Abstract

PURPOSE:To increase the efficiency of the data transfer, by carrying out via a data bus line the data transfer of a system including a terminal device having the emergency or a terminal device having no emergency by means of an interrupting function to a bus controller. CONSTITUTION:An inerruption request detecting circuit 32 connected to an isolation transformer 39 detects an interruption request and then decide the type of the request. Thus an interruption vector corresponding to the above-mentioned decisin is delivered to a parallel line A2 for interruption vector signal and then informed to a controller 36 via a received signal line A1. The controller 36 discontinues the present data transfer based on the interruption vector or applies an interruption to a digital computer 37 to quickly start a process for the received request for interruption.
