ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
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
The C-more touch panels include a series of built-in System Setup Screens that allow you to view detailed information about the panel; adjust certain features; configure communications; test various functions of the touch panel; backup & restore firmware, a recipe, log, and project memory; clear memory and reset all values and conditions back to the … 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
We will now look at the C-More EA9 system hardware. This will include unboxing and powering up our C-More unit. Human-machine interfaces (HMI) are made to display and control operations for our automation solution. Information is displayed in a graphics format. (Graphical User Interface – GUI) The HMI is usually part of the SCADA (Supervisory … Read more
Secure PLC Email messaging is now available in the latest version of the Productivity Programming suite. SMTP or Transport layer security (TLS) email with an attachment and/or latest data log files can be sent. To be able to use this feature you must have installed Productivity programming suite v3.4 or higher and then load the … Read more
We will now look at communication between the Productivity 1000 PLC (Modbus TCP Server) and AdvancedHMI (Modbus TCP Client). Advanced HMI is a powerful, adaptable HMI/SCADA (Supervisory Control and Data Acquisition) development package that takes advantage of Visual Studio. There is no coding required and you can simply drag and drop items onto the page. … Read more
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
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
