Controlling with external Python script

Hi @torayeff

OPC UA is a good option for this.
Many people also use TCP/IP and UDP communications.

There are many threads on the forum about this:

TCP/IP two way communication

Have anyone tried the two-way TCP/IP communication via python module? I modified the code published by Sicario https://forum.visualcomponents.com/forums/topic/tcp-ip-or-udp-communication-in-between-2-vc-instance-via-python-module/#post-6784 The one way send or receive mode works well. I used VC as server terminal and python script as the client. When VC received one data, it will send one feedback message to the VC server. However, I found the socket is not able to use anymore when the server …

TCP/IP socket connection with python

Hi, Here is an example of TCP/IP socket connection using python. We using non-blocking mode of socket connection which needs to be implemented via try-except method. All necessary codes and components attached here by. -Sicario   168_TCP_IP-Socket-Example.zip (1.26 MB)

Thank you for your time and I am looking forward to hearing your idea.
