Abstract
A programmable controller which handles both bit data and word data includes a memory having a memory area which is divided into blocks each having a predetermined length which corresponds to the number of bits constituting one word. An address is provided to each of the blocks, and one bit data or one word data is selectively stored in each of the blocks. Thus, the memory area is provided with flexibility, and the preparation of a program is facilitated.
