Word order
If there are several instructions in a block, the following order is recommended:
N... G... X... Z... F... S... T... D... M... H...
Note regarding block numbers
First select the block numbers in steps of 5 or 10. Thus, you can later insert blocks and
nevertheless observe the ascending order of block numbers.
Block skip
Blocks of a program, which are to be executed not with each program run, can be marked by
a slash / in front of the block number.
The block skip itself is activated via Operation (program control: "SKP") or by the
programmable controller (signal). A section can be skipped by several blocks in succession
using " / ".
If a block must be skipped during program execution, all program blocks marked with " / " are
not executed. All instructions contained in the blocks concerned will not be considered. The
program is continued with the next block without marking.
