DISTRIBUTED CONCURRENT PROCESSING PROGRAMMABLE LOGIC CONTROLLER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a distributed concurrent processing programmable logic controller system that can ensure the same function and performance as a large PLC by networking and operatively coordinating a plurality of small PLCs.;SOLUTION: The system, which organizes communication between a master station 1 and slave stations (11 to 17) and networks the slave stations (11 to 17) using a plurality of programmable logic controllers, has in the slave stations (11 to 17), memories (110 to 170) capable of monitoring communication between the master station 1 and the plurality of slave stations (11 to 17).;COPYRIGHT: (C)2005,JPO&NCIPI
