We will now look at the C-More Micro program quick start. This will demonstrate how to quickly get your C-More Micro Program up and communicating to your programmable logic controller. (PLC)
The general steps involved with a human-machine interface (HMI) program will include, program development, ladder logic, and HMI program development. We will be breaking the HMI program development into program purpose, tag import, HMI programming, simulation, and testing.
An EA3-T4CL C-More Micro HMI will be used to communicate to a Click PLC via Ethernet. A Start/Stop circuit will be programmed with a Timer. This can be controlled via the PLC inputs or HMI inputs. The timer present value (PV) will be shown on the HMI. The set value (SV) of the timer can be changed using the HMI. Let’s get started. Continue Reading!
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!
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 c-more 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 process temperature controller. 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!
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!
