PLS

Processcontrolsystem: IT system for supporting production processes with a focus on process engineering operations, e.g. in a large-scale chemical plant. The functionality essentially comprises open-loop and closed-loop control functions for components of the plant (e.g. actuators/controllers), data acquisition in real time (e.g. from sensors including visualization for the operator) and alarm functions. Furthermore, they usually also enable storage of the acquired data and offer additional evaluation functions. In Anglo-Saxon countries, the systems are often referred to as DCS (distributed control system) or PCS (process control system).
