4.15.22.10.8.2 Switching mask after the delay time has expired
Name:
DigitalOutput01DelayEnable to DigitalOutput08DelayEnable
These registers create the mask for OutputDelay. They define which outputs are switched to the bit string for the
OutputDelayed register after the delay time has expired.
Data type

4.15.22.10.8.3 Setting the delay
Name:
OutputDelayTime
This register can be used to set the delay in 100 μs steps.
After the delay time has expired, the digital outputs are adjusted according to the switching mask (register 6) and
the delayed output pattern (register 4).
Data type
Value
USINT
0 to 255 (in 100 μs steps)

The value 0 disables processing
4.15.22.10.9 Minimum cycle time
The minimum cycle time defines how far the bus cycle can be reduced without communication errors occurring.
It should be noted that very fast cycles decrease the idle time available for handling monitoring, diagnostics and
acyclic commands.
Minimum cycle time
Standard function model
100 μs
Bus controller function model
150 μs
4.15.22.10.10 Minimum I/O update time
The minimum I/O update time defines how far the bus cycle can be reduced while still allowing an I/O update to
take place in each cycle.
Minimum I/O update time
Function model 0
Equal to the minimum cycle time
Function model 1
Equal to the minimum cycle time
