3.1 Settings inside the encoder
The encoder node address and bus termination must be
configured during commissioning of the device. This is done by
removing the back cover, i.e. screwing off the three screws at the
rear of the encoder.
3.1.1 Node address
The node address of the encoder can be set via two decimal
rotary switches located inside the back cover. The weighting, x10
or x1 are specified beside the switches. Permissible address
range is between 0 and 99 but the lower addresses 0 to 2 are
usually used by the master and not recommended to be used by
the device. Each address used in a PROFIBUS network must be
unique and may not be used by other devices.
The device address is only read and adopted when the encoder
power supply is switched on. A restart of the encoder is therefore
required in order to adopt changes done to the address settings.

Example : If the node address shall be set to 85, the left (x10)
switch shall be set to 8 and the right (x1) switch shall
be set to 5.
