Programmable logic controller and program generation device for generating a sequence program for a programmable logic controller

摘要

Programmable logic controller (plc) for the execution of a control program for a sequence of processing, wherein on the bits - data is accessed by a plurality of addresses in the physical memory or an i / o - memory area are specified, wherein the programmable logic - controller comprises:a processor (11) and an address conversion of a unit (70, 80), which is designed in such a way that,if the processor (11) to a predetermined address which an address conversion unit (70, 80) to the large number of bit data at a plurality of different addresses in the physical memory or an i / o - memory area, and these bit data accesses to the processor (11) under the predetermined address available.
