Fig. 8-1 Structure of an FB using the example of FCNT1
Name of the FB
Identifies the FB clearly. The name of the FB is followed by a number distinguishing the function of
the FB.
A selection number defines every FB. The input of the selection number into the processing table
is always required for the calculation of theFB.

Example:
(FCNT1, see Fig. 8-1)
• FCNT1 ≡ selection number 6400 (selection list 5).
Input symbol
Designates the signal type which is allowed as a source for each input.

Tip!
Inputs which are not linked cannot be configured.
Name of the input
Consists of the FB name and a designation. Thedesignations of the inputs are followed by a number
distinguishing the functions of the input.
Configuration code
Configurestheinput withasignalsource(e.g.terminalsignal,controlcode,outputofaFB, ...).Inputs
with identical codes are distinguished by the attached subcode (Cxxxx/1). These codes are
configured by their subcodes.
It is not possible to connect one input with several signal sources.
