ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
We will now look at the C-More EA9 object shapes. These shapes can move and resize when connected to the PLC. The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few … Read more
Safety controllers monitor over-voltage / short circuit protection, redundant relays, and positive guided contacts to provide a level of fail-safe operation for applications. The modular MOSAIC safety controller is an expandable, cost-effective choice over standalone safety relays. Especially as the required number of relays/channels increases. It will also reduce the wiring of your safety circuits. … Read more
We will now look at the C-More simulate project mode on the C-More EA9 Software. The C-More HMI Panel programming software has a simulation mode. This simulator will allow you to test your project before transferring it to a panel. Testing your application is a vital step in HMI program development. This feature of the … Read more
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
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
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
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 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
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
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
