Chapter 4: Binary inputs
4.2
Binary inputs, 4-gang
Binary input REG-K/4x24
Multi-function.counter 12BA/1.0
Art. no. 644892
You can use the counter reset function to reset the im-
pulse counter and the cycle time or the switching
counter of another input. Additionally, you can use this
function to transmit switching commands.
You can determine whether the count should be reset
while the pulse edge is rising or falling, or while it is
both rising and falling.
Additionally, you can program a switching telegram to
be transmitted when the pulse edge is rising and/or fal-
ling.
Communication objects
You can select the following communication objects:
You can use the cyclical monitoring function to trans-
mit telegrams cyclically. This is necessary when other
devices are monitoring the presence of the push-but-
ton interface via their cyclical telegrams (protection
against theft, fault monitoring). If no telegram is recei-
ved from the push-button interface within a paramete-
risable time period, e. g. a signal is issued by this
device. For this purpose, you can parameterise the
push-button interface accordingly.

When a disable function is activated via the
disable object, all current push-button functions
are reset or interrupted.
Communication objects
You can select the following communication objects:
You can block the inputs in two different ways:
1. Separately for each input
2. All inputs function as a master input
You can determine whether a disable object = 0 or = 1
should be blocked.
Separately for each input
You can use this function to block each of the four or
eight inputs individually. When an input is blocked, it
fulfils no function. You can use an additional parameter
to parameterise the behaviour of cyclical functions.
All keys function as a master input
You can use this action to specify one of the two or
four inputs as the master input. When any key is
pressed, the action which has been parameterised for
the master key is carried out.
