Explanations of the example
Open the default signal interconnection for BICO parameterization
The default setting P0701 = 1 indicates the following internal signal interconnection:
Terminal 5
r0722.0
P0840
ON/
OFF1
DI 0
Figure 1-4 Default parameterization
The setting P0701 = 99 means that a pre-assigned signal interconnection is disconnected
and therefore the connection opened for BICO parameterization.
Terminal 5
r0722.0
P0840
ON/
OFF1
DI 0
Figure 1-5 BICO parameterization
When P0701 = 99, the binector input of the ON/OFF1 function (P0840) is available for
activation by a signal source other than r0722.0 (in this case r2852).

Principle of connecting functions by means of BICO technology
A connection between two functions comprises a connector/binector and a BICO parameter.
Connections are always established with respect to the input of a particular function, which
means that the output of an upstream function must always be assigned to the input of a
downstream function. The assignment is always made by entering the number of the
connector/binector from which the required input signals are read in a BICO parameter.
With this functional logic in mind, where does the signal come from?
