4.5.2 Submenu - Logic 1-4

A new submenu opens for each activated logic. The following settings are possible:
ETS Text
Logic object A/B
(external)
Internal input 1/2
Taste 1-2/4/6/8
Button selection
Table 42: Settings – Submenu: Logic 1-4
Up to two external logic objects can be activated for the logic operations "AND"/"OR". The default setting
defines the value of the external logic object after a bus power return if no value has yet been sent to the
communication object. Up to two buttons can be defined as "internal inputs" and the respective value that
the button sends when pressed.
Note: The setting "Send value on button activation" is a special function. This can be used to send a
second value when a button is pressed - in addition to the normal switch function. The value is determined
under "Setting logic X" (previous chapter). Here, the button that is to send the value is selected via the
"Button selection" parameter.
Depending on the activated inputs, the following communication objects are available:
Number Name / Object function
* 20/40/60/80 Logic 1 – Input A
* 21/41/61/81 Logic 1 – Input B
Table 43: Communication objects – Logic inputs
* Object numbers depend on the device version (number of buttons).
