Fig. 7-1 Structure of a FB using the example of FCNT1
Name of the FB
Identifies the FB unambigeously. FBs with the same function are distinguished by a number behind
their names.
Every FB is defined by a selection number. The input of the selection number into the processing
table is always required for the calculation of the FB.
(

FCNT1 selection number 6400 (selection list 5).
Input symbol
Designates the signal type which is allowed as signal source for this input.

Note!
You cannot configure inputs which are not linked.
Input name
Consists of the FB name and a designation. Inputs with the same function are distinguished by a
number behind their designations.
Configuration code
Configures the input with a signal source (e.g. terminal signal, control code, output of a FB, ¡).
Inputs with identical codes are distinguished by the subcode. The subcode is attached to the code
(Cxxxx/1).These codes are configured by their subcodes.
It is not possible to connect an input with several signal sources.
