Traffic Light in Multisim using PLC
Programmable Logic Devices (PLDs) are integrated circuits that contain a relatively small number of functional elements that provide user-configurable logic functions (AND, OR, etc.)
In Multisim a PLD schematic contains specialized components that define the operation of the individual logic blocks of the PLD.
What is PLC and PLD?
The biggest difference between the two is the control logic. PLC is a fixed logic device (the function is realized by changing the software), and PLD is a variable logic device (the function is realized by changing the internal circuit structure).
The concepts of PLC and PLD can be practiced through this two-way traffic light example. The main implementation of traffic light signals in to avoid traffic jams and serves the purpose of avoiding vehicular collisions.
The ladder diagram in this blog runs two traffic lights. The ladder diagram is contained in a separate hierarchical block called TrafficLightLogicThere are two different traffic light examples available, look in the
