Abstract

PURPOSE:To evade setting based on a manual and to automate with the constitution of a device by automatically recognizing and setting a transfer system set between the facing devices by means of a microprogram. CONSTITUTION:By a transfer system instructing signal 8 to be the output of a transfer system setting means 5, an interface control means 4, which supports the plural transfer systems, selects and determines a single transfer system. In the transfer system of a determined input/output interface 3, an interface deciding means 6 actually activates the data transfer at the section of a lower- order device 2 for an interface control means 7 by a data transfer instructing signal 9, and decides the normality or abnormality of a transfer result through a signal 10 to be a transfer result deciding factor. Thus the input/output interface 3 successively tests the supporting transfer systems, and when the transfer result is decided to be normal, the transfer system specified at the section of the lower-order device can be recognized and determined.
