Glossary
User memory
All programs and data, such as part programs, subroutines, comments, tool offsets, and zero
offsets/frames, as well as channel and program user data, can be stored in the shared CNC
user memory.
User Program
User programs for the S7-300 automation systems are created using the programming
language STEP 7. The user program has a modular layout and consists of individual blocks.
The basic block types are:
● Code blocks
● Data blocks
User-defined variable
Users can declare their own variables for any purpose in the → part program or data block
(global user data). A definition contains a data type specification and the variable name. See
→ System variable.
Variable definition
A variable definition includes the specification of a data type and a variable name. The
variable names can be used to access the value of the variables.
Velocity control
In order to achieve an acceptable traverse rate in the case of very slight motions per block,
an anticipatory evaluation over several blocks (→ Look Ahead) can be specified.
WinSCP
WinSCP is a freely available open source program for Windows for the transfer of files.
Working area
Three-dimensional zone into which the tool tip can be moved on account of the physical
design of the machine tool. See → Protection zone.
Working area limitation
With the aid of the working area limitation, the traversing range of the axes can be further
restricted in addition to the limit switches. One value pair per axis may be used to describe
the protected working area.
1106
These blocks contain the STEP 7 commands.
These blocks contain constants and variables for the STEP 7 program.
