The C-More EA9 Series of human-machine interfaces (HMI) provides a way for the operator to control and will perform a lot of additional items. The free programming software is very user friendly and fully featured. Here are some of the additional items that this robust and powerful HMI can do besides communicating to programmable logic controllers (PLCs).
Send Email – This includes authentication for the email client protocol
Log Data – This can log data files to the internal memory or an external thumb drive (32G)
FTP Server – Use file transfer protocol to retrieve information from the HMI to a network. This can be done automatically with a batch file.
Web Server – This HMI can be a web server on your network
Remote Internet Access – Windows, Android, and IOS operating systems have the ability to take advantage of this remote access to the HMI. The programs are free and fully functional.
Our sample CP1H PLC program will use buttons and indicators to control a start/stop jog circuit. An analog input into the PLC will be scaled and displayed on a gauge and numeric display on our HMI screen. We will also write information to our 7 segment display on the CPU from our HMI screen. Omron serial host link protocol will be used to communicate over an RS485 serial cable. We will demonstrate remote access using our windows and android device. Let’s get started. Continue Reading!
Operators in your Arduino sketches (programs) consist of comparison blocks, concatenate strings, bitwise operators, string conversion, ‘not’ operator, and compound operators. These operations generally will be used with other instructions in your sketch. It is important to understand what instructions are available and what they are designed to accomplish.
We will be looking at each of these instructions that are available using productivity blocks. A sample sketch will be shown that will use some of these operators. The sketch will get a number between 1 and 100 from the built-in Arduino IDE (integrated development environment) serial monitor. It will print the number on the monitor if it is between 1 and 100, else it will print try again. Let’s get started! Continue Reading!
The cmore EA9 HMI has an event manager that can be used to trigger actions based on various events.
We will be adding a Click PLC to our headless RHMI cmore EA9 program that we created last time to communicate to the solo process temperature controller. The Solo will be connected via RS485 using the Modbus RTU protocol. Using the Modbus TCP protocol we will connect the Click PLC to the Ethernet port. Using the event manager we will be writing the set value (SV) and present value (PV) of the solo process temperature controller to the Click PLC. We will also allow the Click PLC to write the SV into the solo. This is in addition to the writing of the set value via remote apps and the solo itself. Let’s get started. Continue Reading!
The cmore EA9 HMI can connect to the Solo process temperature controller using the built-in RS485 serial communication port. This will connect up to 32 solo units back to the HMI for display and control.
We will be setting up our headless RHMI cmore EA9 to communicate to the Solo process temperature controller. Using the information that we have discussed previously, we will set up data logging, file transfer protocol (FTP), bitmaps, etc.
We will also set up an object library of the Solo 4896. This will consist of a bitmap, numeric display, numeric edit, indication lights and up and down increment. The system will then be controlled using the remote applications discussed last time. Let’s get started. Continue Reading!
Remote access will allow for viewing or controlling the C-More EA9 HMI series. We can use any windows based machine or use the C-More remote HMI App from Apple iTunes store, Google Play or Amazon App Store for mobile devices. This software is available free of charge.
Setting up the EA9 series for remote access and control is done through the C-More programming software to the HMI. We will be downloading the Windows application from the c-more panel. This is done through the web browser of your computer. We will also look at the c-more remote HMI app from Google play. Let’s get started. Continue Reading!
The C-more headless EA9-RHMI is programmed using the C-more Programming Software, EA9-PGMSW. The developed project is transferred from the PC to the HMI by either a USB or an Ethernet connection between the two. Previously we used the Ethernet connection to establish communication.
We will be using the USB connection to establish communication, save the program and review the setup screens of the Headless C-more.
Troubleshooting of the USB connection and windows driver will also be discussed. Let’s get started. Continue Reading!
The C-More EA9 HMI Panel now comes in a headless version. (EA9-RHMI) All of the great features that are already built into the EA9 are available with the new headless model. This unit can be mounted within the cabinet and you can decide how to display the information.
This user-friendly, time-saving software platform allows your system data to now be shown to the operators in new ways thanks to the C-More headless HMI panel. Capabilities like data logging, FTP (File Transfer Protocol), secure email, remote HMI and data sharing can now be added to existing PLC hardware.
We will be unboxing this EA9-RHMI unit. Once power is supplied to the unit we will then establish communication and save the program. Let’s get started. Continue Reading!
The C-More EA9 HMI Panel through the Ethernet port can send secure email messages. These mail messages with attachments can be sent through a specified mail server.
We will be sending an email using a Gmail account with authentication. This will also include an attached logged data file. We will also discuss how the C-More HMI can send a text (SMS) message. Let’s get started. Continue Reading!
The C-More EA9 HMI Panel through the Ethernet port can be set up to use FTP (File Transfer Protocol). FTP is a standard network protocol used to transfer computer files between a client and a server on a computer network.
The C-More HMI can be used as an FTP Client or Server depending on your application.
An FTP client can send and receive files from an FTP server site. You will need an FTP Server already set up in your network to use this feature. (Example: FTP Web Server) See the help file in the C-More software for more information on the Cmore FTP Client Setup and use.
The Cmore FTP Server can retrieve data from the C-more memory with requests from the client. The power of this setup is the ability to automate the retrieval of the information using a batch (BAT) file. We will be setting up the FTP Server function and access the data log that we set up previously using a PC as the client. Let’s get started. Continue Reading!

It is a good time to be in the automation business. Technologies are merging and communicating like never before. What was impossible is now possible for the industrial plant floor. We are looking forward to the New Year and new possibilities for implementing your control solution.
Each year we like to take a few minutes and reflect on the past, current, and future of ACC Automation. You have helped us to build the site that you see today through questions, comments, and suggestions. Thank you.
2019 has been our best year yet thanks to you. Keep on Reading!
