PURPOSE:To make it possible to grasp precisely a fault of a system and its activity state by sending a call connection request by installing in a specific decentralized processor a testing equipment equipped with a terminal function as a testing artificial terminal. CONSTITUTION:In every constant period, testing equipment TSE202 sends a connection request to testing procedure unit 208 installed in each decentralized processor 203 to test units 203 constituting the system. Namely, if each decentralized processor where the connection request has been sent would not be connected well as many times as fixed within a certain time, TSE202 judges that some fault is occurring, thereby analyzing the result. Therefore, TSE202 can judge a system fault when requested connections to all decentralized processors can not be made well or a decentralized-processor fault in other cases. Consequently, the falut of the system and the activity state of each unit can be grasped with precision. |
