Abstract

PURPOSE:To cause all devices to receive a rapid service uniformly, by dividing data, which is generated from the data generation source, by a prescribed volume and by switching transfer destination devices each time when the divided prescribed volume of data is transferred. CONSTITUTION:A unit transfer volume of data which is queued in the data pointer in the device control block DCB indicated by the indicator CSI of the station control block SCB is transmitted to a corresponding device by one access. Then, when the response from the device for this transmitted unit data is received, the address of the block DCB indicated by the next pointer of this block DCB is stored in the indicator CSI. When the next pointer indicates the end after repeating this processing, the start address of blocks DCB which is stored in the block DCB terminal is stored in the indicator CSI, and the similar processing is performed again.
