4.6.9 Accelerated external block search
Function
The block search function allows you to run the part program forward
until you reach the block you require.
You can use the "External without calc." softkey in the "Search
position" and "Search pointer" menus to start a fast block search in
programs that are processed by an external device (local hard disk or
network drive).
You can define the search destination by
· Directly positioning the cursor to the destination block, or
· Specifying a block number or a line number.
Block search sequence:
Only those programs and program parts which are needed in order to
reach the specified search target and to continue program execution
are transferred to the NC. This applies to the following:
· "Execution from external source" function
· Execution of EXTCALL instructions
Example:
The following search destinations are entered in the Block search
menu:
Search target 1 .......................................................................................
Search target 2 .......................................................................................
Search target 3 .......................................................................................
