Abstract

PURPOSE:To facilitate the rewriting of the control program of a controller by directly accessing a memory in a controller other than one to which an input and output equipment is connected through a control line and a bus. CONSTITUTION:Scanning type programmable controllers #1 and #2 are linked to each other through a bus B for input and output data transfer and a control line ; the controller #1 connects with a control program input and output equipment PC and is provided with a synchronizing signal generator P separately. By a routine in a period D1, the programmable controller 1 and 2 scan input and output data and by a routine in a period D2 after it, the controller-to-controller transfer processing of the input and output data is performed. By a routine in a period D3 after it, the said input and output equipment PC is connected substantially to secure the time when operation is performed.
