Abstract

PURPOSE: To increase the responsibility without lowering the process effect to the computer by providing within the computer or the master transmission control unit the control memory and its corresponding data memory and then giving the commands to the control memory for the periodic transmission as well as the one- shot transmission.
CONSTITUTION: Both control ward memory CWM and data memory DTM are provided within master transmission control unit MS, so that the reading or writing is possible through both computer CMP and transmission control part TCU. Memory CWM and DTM are composed of the identical number of blocks each, and blocks COWCn within control memory are correlated with block DOWDn within data memory. At the same time, the transmission is carried out periodically by the command for periodical transmission set to memory CMD. The computer performs reading and writing of the input and output data when necessary to increase the process efficiency. Furthermore, the periodic transmission so far carried out is discontinued by the command of the one-shot transmission set to memory CMD, and the action designated by the block is carried out to enhance the responsibility
