Quick video tutorial: Using Python with TK Data Access, Using Python with Script Task, Using Python with Code Behind (no audio)

Overview

The programming in many of your projects will consist of C# or VB.Net 100% managed code that is designed to run in the Microsoft .NET framework.

...

Warning

All of the methods listed above are disabled for Mono projects and HTML5 displays.


...

TKDataAccess.py

Must use for Python developers, you You can create code in the Python environment and use the TKDataAccess.py file to interact with the projects. 

Warning

Tatsoft provides the TKDataAccess.py is provided by Tatsoft, and when usedfile. When you use it, you need to make sure the installPath into the TKDataAccess.py file is with the correct path of Studio installation.it is installed in the same folder as FactoryStudio. 


Below are some methods from TKDataAccess.py that you can use:

...

Code Block
GetConnectionStatus ()                 

           

  • Check whether is connected to your script's connection to the server
Code Block
IsConnected ()

...

The Python code using the TKDataAccess.py module in Main.py is described below:

Code Block
import sys
from Extensions.TKDataAccess import TKDataAccess dataAccess = TKDataAccess()
connectionStatus = dataAccess.Connect("127.0.0.1:3101", "guest", "") print("Connection: " + connectionStatus)

if dataAccess.IsConnected() :
ret  =  dataAccess.GetObjectValue("Tag.tag1") print("Value: " + str(ret)) dataAccess.SetObjectValue("Tag.tag2",  ret)

dataAccess.Disconnect()


Then, you need to create a the code that is shown below or create a Python Script Task that executes the Main.py file, which contains the calling for TKDataAccess shown above. So here, we will use the Python namespace as previously described.
