This article is about how to write a script for tank filling and emptying using a script in InTouch SCADA software.
Tank Filling and Emptying
Follow the below step to see the script to fill and empty the level of the tank.
Step 1:
Open InTouch SCADA.
Create a new project and enter an animation environment.
To add a tank, click on “wizard” then click on “symbol factory” and hit “ok” to proceed.
Step 2:
Search tank and add a tank that you want to use.
Step 3:
After adding a tank to the screen, add one switch to provide the condition to fill the tank.
Step 4:
Double click on tank to add properties and to give a tag name.
Click on “animation” and then choose “vertical”.
Step 5:
Clicking on a vertical will open up a new pop-up window as shown in the below window.
Step 6:
Give a tag name and choose the range you want to add. Hit “ok” to proceed.
Step 7:
New pop-up as shown in the below window will open up.
In type choose memory integer. Choose maximum and minimum value. Hit “save” then close the pop-up.
Step 8:
Give a tag name to switch too. Hit ok ton proceed.
Step 9:
Now I will write the script. As I am using a single-window script I will use windows script.
Do a right-click and choose windows script.
Step 10:
Here I have added a script to fill and empty the tank with the help of the switch.
In the first line of a script, you can see that to fill the tank I have used condition (==) and result (=).
Condition: If my switch is “1” means ON and tank level is less than 100 then the tank is going to fill (T = T + 2) with a rate of “2”. If you want to fill the tank in less time you can use any number from 1 (Low) to 10 (High).
In the tank emptying process, I simply have used OFF switch means when I put off the switch and level of the tank is greater than 0 (zero) then the tank is going to empty (T = T – 2).
So, “+” to fill the tank and “-“ to empty the tank is used.
Click on “validate” than “convert” and “ok” to load the script.
Step 11:
Check the process by clicking on the “runtime” button.
