CONSTITUTION:A central maintenance diagnostic computer 1 integrating a diagnostic program with respect to controllers 31-3n and connecting to a communication network 5, a test means testing the controllers 31-3n, an interactive means with a site maintenance personnel and a diagnostic auxiliary equipment 2 connected removably to the controllers 31-3n and connecting to the communication network 5 are provided. Then the diagnosis by the maintenance diagnostic computer 1 is attained by the diagnostic information obtained from the test means and the interactive means of the diagnosis auxiliary equipment 2 in response to the diagnostic command. Thus, the diagnostic information obtained by the intervention of the site maintenance personnel is collected from the site controllers 31-3n and the fault diagnosis with high accuracy is applied by the remote maintenance diagnostic computer 1. |
