<p><P>PROBLEM TO BE SOLVED: To provide a detecting device of the abnormal operation in a rolling loop control system which is easily operable by anyone without necessitating technical knowledge of the connection circuit and the like in a rolling loop control system and with which the abnormal operation in the rolling loop control system is detected precisely and rapidly. <P>SOLUTION: This device is provided with a signal input part 11 by which the various kinds of electric signals outputted from the rolling loop control system 1 can be inputted in the block, a signal switching part 16 by which only specified electric signals can be selectively outputted, a signal controller 10A having an output part 14 for outputting the electric signals to the outside and a displayer 10B and a recorder 10C with which the output display and the output record of the electric signals outputted from the output part 14 of the signal control means 10A are made possible. In the case the abnormal operation happens in the rolling loop control system 1, places where the abnormal operation is caused are detected by reading signal data about the abnormal operation which are outputted to the displayer 10B and the recorder 10C. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
