The title this week is a common question asked by people of all ages that are curious. Sometimes just reading about something doesn't make it "click" in your mind. But actually seeing how something is done, turns on the light right away!
With this in mind, I posted some more HMI demo projects up on my website. These are projects from the manufacturer. By uploading and studying them, you can get some good ideas for your own HMI projects or learn how to use the great features built into EasyBuilder software.
There is even a game for downloading to the HMI. Try not to get caught playing during working hours!
Projects are here!
Please enjoy the holidays, and if you observe Christmas, Merry Christmas!

What's your favoite recipe?
Being near the holidays always brings up conversations about the great holiday food that someone made. Eating good food always ranks high on the things I like to do list. Although, I try not to over do it! Whenever I am eating a holiday meal someone always asks if they can get the recipe for whatever it is they are eating.
So, what does this have to do with HMI life?
Well, HMI's are commonly used to enter and manage setup parameters for controllers. When the parameters are lumped together as a block of information, it is referred to as a recipe. It is no wonder that recipe management is included in most HMI's.
Sometimes programming an HMI to do recipe management can be a little cryptic. In EB8000 this is referred to as "Data Transfer". The sticking points are setting up data blocks in retentive memory and then creating a way to designate which block of data to send.
So, I created a Recipe Demo project that demonstrates how to do this.
The Recipe Demo project demonstrates how to use a Data Transfer (Trigger-based) object to move consecutive words to and from a PLC.
1 of 5 blocks of words can be selected. It demonstrates how to use an Index word.
Internal HMI words are used for the demo PLC, but, in actual projects, PLC words are substituted.
Different ways to select the data block (recipe) are shown:
