Tank Filling and Emptying using Intouch Scada Script

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.

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.
