Connecting up function blocks (BICO system)
BICO system is the term used to descrbe the method of creating
connections between function blocks. This is performed with the aid of
bi
nectors and
co
nnectors. The name
BICO
system is derived from
these two terms.
A connection between two function blocks consists of a connector or
binector on the one side, and a BICO parameter on the other side. The
connection is always made from the point of view of the input of a
function block. You must always assign an output to an input.
Assigment is made by entering in a BICO parameter the number of the
connector or the binector from which the required input signals are read
in. You are allowed to enter the same connector and binector numbers
several times in different BICO parameters and thus use output signals
of one function block as input signals for several other function blocks.
Example:
In the following figure, connector K0152 is connected to connector
parameter P228. For this purpose, you must assign the number of
connector K0152 as the value to the connector parameter P228, i.e. in
this case 152.

e.g. P228.01 = 0152
