Siemens SINUMERIK 840D sl Function Manual page 119

A distinction is made between single-cycle and multi-cycle actions. Examples are:
● Single-cycle actions: Auxiliary function output, value assignments
● Multi-cycle actions: Traversing motions of axes and spindles
Each block of a technology cycle requires at least one interpolator clock cycle.
Processing mode: ICYCOF
All actions of all blocks of a technology cycle are initiated in parallel in the ICYCOF processing
mode.
NC program as a part program
If an NC program is executed as a part program, the ICYCOF and ICYCON commands have
no effect.
Syntax
In the action part of a synchronized action
ID=1 <condition part> DO [ICYCOF] <technology cycle 1> [ICYCOF |
ICYCON] <technology cycle 2> ...
As property of an NC program
PROC <name> [ICYCOF | ICYCON]
Within an NC program
PROC <name>
N10 ...
N20 [ICYCOF | ICYCON]
N90 ...
N100 [ICYCOF | ICYCON]
N110 ...
