Title:
LINK OPERATION UNIT APPARATUS AND METHOD OF DETECTING ERRONEOUS STATION SETTING FOR THE SAME
Document Type and Number:
Japanese Patent JP3854251
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a link operation unit apparatus by which erroneous station setting for a plurality of sets of unit apparatuses is easily and exactly detected.
SOLUTION: In supplying a power source, predetermined fixed timer timing is counted by means of a fixed timer 23. In the course of counting the fixed timer timing, random timing shorter than the fixed timer timing is counted by means of a random timer 25. Upon completing the random timing counting by means of the random timer 25, a confirmation signal transmission means 27 transmits a confirmation signal to other unit apparatus. At the point of time when the counting of the constant timer timing is completed by means of the fixed timer 23, a station setting error determination means 29 determines that an error is present in the station setting, when the confirmation signal is received from the other unit apparatus. Furthermore, at the point of time when the counting of the constant timer timing is completed by means of the constant timer 23, the station setting error determination means 29 determines that no error is present in the station setting, when no confirmation is received from the other apparatus.
