Structured Text language is a sophisticated algorithmic type language, and is
particularly well suited for programming complex arithmetic functions, table
operations, message handling, etc.
Structured Text language can be used to directly transcribe an analysis based on an
organization chart, and is structured into expressions composed of a series of
instructions organized in lines.
There is no limit to the number of characters an instruction line may contain (the only
limit is the program memory available for the Modicon M340, Premium
Quantum platforms, except on TSX P57 10 40 processors, where the limit is 64 Kb).
The length of the section is only limited by the size of the application memory.
Four preformatted expression structures can be called up directly from the toolbar:
b
b
REPEAT…UNTIL…END_REPEAT;
b
b
The operands used in the expressions are bit variables, word variables or variables
linked to function blocks.
To make the expressions easier to read, different colors are used to identify objects,
language key words and program comments.
