Abstract

PURPOSE: To avoid the service deterioration for the ON-line data communication system by carrying out the maintenance test of the remote processor, the fault cut-off test of the circuit and terminal stored in the remote processor and the diagnosis test from the maintenance center and others.
CONSTITUTION: Circuit control adaptors 12W14 which connect terminal units 7W9 by the circuit unit plus processor 10 which is connected to adaptors 12W14 via bus 11 of the processor are provided to remote processor 3 in order to carry out the collection and distribution of the data between host computer 1 and units 7W9 as well as the interface matching. In such communication system, switching circuit 17 is provided to isolate processor 10 from bus 11 with the unit of adaptors 12W14 and thus to perform control. Furthermore test device 18 is added to perform various kinds of tests through maintenance terminal device 23. Device 18 is connected to adaptors 12W14 cut off from bus 11 via circuit 17 and actuated by the control of device 23 connected to processor 10.
