Wiring an Inductive NPN PNP Sensor – Click PLC

We will now look at wiring an NPN and PNP inductive proximity sensor to the Click PLC. A proximity sensor (switch) is able to detect object presence without physical contact like a limit switch. No physical contact means that the switch has no parts that will wear out. The life span of the sensor is increased with less maintenance.
An inductive proximity sensor will detect ferrous metals. The sensor develops an electric field when metal (sensing object) is introduced usually killing the oscillation circuit of the sensor triggering the output.

We will be wiring an inductive proximity switch into the input of our Click PLC. The AM1-A0-4A is an extended range 12mm tubular sensor that can be wired into the PLC as a sink or source input. Let’s get started. Continue Reading!

C-More EA9 HMI Series Panel – PLC Settings

We will now look at the C-More panel settings for communication to the PLC. The C-More EA9 HMI (Human Machine Interface) Series Panel will communicate to the PLC directly through the tag database that we discovered in our first program. We were able to read and write individual bits in the PLC.
C-More EA9 HMI Series Panel to PLC and PLC to Panel Settings
Panel to PLC communications is used to write information into the PLC; like current screen number displayed, good communications, pop-up keyboard, and current language number used in the HMI.

PLC to Panel communications is used by the PLC to control the HMI. Switch to screen number, beep, increment and decrement the Clock by one hour, clear alarm history, clear alarm count, start screen saver and select language are the items you can control in the HMI.

PLC Error is used to communicate internally in the HMI the PLC error state and PLC error code value.
We will be setting up and testing our PLC to Panel and Panel to PLC communications on our EA9 C-More. Let’s get started. Continue Reading!

Wiring Push Buttons Switch to Click PLC

We will now look at wiring a click plc with selector switch and pushbuttons. A push button (pushbutton) is a simple human interface for controlling some aspect of a machine or process. The push button requires a force to push the button to change the electrical operation from off to on or vice versa. The condition of the output is usually momentarily. Some common everyday pushbuttons we use are keyboards keys.

A selector switch is also a mechanical device that will require a force to turn the electrical operation from off to on or vice versa. The selector switch usually locks into a position.
Wiring Push Buttons Switch to Click PLC
We will be wiring two illuminated pushbutton switches into our Click PLC. A selector switch will also be wired in. Let’s get started. Continue Reading!

Wiring Stack Light to a Click PLC

We will now wire a stack light to the Click PLC. Stack lights are usually modular stackable components that provide a visually illuminated and audible indication for machines, systems, and processes. They are usually located on top of equipment to provide this notification to personnel in the area.

Stack lights are also known as signal tower lights, indicator lights, warning lights, industrial signal lights, tower lights, and light towers.
We will be connecting a Patlite NPS-402-RYGB Super Slim stack light to our Click PLC.
Wiring Stack Light to Click PLC
These stack lights come in preassembled units in the most popular combinations of colours with ABS resin main bodies that offer superior impact and heat resistance; double-insulated construction enhances durability and safety. Interchangeable light modules require no rewiring. Let’s get started. Continue Reading!

C-More First Program – EA9 Series Panel HMI

We will now put our first program into the C-More EA9 HMI Panel using the C-More programming software. The Do-More Designer Simulator will be used with a modified Start Stop Jog Circuit so we can use our C-More HMI screen to monitor the output as well as control the inputs on the PLC.
C-More First Program - EA9 HMI Series Panel
Communications will be established to our C-More EA9-T10CL unit and the firmware will be updated. We will then develop our control for our PLC ladder logic circuit.
C-More First Program - EA9 HMI Series Panel
The PLC logic for our circuit can be found on our post: How to Make a Start / Stop / Jog Circuit in a PLC. The YouTube video can be seen here.
Our C-More EA9 HMI Panel will be communicating to the PLC simulator via Ethernet with the Modbus TCP protocol. Let’s get started. Continue Reading!
