Process automation device, has central processing unit and master device with memory linked to slave devices e.g. actuators, sensors

摘要

A memory-programmable control device (10) in an automating device (9) has a battery buffer (11) for supplying suitable voltage/current needed for operating components to a set of CPU components (12), master components (MC) (13) and functional/memory components. The MC have a memory (14) with input (PE) and output (PA) data ranges for process computer peripherals.
