Skip Blocks; Overstore - Siemens SINUMERIK 840D sl Operating Manual

6.8.2

Skip blocks

You can skip program blocks that are not to be executed every time the program runs.
The skip blocks are identified by placing a "/" (forward slash) or "/x (x = number of skip level)
character in front of the block number. You have the option of hiding several block sequences.
The statements in the skipped blocks are not executed. The program continues with the next
block, which is not skipped.
The number of skip levels that can be used depends on a machine datum.

Note
The "Program Control - Skip Blocks" window is only available when more than one skip level
is set up.

Overstore

With overstore, you have the option of executing technological parameters (for example,
auxiliary functions, axis feed, spindle speed, programmable instructions, etc.) before the
program is actually started. The program instructions act as if they are located in a normal part
program. These program instructions are, however, only valid for one program run. The part
program is not permanently changed. When next started, the program will be executed as
originally programmed.
After a block search, the machine can be brought into another state with overstore (e.g. M
function, tool, feed, speed, axis positions etc.), in which the normal part program can be
successfully continued.
