Modes and Functions
3.6 Frequency output mode
Setting and changing the On-delay
● Permanent update
The On-delay can be controlled permanently using the control interface. MODE_SLOT bit
has to be set (permanent-update); LD_SLOT must be the value 2 (for On-delay). Set the
On-delay as a value between 0 μs and 85,000,000 μs in the field SLOT. The unit is
always microseconds.
● Single update
Set the On-delay as a value between 0 μs and 85,000,000 μs in the configuration
parameters, the unit is always microseconds. Alternatively, perform a single update using
the control interface. MODE_SLOT has to be cleared (single-update); LD_SLOT must be
the value 2 (for On-Delay). Set the On-delay as a value between 0 μs and 85,000,000 μs
in the field SLOT.
If you change the On-delay value during the output sequence, the new On-delay is activated
at the next output sequence.
For more details about the use of the SLOT parameter, see Slot parameter handling
(Page 113).
Isochronous mode
General information is available in the "Function: Isochronous mode (Page 86)" topic.
Isochronous mode does not have any influence on the functionality of Frequency output
operating mode.
If you want to synchronize the output sequence with T
to "Input" and the frequency output sequence starts at T
