2.4 Programmable output duration
2.4
Function
The user-specific auxiliary functions for which the output behavior: "Output duration one OB1
cycle (slow acknowledgment)" was parameterized, can be defined for each output via the
part program instruction QU (quick) for auxiliary functions with quick acknowledgment.
Syntax
An auxiliary function with quick acknowledgment is defined in a part program block with the
following syntax:
< type > [ < address extension > ] = QU(< value >)
Example
Different behavior on the output of auxiliary functions M100 and M200 in a part program. The
output behavior of the auxiliary functions is parameterized as follows:
• M100
• M200

Example of auxiliary function output
– Output duration one OB1 cycle (slow acknowledgment)
– Output during motion
– Output duration one OB1 cycle (slow acknowledgment)
– Output prior to motion
Auxiliary Function Output to PLC (H2)
