HW Config
SIMATIC S7 tool for the configuration and parameterization of hardware components within
an S7 project
Identifier
In accordance with DIN 66025, words are supplemented using identifiers (names) for
variables (arithmetic variables, system variables, user variables), subprograms, key words,
and words with multiple address letters. These supplements have the same meaning as the
words with respect to block format. Identifiers must be unique. It is not permissible to use the
same identifier for different objects.
Inch measuring system
Measuring system which defines distances in inches and fractions of inches.
Inclined surface machining
Drilling and milling operations on workpiece surfaces that do not lie in the coordinate planes
of the machine can be performed easily using the function "inclined-surface machining".
Increment
Travel path length specification based on number of increments. The number of increments
can be stored as → setting data or be selected by means of a suitably labeled key (i.e. 10,
100, 1000, 10000).
Incremental dimension
Also incremental dimension: A destination for axis traversal is defined by a distance to be
covered and a direction referenced to a point already reached. See → Absolute dimension.
Intermediate blocks
Motions with selected → tool offset (G41/G42) may be interrupted by a limited number of
intermediate blocks (blocks without axis motions in the offset plane), whereby the tool offset
can still be correctly compensated for. The permissible number of intermediate blocks which
the controller reads ahead can be set in system parameters.
Interpolator
Logic unit of the → NCK that defines intermediate values for the motions to be carried out in
individual axes based on information on the end positions specified in the part program.
