The backup battery ensures that the -> user program is reliably
backed up in the -> CPU against mains failure and that fixed data
areas and markers, times and counters are kept in non-volatile
memory.
The backup memory enables buffering of memory areas of the ->
CPU without a buffer battery. Buffering can be performed for a
configurable number of times, counters, markers and databytes.
Axis whose setpoint or actual value position forms the basis of the
calculation of a compensation value.
Cartesian coordinate system which is mapped by transformation onto
the machine coordinate system.
In the -> parts program, the programmer uses the axis names of the
basic coordinate system. The basic coordinate system exists in
parallel to the -> machine coordinate system when no ->
transformation is active. The difference between the systems relates
to the axis identifiers.
Rate of data transfer (Bit/s).
Workpiece as it is before a part is machined.
"Block" is the term given to any files required for creating and
processing programs.
A section of a -> parts program terminated with a line feed. A
distinction is made between -> main blocks and -> subblocks.
For testing part programs or following interruption of machining, it is
possible to select any point in the part program using the block search
function in order to start or resume at this point.
Loading the system program after power on.
With the B-Spline, the programmed positions are not interpolation
points, as they are just "control points" instead. The generated curve
only runs near to the control points, not directly through them (optional
1st, 2nd or 3rd order polynomials).
A bus connector is an S7-300 accessory part which is supplied
together with the -> I/O modules. The bus connector expands the ->
S7-300 bus from the -> CPU or an I/O module to the neighboring I/O
module.
