5 Settings
The unit and the parameters are set via the IO-Link interface (→ 5.1) or the
teach button (→ 5.2).
5.1 IO-Link
This unit has an IO-Link communication interface which enables direct access to
process and diagnostic data. In addition it is possible to set the parameters of the
unit while it is in operation. Operation of the unit via an IO-Link interface requires
an IO-Link master.
With a PC, suitable IO-Link software and an IO-Link adapter cable communication
is possible when the system is not in operation.
The IODDs necessary for the configuration of the unit, detailed information about
process data structure, diagnostic information, parameter addresses and the
necessary information about the required IO-Link hardware and software can be
found at www.ifm.com.
