Encoder with ProfiNet interface

An IO device is addressed within ProfiNet (and also possibly by external Ethernet

components) through its IP address�
Data can be transferred (process data) from the IO controller to the IO device (and

vice versa) cyclically� Apart from this, acyclic parameters can be exchanged during

setup of the IO device or by the use of PLC programming blocks during operation�

4 Functions and features

●

Integrated bootloader for firmware upgrades

●

Round axis functionality

●

Neighbouring detection (when replacing the device)

●

Device identification via LEDs

●
