Abstract
PURPOSE:To improve the efficiency of program generation by generating a program while considering a system composed of programmable controllers (PLC) to be one PLC. CONSTITUTION:Programmable controllers PLC1-PLCn store the same contents as to their programs and I/O data, and the I/O data variable according to controlled systems all the time are sent from a PLC having a change to all of other PLCs via bus every time when the change occurs or periodically, thereby holding the coincidence of the I/O data contents among the PLCs. Further, each PLC stores a program for a function that it takes partial charge of with another PLC and a program as a supervisor and the PLC normally operate while taking partial charge of the function, but any PLC is capable of performing the function of another PLC.
