Profibus Interface
The Profibus Interface for the sensor operation control is identical with the Standard DP V0 Profibus (with pe-
ripherals decentralized) where V0 designates the version. Telegrams are byte-oriented. A byte is also referred
to as an Octet in Standard Profibus terminology. From a user’s point of view, the following types of telegrams
are required to accomplish communication:
- cyclical data exchange telegrams (DataEx)
- diagnostic telegrams
- parameter setup telegrams
The various Profibus slaves of identical or similar functionality are described in profiles. These make it easier
for users to work with PB slaves from different manufacturers, which provide identical functionality.
For operation of the sensor in Profibus mode, the encoder profile of the Profibus (order no. 3062 of PNO) is
supported. The sensor works as a linear encoder in this case. Within the available encoder profile capabili-
ties, the sensor can work as a class1 or class2 encoder (recommended). All versions are accomplished via a
GSD file. In addition to specific profile data, the sensor provides specific device settings. These concern laser
control and diagnosing aspects.

Slave Address Setting
Slave address 4 is factory-set.
Changes can be made via the Profibus Master. A desired address can be assigned using the SSA (Set Slave
Address) signal.
