8.8 Programmable output duration
Function
User-specific auxiliary functions, for which the output behavior "Output duration of an OB1
cycle (slow acknowledgement)" was parameterized, can be defined for individual outputs via
the parts program guide QU (Quick) for auxiliary functions with quick acknowledgement.
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 for the output of the auxiliary functions M100 and M200 in a parts program.
The output behavior of the auxiliary functions is parameterized as follows:
● M100
– Output duration one OB1 cycle (slow acknowledgment)
– Output during motion
● M200
– Output duration one OB1 cycle (slow acknowledgment)
– Output prior to motion
