Detailed Description
2.9 Program control
To avoid bottlenecks in the NCK performance, the basic block display is deactivated
automatically. A display block containing the string "..." is generated as character for missing
display blocks.
In single-block mode, all the display blocks are always generated.
Structure for a DIN block
Basic structure of display block for a DIN block
• Block number/label
• G function of first G group
• Axis positions
• Other modal G functions
• Other addresses as programmed.
The display block for the basic block display is directly derived from the programmed part
program blocks according to the following rules:
• Macros are expanded.
• Skip identifiers and comments are omitted.
• Block number and labels are transferred from the original block, but omitted if DISPLOF is
• The number of decimal places is defined in display machine data MD 9004, MD 9010 and

Note
The modulo correction is omitted for modulo axes, which means that positions outside the
modulo range can be displayed. It also means that the basic block display differs from the
position display in which values are always moduloconverted.
