Learn how to create logic using Wonderware InTouch SCADA software using the scripting language.
InTouch Scada Scripting
There are six types of logic gates. We can create a voting system using them and also, we can create PLC programming logic using a combination of them.
Here I will create a script to turn ON lamp by using all logic gates. To do that so, open InTouch application.
Step 1:
Create a new project and enter an animation environment as shown in the below window.
Step 2:
Go to the wizard as shown in the below window. And add a switch and lights. As we are using six logic gates we will add twelve switches and six lamps.
Step 3:
Add all the objects as shown in the below window. Give tag name as per text. Do read my article on it.
Step 4:
Right-click on the display as shown in the below window. Select “windows script”.
Step 5:
The following scripting window will open. Select condition type. In “on a show” it will always remain starting condition.
In “while showing” option, we have to write a script to operate switch and lamp. Also, select every and enter some time in it.
Step 6:
Here, I have added an initial condition as shown below. It always remains zero.
Step 7:
In “while showing” I have written condition to turn OFF and ON gate, based on the type of logic gate and lamp will turn ON accordingly.
Step 8:
After writing down condition click on “validate” than “convert” and then hit “ok”.
To test the logic click on “runtime” located on the top right of the below.
Step 9:
When switches are OFF NAND, NOR AND XNOR gates will remain ON.
Step 10:
When S1 is ON then OR, NAND, and XOR gate’s lamp will turn ON.
Step 11:
When S2 is ON then OR, NAND, and XOR gate’s lamp will turn ON.
Step 12:
When both S1 and S2 are ON then the lamp of AND, OR and XNOR will turn ON.
