Abstract
The programmable controller composed of a main body unit and a plurality of input/output extension blocks is provided with type identifying means for identifying the number of input output points and present organization storing means. Upon receiving an organization update instruction signal, it can allocate input and output numbers in various ways by rewrite setting means in a system memory and can select a second allocation method with which existing input and output numbers are not changed or a first allocation method with which input and output numbers are completely changed anew. When input and output numbers are completely changed anew, it can automatically change input and output numbers accompanying an instruction in a program memory by instruction changing means in the system memory.
