Abstract

PURPOSE:To efficiently recover a trouble passing a longer time by several digits than the ordinary processing of the time out of a program by constituting a processing system of a channel device which can detect an abnormality according to a time monitor and informing the abnormality to the program at the time of detecting the abnormality. CONSTITUTION:The format of limited channel log out (LCL) information is constituted of many types of bits, the bit 26 thereof is the information indicating the detection of the time out and information indicating the 'detection of the time out' is newly added herein. The channel device 20 monitors a response time fed from an I/O 21 through an I/O interface 22, this operation is executed in a time out detecting circuit 23 in the device 20 and when there is no response from the I/O 21 within a specified time,the output of the bit 26 is set to '1' and set to the bit 26 of an LCL 25. The output 26 is latched to a channel status byte 24 through an OR circuit and this output and the LCL are together informed to the program.
