Abstract

PURPOSE:To prevent interruption of processing due to forgetting of channel mounting when a processing system is operated, by sending I/O instructions to individual I/Os and searching control channel numbers of no response to enter them in an I/O management table. CONSTITUTION:Before the system is operated, an I/O control program 11 is executed. Then, a processing part 8 sets flag ''1'' in the term of a chennel number C1 of a column L2 in a table T by a response signal D1 from a control channel CH1 of a mounted printed board, and a register 12 is updated. A processing part 7 issues a read instruction R2 to a channel CH2 on the basis of an updated address A1 of the register 12. If a printed board PT2 is not mounted, the response is not transmitted from the channel CH2. A monitor part 13 sends a no-response signal D2 to the processing part 8 after a prescribed time and sets flag ''0'' in the term of a channel number C2 of the column L2 in the table, and the register 12 is updated. After this control, flags indicating whether printed boards are mounted or not are set in terms of channel numbers C1-Cn of the table T.

After referring to the pointer section 6 (in which pointer P2 is stored) of the monitoring section 13, the response signal D] is sent to the table processing section 8. Based on this response signal D], the table processing unit 8 sets a flag "1" in the column of the channel number C1 of l'J]Lz of the table T. After completing the flag setting, the table processing section 8 then sends the control signal F to the addition section 14 to add (AO+1-+A1) to the data (Ao) in the register 12, and send the obtained A] to the register 12. send it to update its value. Further, a control signal F is sent to the processing unit 7 to notify that the flag setting has been completed. Based on the address data A1 in the register 12, the processing unit 7 takes out the data at the address A] of the memory 10, that is, a read command R22, and issues this to the control channel CH2 via the bus Bti. As mentioned above, printed board PT2
