IO-Link Interface
The IO-Link interface is available in both designs (housing with fixed cable outlet or with round connector).
8.8.1
Connections
In order to comply with the IO-Link standard, the housing variant with fixed cable outlet is supplied with
a 4-pin M12 (male) round connector with the IO-Link standard pin assignment.
Pin assignment see
For versions with IO-Link and additional incremental output (see
9) the 4-pin IO-Link standard round
connector is no longer sufficient. Here, the sensor cable is supplied with open cable ends as standard.
Optionally, the cable can be supplied with a 12-pin M12 (male) round connector
(see
Connection options
"RCM0").
Pin assignment see
For the housing version with round connector, an additional DKA cable with the M12 round connector
mentioned above and identical pin assignment is available as an accessory (see
For this version no incremental outputs (see option
9) are available.

Functional Description
The IO-Link interface integrated in the sensor enables continuous communication between the system controller
and the field level.
Position information and errors are independently reported to the controller and can be easily viewed.
Conversely, format adjustments, for example, can be set up more easily.

Process Data
EMAX-IO cyclically transmits a measurement value via the IO-Link interface.

8.8.4
Set Zero
1.
Move the EMAX-IO sensor to the desired position.
2.
Write E0 (16) on Index 2 / Subindex 0 via system command “Set Zero”.
3.
EMAX-IO calculates the offset so that zero is output at the approached position.
