4 LOGO! functions

Organization

LOGO! provides you with various elements in programming
mode. In order to maintain the overview, we have orga-
nized the elements in 'Lists'. These lists are:
S
±Co: Connector list (Connector)
(see Chapter 4.1)
S
±GF: List of the basic functions AND, OR, ...
(refer to Chapter 4.2)
S
±SF: List of the special functions
(refer to Chapter 4.4)
S
±BN: List of reusable blocks configured in the circuit
program

List contents

All lists show the elements available in LOGO! Usually, this
includes all connectors, basic functions and special func-
tions the LOGO! knows. This includes all the blocks you
have created in LOGO! by the time you call the ±BN list.

If not all is shown

LOGO! does not show all elements if:
S
No further blocks may be added.
This is either an indication of insufficient memory space
or that the maximum number of blocks has been
reached.
S
A specific block's memory space requirement would ex-
ceed the space available in LOGO!
See Chapter 3.8.
