The main purpose of SCADA in industries are,
1. For Data Acquisition
2. Graphical Control.
3. Easy to interpret with data while being controlling field instruments from the SCADA.
There may be times when we have to store the data in the spreadsheet for later use or visualizing them instantly.
So now we are going to implement how we can communicate Excel from InTouch SCADA.

Data Communicate with Excel from InTouch
HMI 2023
First of all, I am going to pull out a slider & tank from industrial
graphics Library to make it graphically inclined.
2.
3. I will choose the tag as I/O real. Which means this tag can act as input
to this project or output from the project to another software.
4. After choosing I/O real we are going to give access name, click on
ADD to add an access name. We have given “Communication”, this will
be used for specifically this project,
You can give any name to the Access text box. Notice that the node
name has to be empty. The application name is excel since we are
going to communicate with it.
Select “DDE” in which protocol to use,
The topic name should be the name of the excel file and the format of
all excel files are .xlsx. Notice that we are going to use the DDE
protocol to establish communication.
5. After adding the access name there will be a text box called “item”, we
have specified in there which column and row the value has to be
stored in the excel sheet. We put “R1C1” Then save the tag and exit.
Now our created tag is ready to act as I/O tag.
So before going to the run time you have to open the Excel and create
a new file with the same topic name with proper extensions as given in
the Add access name (we created as “Tank_Level.xlsx”) dialog box
leaving out the format and save the file anywhere on same system.
Now we are going to give Break cell to the tank and access the
percent fill of the tank. I am going to give the same tag name here so
whenever there is movement on the slider it’ll reflect on the fill percent
of the tank.
6. Now we are going to runtime (upper right corner), before going to the
runtime remember that the excel file which we saved is open already.
7. Notice that the value is accurately getting printed in the excel sheet
since it was a real tag.
Another side, you can check, if we enter 50 in R1C1 cell and hit enter,
changes will be done on slider & tank level as well,
If we enter 75 then it works same and shows result accordingly.
