Indicator lamps, solenoid valves, and motor starters (assemblies consisting of contactors and overload protection devices) are all examples of discrete control devices. In a manner similar to discrete inputs, a PLC connects to any number of different discrete final control devices through a discrete...
Backup and maintenance methods can make a real system very complicated. System scale A small PLC will have a fixed number of connections built in for inputs and outputs. Typically, expansions are available if the base model does not have enough I/O. PLCs used in larger I/O systems may ...
Examples of discrete output devices are lights, relays and motor starters. From our dishwasher example inPart 1, some of the discrete inputs would the start button, the door switch and the water level switch. Some of the discrete outputs would be the water fill valve, the water drain ...
It combines graphic and text editing capabilities, so both diagrams and corresponding inputs and outputs can be entered. As the editor is more dedicated to FBD language, pure LD diagrams should rather be entered using AC31GRAF Quick LD editor. 4.1.1 Basics of the FBD/LD languages The FBD ...
