Value direct writing
The customer must press a function key, a tactile zone or a tactile key of a XBT terminal, to write a PLC variable or a constant in another PLC variable.

R3 10 mn

R7 R8

But the customer can also directly operate on PLC or terminal variables.
For example, in the case of the PLC, increase/decrease a variable with a fixed step.
For example, in the case of the terminal :
- change the application language :
- Action : Writing value
- Variable : XBT:5062-language
- Value : Constant=0,1,2 (1,2,or 3rd programmed language)
- Label : bitmap
- directly control the screen brightness (control of the function night/ dayfor example),
- Action : Writing value
- Variable : XBT:5063-brightness
- Valeur : Constant=0 to 100 (% of brightness)
- Label : bitmap
- directly call a system page. (
see "Displaying a system page by writing a public variable", Page 29 ).
