TwinCAT 3 HMI button as a counter
问题
我想在TwinCAT 3 HMI中使用按钮作为计数器。例如，工作流程如下。我有10个函数，我必须通过按下一个按钮来逐个触发这些函数以在TwinCAT 3中触发它们。我该如何做到这一点？
英文:
I want to use a button as a counter in TwinCAT 3 HMI. For example, the work flow is like this way. I have 10 functions and I have to trigger one by one by pressing a single button to trigger the functions in TwinCAT 3.
How can I do this?

首先，您需要将按钮链接到一个函数（例如，将其链接到按钮的'OnMouseClick'事件）。
链接的函数充当主函数，根据内部计数器值调用正确的函数。
因此，基本上，您需要以这样的方式设计主函数，使其
- 每次调用时增加一个计数器，并且
- 根据实际计数器值调用正确的函数。
英文:
First, you need to link the button to a function (e.g. by linking it to the 'OnMouseClick' event of the button).
The linked function acts as a master function which calls the correct function depending on an internal counter value.
So basically, you design that master function in a way, that it
- increments a counter every time it is called and
- calls the correct function depending on the actual counter value.
