Master PLC Wiring: Safe Single-Button Start/Stop Control

We will connect a lighted pushbutton switch to a programmable logic controller (PLC). Using our Click PLUS PLC, we will assemble, wire, program, and test 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. Ferrules will be discussed and demonstrated as a method of wiring any stranded wire. Ferrules are used with any automation device that has 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 to use a single input to start and stop the output. Let's get started. More information can be obtained at our Website.

This simplicity makes CLICK a perfect solution for small machines, home automation projects, pneumatic applications, or anywhere a simple system needs a budget-saving control solution. Building on the original CLICK’s simple design, the new CLICK PLUS PLCs offer the same practical control but with some surprising bells and whistles. Using the same FREE, streamlined PLC programming software as its predecessor, the CLICK PLUS PLCs provide no-headache programming combined with advanced capabilities like Wi-Fi communication and data logging. The Click and Click PLUS PLC series can be found at this URL: https://accautomation.ca/series/click-plc/ Features of the new Click PLUS PLC (C2-0xCPU) include the following: • Micro USB • DHCP support • DNS support • Wi-Fi (programming and Modbus TCP) • Bluetooth (Wi-Fi) provisioning • SD Card (Data Logging) • Data Logger • Network Time Service • MQTT (Publish/Subscribe) • Required PLC Password • Disable Ports • Strong Password Support • Disable Ping Response • Encrypted Password Transfer We are using the Click and Click PLUS PLCs for several reasons. Here are just a few. - Investment is low for the hardware, and the software is free - Standalone PLC with built-in I/O - Communication ability - Ethernet Port, RS232, RS485 - support for protocols such as Modbus RTU, Modbus TCP, etc. - Ability to directly expand the system with various modules, including RTD and Thermocouple inputs.
