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.
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.
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.
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.
The C-More HMI Panel can log data using the Line Trend Graph or PID Faceplate Trend Graph objects. When Save Log Data is selected on the Options tab configuration for that object, data is written to a “.txt ” file saved to the storage device selected.
Data Logging is commonly used to monitor systems and/or processes taking place at an industrial facility, providing time, date, and current conditions as configured on the Object. Data Logging can be used to collect temperatures, flows, alarms, levels, pressure and just about any instrument measurable condition.
We will be data logging from a Line Trend Graph. A register (word) made up of bits will also be logged. We will log this information every second on our USB stick. Starting/stopping the logging can be controlled on the HMI as well as USB reject. Once the USB is ejected, it can then be connected to our computer to review the files. We will also view and download the files from our web server that we enabled last time on our C-More EA9 HMI panel. Let’s get started.
We will now look at the C-More real-time clock object. 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 of the objects that are available to you.
The Clock Objects includes a couple of options to customize the display of a real-time clock (RTC) on a screen.
We will now look at the object list clock that we can use with our HMI panel. The clock objects that are available on the C-More EA9 are analog and digital. We will program each of these text objects. The source for the RTC clock will also be discussed and programmed both externally and internally. Let’s get started.
