Create Buttons in HMI and Activate Outputs in a PLC Fatek
The HMI Touchscreen is the representation of a control system mainly the programmation developed in a PLC; So if we have a HMI we have a PLC, here we gonna see the first steps to develop complex SCADA; in a HMI you can see Data, Inputs, Outputs, Sensor, etc
First we must to review these concepts:
- Flags (M): Very important to this level work with Flags "M" these are Electrical-Software contacts very useful to create infinite control logic; FLAGS are so important to create BUTTONS in HMI
Create our program with the buttons Start and Stop
If you haven't downloaded HMI Software you can download free Download HERE Easybuilder Pro and remember you can download free the Software Winproladder Fatek Download in Fatek Webpage HERE
Let's create a simple project "Start M0 - Stop M1" with 2 button in HMI; and activate a "Output Y0", of course always consider real buttons (X0 - X1)
Now let's create the Buttons in HMI, these buttons will start and stop the Y0 Output, we choose the option "Toggle Switch"
For better create 2 differents buttons, One is just for START (M0) and other just for STOP (M1); remember these values were configurated in Winproladder, the buttons will have the typical color for START (green) and STOP (red)
Create a BIT LAMP to Monitoring when DIGITAL OUTPUT "Y0" IS ACTIVATED, assign Y0 from PLC Fatek to the Bit; in this case is the real Output monitoring from HMI Weintek
The program we have configurated is simple but is important understand what we have done!
Finally communicate PC and PLC and DONE! We are ready to use the buttons configurated by tag "M" to START or STOP to activate the real Output "Y" ´from PLC Fatek
Remember if you haven't programming a PLC Fatek before, go to Programming PLC Fatek since 0 HERE
