11.5.12 Application - 2-button switching
The application makes it possible to switch a light via a button pair.
The following communication object is available:
"Sx: switching"
■
At the press of one of the two buttons a switching command is sent via the same
communication object. The application distinguishes whether the first or second button is
pressed.
The application makes a joint set of parameters and communication objects available in function
block x for both buttons.
Note
The parameters for application "2-button switching" can be called up via general
parameters.
Note
The number (S1 - Sx) of the object depends on the function block and the button
number.
11.5.12.1
Working mode of the buttons for switching
Options:
1st Button on / 2nd button off:
■
–
When the first button is pressed the "On" command is sent and the "Off" command
when the second button is pressed.
1st Button off / 2nd button on:
■
–
When the first button is pressed the "Off" command is sent and the "On" command
when the second button is pressed.
Alternating on/off:
■
–
"On" and "Off" are sent alternately at the press of the first or second button.
The parameter is used to specify, for example, whether a light is switched on or off with the first
and second button.
A further option can be specified as to whether the switching commands are sent alternately,
independent from the button pressed. This means that after "On" is sent, "Off" is sent at a
renewed press of one the two buttons. After one of the two buttons is pressed again, "On" is
sent again.
This also applies for values that are received via the associated 1-bit communication object "Sx:
switching". This means that when an Off command is received after an On command was sent
via object "Sx: switching", an On command is sent after the button is pressed again. It must be
ensured here that the S-flag (writing) of the communication object is activated.
