HMI System

With the HMI System application it is possible to create a visual interface between the user and the PLC in a very easy way, only by making drag and drop the desired control, a powerful HMI system can be created in few minutes

The communication between the console and the PLC can be bidirectional. For example it is possible to show messages, images, values of the data blocks, to introduce numeric values by means of text boxes, command buttons or by using a function bar, all these features are communicated with the plc program.

Each program of PLC can have a different console associated, also during the program execution it is possible to load different consoles. If this function is enabled, at the beginning of the PLC the console will appear and it will show the different programmed functions.

The EasyPLC HMI editor has advanced controls for the data representation elaborated by the PLC program or acquired by the I/O cards, for example:

Graphic Bars: to show the data stack value in a graphic bar, you can program the visualization scale, as well as some alarms, if they are overcome automatically it changes the colour programmed by the user to the red colour.

Data Charts: the data can be visualized in different types of charts (bars, lines, points, 3D, etc), for a better understanding of the processed data.

REMOTE PANELS VIEWERS

In certain applications it may be necessary to use an alternative display system, for example if you don't want to use your PC monitor to perform the function of HMI or other causes. The software allows two display systems that can connect to the PC USB port and can be managed directly by EasyPLC, in order to show messages, graphic information, exchange data between the PLC and the users or many other functions. These systems can be mounted directly by the users following the diagrams, with the advantage of being low cost, as used commercial standard items are available at any electronics store, or can be easily found at online resellers.

HMI System

The PLC Systems must have tools to provide a graphical interface to exchange information between the users and the computer. The HMI, Human Machine Interface, that EasyPLC provides is the application called HMI System
