wincc OA 3.20 version

[admin_01]

Hi everyone,

I need to interact with OPC data—both reading from and writing to OPC UA servers. Could you explain in detail how to configure and implement this

I'm currently working on a project in WinCC OA version 3.20, and I need help with few things: 1. I want to write a control logic e.g., if a value exceeds a trigger an alarm or set another tag).

I need to bind a data point (tag)to a text field or slider in a panel. What's the recommended way to do this in version 3.20

Information how to use the OPC UA client in WinCC OA you can find in the WinCC OA Documentation:

For triggering alerts in WinCC OA you can use the _alert_hdl config. How to configure an _alert_hdl config is described in the WinCC OA Documentation:

Interaction between data and the user interface is possible with objects and scripts in CONTROL (WinCC OA programming language).
