Value range
0x00 FreeRunning: No restriction to port cycle
0x01: FixedValue: The port cycle timing is fixed to a specific value (see
parameter: Cycle time)
0x02: MessageSync: The port cycle timing is restricted to the synchro-
nous start of all messages on all IO-Link ports of this master
Default value

•
Free Running: No limitation of the port cycle time, i.e. the master communicates with the cycle time
that was communicated to it by the device via the “MinCycleTime” communication parameter.
•
The port cycle time is specified by the cycle time parameter (see below).
•
MessageSync: The port cycle time is adjusted so that all IO-Link messages on ports X1 to X4 start syn-
chronously on a master, i.e. all communicate using the same cycle time. The maximum “MinCycle-
Time” of all connected devices (on one master) is the decisive factor here. This is used for all devices.

This parameter contains the requested or current value of the cycle time. If this value is to be binding as
the master cycle time for communication with a device at the port, the “Port cycle” parameter (see above)
must also be configured using “FixedValue”.
IO-Link Device Validation
The following four parameters (inspection level / vendor ID / device ID / serial number) can be used to vali-
date a connected IO-Link device. IO-Link communication is only started if the data match. The “Inspection
level” parameter can be used to determine whether or not validation should take place and which data
should be validated.
