Each function block has a function block number (FB number) by which
it can be clearly identified. With the FB number, you can define which
time slot can be used for processing a large number of function blocks.
For this purpose, each function block is allocated an indexed parameter
which contains the relevant FB number in its parameter number and its
parameter index.
Example:
U950.01 is the code of FB number 001
U953.50 is the code of FB number 250
U953.99 is the code of FB number 299
U954.74 is the code of FB number 374
The parameter for selecting the time slot as well as the corresponding
factory setting are indicated in the function diagrams for each function
block. This data takes the form of an ellipse in order to distinguish it
optically from the other elements of a function block.
In addition to the time slot, the processing sequence can also be
determined for most of the function blocks.
Connectors and binectors are elements which are used to exchange
signals between individual function blocks. They are each cyclically
filled by function blocks with one signal value. Other function blocks can
then call up these values, depending on parameterization.
Connectors can be likened to storage locations which are used to
archive "analog" signals. They are clearly designated. Each connector
designation comprises the connector name, the connector number and
an identification letter.
The identification letter depends on the numerical representation:
♦ K
Connector with word length (16 bit)
♦ KK Connector with double-word length (32 bit, increased accuracy)
The connector number always has four digits.
