摘要
A method for operating a programmable logic controller (PLC), and a programmable logic controller (PLC) for a processing plant with a central data processing unit and a sequence control that reads in, processes input data from inputs, and outputs the processed output data to outputs. The data processing unit performs only superordinate administrative functions for the administration of downstream input and output modules and is embodied as an ADMIN data processing unit. The sequence control is embodied as a partial application autonomously executing in the input and output modules.
