Abstract

PURPOSE: To prevent sense information of an input-output equipment sending a unit check from being cleared in a data processing system with channels, by storing the unit check from the input-output equipment.
CONSTITUTION: Once input-output equipmwnt 3-i sends a unit check, unit check information is stored in subchannel memory 4-i of channel 2 and the generation of the unit check is reported to central processor 1-0. At this time, if another central processor 1-1 actuates input-output equipment 3-i, channel command word CCW is set to command register 5 and contents of subchannel memory 4-i are set to register 7. A command except a sense command resides in command register 5, OR circuit 11 is ON via decoder 6 while AND circuit 10 is ON, and sense information is prevented by this output from being cleared.
