PROGRAMMABLE LOGIC CONTROLLER AND OPERATING SYSTEM FOR VIRTUAL PROGRAMMABLE LOGIC CONTROLLER AND COMPUTER PROGRAM PRODUCT

摘要

The present invention relates to a programmable logic controller, a method for operating a programmable logic controller and a computer program product. In particular, the invention relates to a programmable logic controller and an operating method for a programmable logic controller for the parallel operation of a plurality of PLC applications on a programmable logic controller. A programmable logic controller (2) has: a data processing unit (4), at least one input (10), at least one output (20), at least one memory area (8a) for application programs, the programmable logic controller (2) being set up during operation using an operating system to provide at least one virtual programmable logic controller (30a) on which an application program can run.
