Constants
B
Type designation not permitted
DB x
Data blocks. The C DBx operation is
executed.
FB
x
Function blocks (permissible without
parameters only) are called
unconditionally (JU..x).
PB x
Program blocks are called
unconditionally (JU..x).
SB x
Sequence blocks are called
unconditionally (JU..x).
OB x
Organization blocks are called
unconditionally (SPA..x).
T
Type designation not permitted
T
Timer. The time should be assigned
parameters as data or be
programmed as a constant in the
function block.
C
Counter. The count should be
assigned parameters as data or be
programmed as a constant in the
function block.

Calling a Function Block
Function blocks are stored like other blocks under a specific number (e.g. FB47) in internal pro-
gram memory. Numbers 240 to 251 are reserved for integral FBs and can therefore not be used for
user-written FBs! Numbers 238 to 239 are also reserved for integral FBs; however, these FBs can be
renumbered (see Chapter 11).
FB calls can be programmed in all blocks except data blocks.
