FB name
Identifies fhe FB unambiguously. FBs with the same function are distinguished by a number behind
the name.
Every FB is defined by a selection number. For calculating the FB, the selection number must be input
into the processing table. ( 3−12)
The selection numbers are listed in selection list 5.
Example:
(FCNT1, see Fig. 3−1)
l FCNT1 ¢ selection number 6400 (selection list 5).
Input symbol
Designates the signal type which is allowed as signal source for this input. ( 3−5)
Tip!
Only linked inputs can be configured.
Input name
Consists of the FB name and a designation. Inputs with the same function are distinguished by the
number that is added to the designation.
