ABSTRACT:
A memory programmable control with a processing unit, a program memory, input modules and output modules in which a memory is provided for storing a process image which is renewed in every processing cycle. The process image is an image of the signal states of the initial states of the inputs and outputs. During the processing of a control program, the processing unit does not work with the input and output modules, but exclusively with the process image. This increases the processing speed and prevents flutter of the outputs.
