The LogiPanel GEL 8819 can be programmed in the LB-
Flex plain-text programming language which is based on
IEC standard 1131-3, „Structured text“.
The plain-text programming language makes use of
natural language elements which - when used in conjunc-
tion with some basic rules - will lead in a short time to
executable programs.
Applications can therefore be programmed in a clear and
almost self-explaining way by means of the simple and
more complex instructions required for LogiPanel pro-
gramming.
The LB-Flex language makes use, among other things, of
elements and notations used in algebra and in higher
programming languages and offers the possibility of not
only checking an input status, but also of performing the
complex calculation of nominal positions.
Programming language elements
•
mnemonic and symbolic variables representing the
following types of data: bit, byte, word, dword and
pointer
•••••
constants and symbolic constants
•••••
arithmetical and logical operators, bit and
address operators
•••••
sequence control instructions and
program structuring instructions
•••••
mathematical functions
•••••
conversion functions
•••••
operating and monitoring functions
•••••
specific device functions
•••••
travelling and positioning functions
•
access functions for converter variables
•
INCLUDE instructions operating on definition
and library files
The use of symbolic variables and constants with user-
defined denominations ensures perfect transparency of
your programs.
