Programmable control system

摘要

A programmable control system for controlling a multiplicity of equipments by a plurality of programmable controllers (PC's) in parallel. Each PC is provided with a program linkage condition memory. The linkage conditions are the conditions for linking sequence programs to each other which are stored in the respective programmable controllers at the time of reading out the sequence programs in series. When a predetermined read command is issued, the sequence programs stored in the respective PC's are successively read out in accordance with the linkage conditions and are displayed on a display unit.
