Commissioning
7.1
Overview of commissioning steps
■
Connect the voltage supply.
■
Commission the sensor using the factory settings.
■
Configure the sensor.
7.2
Commissioning the sensor for the first time
Establish voltage supply: When the sensor voltage supply is correct, the green “PWR”
LED lights up.
7.3
First step to commissioning with CANopen
7.3.1
CANopen overview
Communication profile
The CANopen communication profile (documented in CiA DS-301) regulates how the
devices in a CANopen network exchange data.
CANopen in the OSI model
The CANopen protocol is a standardized Layer 7 protocol for the CAN bus. This layer is
based on the CAN Application Layer (CAL).

Architecture
CANopen is an asynchronous, serial fieldbus. The GLS100 is inserted into the bus via
a stub cable in a star configuration. It needs to be terminated at the beginning and at
the end of the fieldbus. A passive 120 Ω bus terminating resistor is sufficient for this
purpose.
