Using Properties as Text Variables in Twincat 3

Question

I am trying to make a project, where I control variables read and write from the HMI/visualization through properties of function blocks. I am new to Twincat and OOP,and I am lost as to why I can pass a property as text variable to an element in visualization. The error I am getting is:

I am doing it this way so that I can monitor when a change happens to the variables, such as a worker changing a value or smth. Any idea on how this can fixed? Is this the case for HMI as well, or is it limited to visualizations? THank you in advance.

Answer 1

It looks like you are using Twincat PLC HMI or a .Net project. The twincat-hmi tag is for Twincat HMI HTML based visulisation TF2200.
