If an interruption point is available on the NC, you can switch back and
forth between the program levels.
Start search without calculation for external programs.
Define search target in search pointer:
Once the "search pointer" softkey has been pressed, a screen form
with the program pointer is displayed.
This contains input fields for program name, search type (block
number, text, ...) and search target (content). The cursor is
positioned in the input field for the "search type".
Type 1 (block number) and type 5 (line number) are possible as
search target types.
Start search without calculation for external programs.
Function
The NC is operated in Program test mode for this block search, so
that interactions between channel and synchronous actions and
between multiple channels are possible within an NCU.
The "Block search in Program test mode" enables a program advance
up to the desired point of the part program with the following functions:
During "Block search in Program test mode", the NC outputs all
auxiliary functions to the PLC and the part program commands for
channel coordination (WAITE, WAITM, WAITMC, Axis replacement,
Write variables, etc.) are carried out by the NC.
• This means that the PLC is updated during this block search and
• Machining operations involving multiple channels are executed
correctly within the block search.
You can select the function via the "Prog. test Contour" softkey in
the "Search position" and "Search pointer" menus.
You can define the search target by
• Directly positioning the cursor on the target block, or
• Using the input fields "Program name", "Search type" and "Search
target".
