3. When the under-pulse-correction flag in ON-state is reported from the under-correction reporting means 33-37, at the master station 3, an under-correction output stopping means 43 stops the output of a pulse signal.</p> |
