When the BOOL variable (variable 1 and variable 2) is connected to the touch screen, when variable 1 is 1, it actively switches from screen 1 to screen 2, and when variable 2 is 1, it actively switches from screen 2 back to screen 1, can it be realized on the touch screen?
You can switch screens by changing the variables.
1.ProTool: Create a new variable 1, in the feature of variable 1 - function, select "Event" as "Numerical Change", select the function as "Change the animation surface fix", and select the parameter "Screen 2"; Variable 1 features - Options, select "Continuous Read". The same is true for configuring variable 2.
2.WinCCflexible: Create a new variable 1, in the event of variable 1, select "Change Value", select the function as "Activate Screen", and select "Screen 2" for the parameters; Variable 1 convention – collection pattern picks "loop continuous". The same is true for configuring variable 2.
The principle of this is that when variable 1 is changed (whether from 1 to 0 or from 0 to 1), it will switch to screen 2, regardless of what the picture is at that time.
In WinCCflexible, I usually do this, only define one variable 1, select "change value" for the event, select the function as "activate screen number", and the parameter is still select variable 1; Note that each screen has its own screen number in its features; Variable 1 convention – collection pattern picks "loop continuous". Variable 1 is able to use variables from the PLC.
The principle of this is that at the beginning of the project, variable 1 is set to 1, and the number 1 screen is displayed, and when variable 1 becomes 2, the number 2 screen is displayed, and so on...
