Wiring an NPN PNP 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. A capacitive proximity sensor will detect ferrous and non-ferrous objects. The sensor works … Read more

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 … Read more

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. Panel to PLC … Read more

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. Communications will … Read more

Productivity 1000 Series PLC PID Ramp Soak

Productivity PLC – PID Ramp Soak Instruction The purpose of a ramp soak instruction is to make gradual, controlled changes in temperature (Ramp), followed by a temperature hold (Soak) period. We will be using our Proportional-Integral-Derivative PID Instruction that we looked at last time to apply the ramp/soak instruction. Using the immersion heater in a … Read more

Productivity 1000 Series PLC PID Instruction

PID Loop (PID) Instruction (Auto Tuning) – Productivity 1000 PLC A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the Error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the … Read more

C-More EA9 HMI Series Installing the Software

The C-more Programming Software is a free download from Automation Direct. This fully-functional version of the C-More EA9 Programming Software is now available free of charge. This powerful C-more Touch Panel programming software makes HMI touch screen panel setup and programming quick and simple. Simply drag and drop the objects from the object bar onto … Read more

Productivity 1000 Series PLC Firmware Update

Firmware is usually PLC operating system code that is written into a read-only memory. The BIOS (Basic Input Output System) of a PC (personal computer) is a good example of firmware. It provides a low-level interface between the hardware and software. The firmware for the productivity series of PLCs must be downloaded separately from the … Read more

Click PLC High Speed Counting – Part 2

The Ethernet Click PLC high-speed counter has seven different modes of operation. In Part 1 we discussed the High Speed Count Mode, Interval Measurement Mode, Duration Measurement Mode and Frequency Measurement Mode. This 100 kHz counter can accept Up, Down, Up/Down, Pulse/Direction, or Quadrature (with Z) inputs. We will be looking at the last three … Read more
