Displaying A Basic Block - Siemens SINUMERIK 840D Operating Manual

4.4.2

Displaying a basic block

If you want precise information about axis positions and important G functions during testing
or program execution, you can call up the basic block display. This is how you can check,
when using cycles, for example, whether the machine is actually traversing.
Positions programmed by means of variables or R parameters are resolved in the basic
block display and replaced by the variable value.
You can use the basic block display both in test mode and when machining the workpiece on
the machine. All G code commands that initiate a function on the machine are displayed in
the "Basic Blocks" window for the currently active program block:
● Absolute axis positions
● G functions for the first G group
● Other modal G functions
● Other programmed addresses
● M functions
