C-More EA9 HMI Series Panel Installing the Software

The C-more Programming Software is a free download from Automation Direct. The software can run in DEMO (demonstration) mode or a key can be purchased to unlock this software. 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 the screen construction area. A complete set of control panel objects include pushbuttons, selector switches, pilot lights, text and numeric data displays, bar graph displays, static and dynamic bitmapped images and more. Configure your PLC tags and click on the objects you want to use. A built-in simulator will allow you to review your work on the computer before downloading the project.

We will be installing the C-more Programming Software onto our PC (computer). This will be the DEMO mode of the program. The DEMO mode will do the following:
– You CAN download our sample projects and explore the capabilities of C-more.
– You CAN use the Simulator to test your project on the PC and see how the Simulator can save you hours of programming time.
– You CAN create your own objects, and save them in your object library.
– You CAN explore the online help, and find answers to many questions that might not be covered here on the website.
The full package will allow you to save your projects, download them to a panel and includes the full symbol factory library with over 4000 symbols.
Let’s get started. Continue Reading!

C-More EA9 HMI Series Panel System Hardware

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 Control and Data Acquisition) system.
Communication from the HMI to the control is usually done through a serial (RS232 / RS485 / RS422) or Ethernet (RJ45) method with different protocols depending on the manufacturer of the control. The automation control device is not limited to a PLC. (Programmable Logic Controller) You can communicate also to drives, temperature process controllers, etc. The HMI usually will include several different protocols and port configurations to maximize the amount of control product that it will be able to communicate.

C-More Operator Panels come in 6”, 7” wide, 10”, 10” wide, 12” or 15” models. They are programmed using the EA9-PGMSW programming software through either the USB or Ethernet cable. A voltage supply of 12-24 VDC is required for the panel. The optional C-More AC Power Adapter EA-AC can also be used to supply this voltage.
We will be looking at one of the newest members of the C-More Panel HMI devices from Automation Direct. This is the EA9-T10CL. This ten-inch colour TFT LCD screen offers great features that we will be exploring as we review this product. Let’s get started. Continue Reading!

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 different high speed counter modes available in the click. (External Interrupt, Pulse Catch, Filter) This is all setup through a user friendly graphical user interface. We will also combine the Frequency Measurement and the High Speed Count in one application. Let’s get started! Keep on Reading!

Click PLC High Speed Counting – Part 1

The Click PLC family has been updated, and now has the ability to use high speed counting. This is available on all of the Ethernet units that have DC inputs. The faster processor on the Ethernet unit (3 to 10 times faster than the basic unit) allows this capability. There are seven (7) different modes of operation for the high speed counter available so adaption to your automation solution is easy. The input can count Up, Down, Up/Down, Pulse/Direction or Quadrature (with Z). Maximum speed on the high speed counter inputs are 100 kHz. That is 100,000 pulses per second.

We will be looking at the different high speed counter modes available in the click. This is all setup through a user friendly graphical user interface. Let’s get started! Keep on Reading!

Click PLC HMI Rotary Encoder Dial Input

Rotary encoders are modern digital devices that have taken over from the potentiometer in stereos and many other applications. This is because of their fine digital control and they can fully rotate without end stops. We can connect the rotary encoder into the PLC using just two digital inputs. This human machine interface (HMI) has the advantage over touch screens and other methods of control into the PLC. The operator can control the rate and set point with the dial (rotary encoder) without looking at the control. This will allow the operator to concentration on other tasks.


We will be connecting a rotary encoder with dial into the Click PLC. The signals being sent from the rotary encoder will be explained. Different methods of programming this input in our PLC will be discussed. Let’s get started. Keep on Reading!

Click PLC Update Firmware

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 the low level interface between the hardware and software. The Click PLC firmware comes with the programming software.

We will be updating our firmware of our Click PLC from 2.10 to 2.30. Let’s get started! Keep on Reading!

C-More Micro HMI Object Text

The C-More Micro HMI Panel software uses virtual components called Objects. Five different text objects are available for your industrial human machine interface. (HMI) Static text will place words on your HMI page. Lookup text will display a message corresponding to a value in a tag register. Dynamic text will display the ASCII (American Standard Code for Information Interchange) equivalent of the information in the tag register specified. Scroll text will display information too large to display in the area assigned. This will move the information in the display area so the entire message can be seen. Text entry will allow the user through a pop up key pad to enter ASCII characters into a tag register.

We will now look at all five of these text objects our HMI micro panel. A new page will be made to show all of the text object functions and operations. Let’s get started. Continue Reading!

C-More Micro HMI Object Recipe

The C-More Micro HMI Panel software uses virtual components called Objects. Recipe buttons are part of these objects. The Recipe Button Object changes the value of a tag or multiple tags. The Recipe Button Object looks and acts like a Pushbutton Object on the screen. When the Recipe Button Object is pressed, the values in the Source Data Tags are written to Destination Data Tags.

We will now look at recipes that we can use with our HMI micro panel. They include the recipe button. We will program 3 recipes into the unit that will control 4 different timers. Let’s get started. Continue Reading!

C-More Micro HMI Object Bitmap

The C-More Micro HMI Panel software uses virtual components called Objects. Bitmaps are part of these objects. These bitmaps are images that are made up of tiny dots called pixels. Each of these dots are actually a small square that contains one colour. Bitmaps will help you produce simple, intuitive looking human machine interfaces.

We will now look at bitmaps that we can use with our HMI micro panel. They include bitmap buttons, static bitmap, dynamic bitmaps and multi-state bitmaps. Let’s get started. Continue Reading!

C-More Micro HMI Object Meters and Graphs

The C-More Micro HMI Panel software uses virtual components called Objects. Meters and Graphs are part of these objects. They can represent a range of numbers and are programmable to simulate the functions that you require on your automation project. This helps you produce simple, intuitive looking human machine interfaces.

We will now look at the meters and graphs that we can use with our HMI micro panel. They can replace the older chart recorder equipment that is still in use in some manufacturing facilities. These objects will represent the data in the PLC for the user to interpret. Let’s get started. Continue Reading!
