Horizontal softkeys
The workpiece or program overview is displayed. In this area it is
possible to select programs for execution.
Vertical softkeys
The "Current block" window is also displayed.
The current block is highlighted while the program is running.
The name of the program to which the blocks on the screen belong is
output in the window header.
When you press the "Program level" softkey, the window headed
"Program level" appears instead of the "Current block" window.
The program nesting depth (P = number of passes) is displayed.
In program operation it is possible to toggle between the "Program
level" and "Current block" displays.
Seven program blocks of the current program are displayed together
with the current position in the part program.
The 7-block display always shows the programmed part program and
not the actual program run. In particular with subroutine calls, the
block displayed as next block after the UP is only the block which is
executed after the UP call, not the first block of the subprogam
(program execution).
Further information
The other softkeys are described in the sections below.
