Attached is an example consisting of LWE project and the associated LSC file.

The example shows you how to use the Web Editor to create a switch and a button.
The web server can only send a digital signal statically, like a switch.
When clicking the button, the web server sets the parameterized V-bit to 1 and then to 0 the next time it is clicked.
If you need a button, you have to solve it in the LOGO! program. With a LOW block you set a digital network output constantly to 0. The network output must have the same address as the associated network input.
In the example, it is VM-bit V0.1.
When the button is clicked, the web server sets bit V0.1 to 1. The LOGO! program reads with the network input (address V0.1) this signal with state 1. The LOW block then resets this VM-bit via the network output with the same address (V0.1).

Hello AutGen_7247452,

at first welcome to the forum.

Thanks a lot! Good job.

If you use the actually LWE V1.1.0 then you don't need this solution.
In the LWE V1.1.0 you can select if you want a push button or a switch.
