Installation

Settings

The unit and the parameters are set via the operating elements (→ 6.2).

For selected units, setting can be done via IO-Link (→ 6.1).

6.1 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. To set the sensor via IO-Link, the parameter [L-r] must be changed from [local] to [remote] via IO-Link.
