Title: Input/output transfer method for programmable controller
Inventor: KUDO KAZUHIKO
IPC: G05B19/05
Filed: 1989-06-27
Abstract: PURPOSE:To shorten the processing time or the I/O transfer by producing previously the input and output transfer control tables and performing the output transfer of a DMA controller and the input transfer of a CPU in parallel with each other. CONSTITUTION:A CPU 1 produces the I/O array information based on the attachment information on an actual I/O substrate and then produces the input and output transfer control tables based on the I/O array information to store it into a RAM 4. When the I/O transfer is started, the information on the output transfer control table is set to a DMA controller 2. Then an output transfer command is supplied to the controller 2 to start it. Thus the output transfer is successively carried out. At the same time, the CPU 1 repeats the reading of the information of the input transfer control table and the input transfer until the process is through with all contents of the table. Under such conditions, the controller 2 works in a cycle steal state to the CPU 1 and therefore the input transfer and the output transfer are processed in parallel with each other. Thus the processing speed is improved for the I/O transfer.
