ReqCycleTime
Name:
CfO_ReqCycleTime01 to CfO_ReqCycleTime04
This register is used with free-running (asynchronous) IO-Link communication. It contains the explicitly defined
cycle time for the IO-Link query in µs.
Information:
•
In free-running mode, no net time data points are permitted to be used except for CycleEnd-
Nettime.
•
If the cycle time predefined for IO-Link communication falls below the device's minimum cycle
time, the IO-Link data is queried using the device's minimum cycle time.
•
For efficient IO-Link communication, the configured query time should correspond to the spec-
ified IO-Link cycle times. If a value is unsuitable, the next suitable cycle time is used automat-
ically.

4.26.5.9.5 IO-Link - General
The following registers are used for general communication. They are mainly used for repair status and runtime
control.
4.26.5.9.5.1 Digital SIO outputs
Name:
DigitalOutput01 to DigitalOutput04
DisablePowerSupply01 to DisablePowerSupply04
If a channel is being operated in SIO mode (SIO output), this register can be used to control the SIO output of the
IO-Link channel. It is also possible switch on/off the supply for each IO-Link channel individually.
