Abstract

PURPOSE:To make the connection between i/O module units unncessary, by handling the information of input and output element shared by other controller the same as the information of the input and output element shared by the controller itself. CONSTITUTION:An input and output unit 21 connected to input and output elements MTINj, MTOUTj of machine side MTj is connected to a data memory 27 via an interface 22. An input and output data representing the status of the input and output element group MTINi and MTOUTi shared by a programmable sequence controller PCi is given to a memory area M.AREi of the data memory 27 from a dara bus line DATBS by a data transfer unit 28 and an input and output data respresenting the state of the input and output element group MTINj, MTOUTj shared by the PCj stored in the memory area M.AREj is transmitted via a data bus line DATBS so that it can be stored in the memory area of other PCNs.
