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.



The remote panel USB 128x64 GLCD Nirtec is based on Microchip PIC18F4550 micro controller. The assembly does not need external power because all components receive the necessary voltage from the USB port where the card is connected. The graphic LCD display used is a matrix of 128 by 64 pixels and is compatible with any models that contains graphics controller KS0108 or S6B0107 or S6B0108 all from Samsung. Pay special attention to the connections of the display with the micro controller, depending on the model it may have different wiring. The potentiometer connected to pin No. 3 has the function of adjusting the screen contrast.
