Abstract
Abstract A programmable controller (PC) for controlling equipments in accordance with a sequence program. A program memory is provided with an equipment code storage region for storing global equipment codes for indicating the equipments each of which is allotted an individual I/O address. When an equipment code is input, an equipment code interpreter determines the local I/O address which corresponds to the equipment code. The equipment code is composed of a PC number code, an equipment type code, an equipment number code and the like. The equipment code is displayed together with the sequence program.
