Abstract

PURPOSE:To improve the processing efficiency of the titled control system by shortening the interruption processing time in case a channel device gives a processing request to a channel processor and at the same time reducing the processing sequence between the channel device and the channel processor. CONSTITUTION:The processing sequence set between a channel device CH and a channel processor CHP can be finished by an answer given to the CHP from the CH and vice versa. While both an interruption request and the interruption contents are transmitted at one time and an answer of the CHP is waited for with the interruption processing given to the CHP from the CH. Thus the interruption processing time is shortened when a processing request is given to the CHP from the CH. At the same time, the processing sequence is reduced between the CH and the CHP and the processing efficiency is improved.
