Wo rd order
If there are several instructions in a block, the following order is recommended:
N ... G... X... Z... F... S... T... D... M... H...
N o te 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.
Bl ock skip
Blocks of a program, which are to be executed not with each program run, can be m arked by a slash / in front of the block
number.
The block skip itself is activated via Op e ration (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.
C omment, remark
The instructions in the blocks of a program can be explained using comments (remarks). A comment always starts with a
semicolon " ; " and ends with end-of-block.
Comments are displayed together with the contents of the remaining block in the current block display.
Me ssages
Messages are programmed in a separate block. A message is displayed in a special field and remains active until a block
with a new message is executed or until the end of the program is reached. Up to 6 5 characters can be displayed in
message texts.
A message without message text cancels a previous message.
