How to Connect Pushbutton Switch to PLC

We will connect a lighted pushbutton switch to a programmable logic controller (PLC). Using our Click PLUS PLC, we will be assembling, wiring, programming, and testing our pushbutton switch system. The Fuji Electric pushbutton, normally open (NC) contact, will be wired to the first PLC (X1) input. The LED light will connect to the Click PLC (Y1) first output.
How to Connect Pushbutton Switch to Programmable ControllerFerrules will be discussed and demonstrated as a method of wiring any stranded wire. The use of ferrules applies to any automation devices with screw terminals. A ladder logic program will be developed to start and stop this lighted pushbutton light using just a single input. The output LED will turn on if the button is pressed for three seconds. Pressing the button again will turn the light off. This is the safest way of using one input to start and stop output. Let’s get started.

Productivity PLC Node-RED MQTT – P1000 / P2000

We will use an MQTT broker in Node-RED to communicate to the productivity PLC clients. MQTT stands for Message Queuing Telemetry Transport. This simple ‘publish and subscribe’ communication protocol does not take too many resources.
Constrained devices with low bandwidth are ideal for MQTT. This protocol provides machine-to-machine (M2M) connectivity, perfect for the Internet of Things. (IoT) This protocol is not for remote IO or real-time (deterministic) applications. MQTT is a good solution for applications that move data from hundreds or thousands of machines (sensors) to clients in many networks.
Productivity PLC Node-RED MQTT - P1000 / P2000We will be installing and programming the AEDES MQTT Broker in Node-RED. A productivity P2000, P1000, and Node-RED will be the clients communicating to the broker. The PLC simulator inputs on each controller will control the outputs on the other controller. This will demonstrate the communication capability for publishing and subscribing to this IoT platform. Let’s get started.
