Connection/Logic
With the function
Connection/Logic
it is possible to connect the switching of
the output with certain conditions. Two connection objects are available:
At first the communication object
Logical connection 1
is evaluated with the
communication object
Switch
. The result of this is then logically linked with
the communication object
Logical connection 2
.
The following logic functions are possible:

is only
allowed through if the GATE
(connection) is open.
Otherwise the receipt of the
object
Switch
is ignored.
