1.5 Conventions used
This Manual uses the following conventions to distinguish between the different types of
information:

Key words Courier bold ...starts with FUNCTION and ends with END FUNCTION.
Important note Caution!
Do not use the Online Controller inhibit command for an emergency stop via
the PC as this command is sent to the controller subject to a delay.
Tip TIP!
Hover the mouse pointer over a symbol on the toolbar to display a tooltip indicating
the corresponding command.
Variable names
The conventions used by Lenze for the variable names of its system blocks, function blocks and
functions are based on what is known as "Hungarian Notation". This allows you to identify the
most important properties (e.g. the data type) of a variable immediately by means of its name,
e.g. DIGIN_bIn1_b.
You will find information about the conventions in the appendix of the DDS Online
documentation "Introduction to IEC1131-3 programming”.
