Abstract
In a programmable controller linking system, a plurality of programmable controllers are connected to one master controller and sequences of the programmable controllers are programmed using addresses representing optional input/output memory areas. Link tables are prepared by automatically allotting input/output memory areas of the programmable controllers, to the inner relays, with respect to addresses of the respective programmable controllers except for the subject programmable controller, the thus prepared link tables are registered in the master controller, and all the link tables are collected from the respective programmable controllers in the master controller at the link starting time to prepare an editorial link table by collecting common portions of the collected link tables. The input/output side address tables are provided for the master controller and for the respective programmable controllers so that the data is periodically accessed and linked between the master controller and the respective programmable controllers in accordance with the input/output side address tables.
