C-More EA9 HMI Series Panel to PLC and PLC to Panel Settings

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 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!

C-More EA9 HMI Series Panel First Program

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 HMI screen to monitor the output as well as control the inputs on the PLC.

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.

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!

C-More EA9 HMI Series Panel System Setup Screens

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 original factory defaults.

Information, Setting, Test Menu and Memory make up the four Main Menu setup screens.
Information – The information tabs display details about the touch panel model; the panel’s name; version information for the hardware, boot loader, and firmware; clock source, and beeper status. Other tabs display details on the panel’s internal memory and the status of any external memory devices. Communication port details are available in this area, as well as an error log to help in troubleshooting the system.
Setting – This is the area for making adjustments to the internal clock, adjusting the brightness of the display, setting the IP address adjusting (calibrating) the touch panel, enabling or disabling the internal beep, and enabling or disabling a mouse pointer.
Test Menu – This menu will allow you to test the touch panel, test the display, test the user LED, test the communication ports, and test both the internal beeper or the audio line output. If a speaker with an amplifier is connected, a WAV sound file is a system provided for the audio line output test.
Memory – The Memory menu allows you to either backup or restores your project, log data, recipe data and/or system memory. Selections can be made to backup to optional SD card memory or USB pen drive memory. The menu selections also give you the ability to clear the memory, and there is also a selection to reset all of the touch panel settings back to the original factory defaults.
We will be reviewing these system screens of the C-More HMI Panel. 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!

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!

Create a PLC with HMI Training and Learning Environment Free

Learn PLC programming and use a powerful HMI (Human Machine Interface) easily and free. We will use the Automation Direct Do-More programming software tied into the Advanced HMI package via Modbus TCP.
PLC HMI Training Learning 0080-min

Our application will show a HMI screen with a panel meter and a reset button. The panel meter value may be changed by clicking it. This will bring up a input screen to put in a number. When the reset button is selected the input value entered will show on the panel meter.
PLC HMI Training Learning 0310-min

Since we will be communicating via Modbus TCP, the following table shows the Coil/Register Numbers and the associated Do-More PLC Addresses.

Coil/Register Numbers Data Addresses Type Do-More PLC Table Name
00001-09999 0000 to 270E Read-Write MC1 to MC1023 Discrete Output Coils
10001-19999 0000 to 270E Read-Only MI1 to MI1023 Discrete Input Contacts
30001-39999 0000 to 270E Read-Only MIR1 to MIR2047 Analog Input Registers
40001-49999 0000 to 270E Read-Write MHR1 to MHR2047 Analog Output Holding Registers

Note: The Do More PLC uses the Modbus area to communicate. This is because having direct access to the digital I/O can be dangerous when connected via Ethernet to the internet. Data must move in and out of this area via the PLC program.

We will first start with the PLC.
Automation Direct has a powerful simulator with their Do-More PLC. It is the Do-More Designer Software. This software simulator includes the entire instruction set (Not Just Bit Logic) as well as communication protocols. It can be downloaded and installed for free from the above link.
Our PLC program will have the following addresses:
Digital Panel Meter Present Value (PV) – MHR1 – Modbus 40001
Digital Panel Meter Set Value (SV) – MHR2 – Modbus 40002
Reset Button – MC1 – Modbus 00001

The first rung of the ladder will use the 1 second pulse bit and increment the PV value of our digital panel meter. This will also compare the current value to 4000 and if greater or equal, move the value of zero into the PV value.

The second rung of the ladder will move WX0 analog value from our simulator into the PV value of our digital panel meter.

The last rung of ladder will move the SV value into the PV value of our Digital Panel Meter. This happens when the reset is hit.
