Preconditions and
configuration
The “Edit workpiece” softkey enables you to edit a workpiece in the
step editor.
The program directory offers the following files for channel
assignment:
• Select a workpiece directory in which a DAT, JOB or MPF (with
INIT/START) file with the same name is stored.
• Directly select a DAT file
• Directly select a JOB file using Select instructions
• Directly select a MPF file using INIT/START instructions.
It is also possible to create the channel assignment under a workpiece
directory, e.g., for certain sequences on the machine stored in
separate channel programs (setup, remove stock, measure…).
In this case, you are recommended to store the most frequently used
scenario in the file workpiecename.DAT, *.JOB or *.MPF. If you only
want to open the setup scenario, select Setup.name.DAT, .JOB or
.MPF in the data selector.
Edit
workpiece
To activate the step sequence display, press the “Edit workpiece”
softkey and
• Select the workpiece in the workpiece directory WPD
• Select the JOB list
• <Workpiece name>.MPF is available (and no JOB list or DAT file
with the same name).
If these preconditions are met, the DAT file is created or updated for:
• Section [Environment*] → Multi-channel program display and
editing
• Section [TimeData_*] → Recorded time for time-proportional
step sequence display
• Basis for section-by-section simulation (see Chapter “Program
simulation”)
Settings.
If step sequence display is active (single-channel and multi-channel)
you can use the softkey to select whether, e.g., the times are to be
specified in the step sequence displays next to the step identifiers.
The settings become active immediately.
Templates As with the JOB list, the internal file workpiece name.DAT for
coordinating the multi-channel step sequence display and simulation
can also be created from a template.
A workpiece name.DAT file is only created/entries entered in this file if
the files were selected via workpiece name.WPD, workpiece
name.JOB or workpiece name.MPF.
It is updated upon selection of a multi-channel program and the "Edit
workpiece" softkey and when timing is active.
