SICK MAX Series

Parameters specific to the CAN bus, such as baud rate and node ID, are also configured
and saved via the LSS service. Both the baud rate and node ID of the encoder must be
configured for operation in the specific CAN bus implementation.
Setting the node ID
NOTE
When programming the node ID, only one device or node must be connected.
Every device or node must be assigned a number (node ID). This number is used to
identify the node within the CANopen network. Each node ID must be unique. The
CANopen node ID must be in the range of 1 - 127, and can be preset when ordering. To
ensure error-free operation of the network, the ID of every node in the CAN bus must be
unique.
The node ID of the device can be set using the following command sequence:

Sensor 0x7e4 11; 00; 00; 00; 00; 00; 00; 00 Controller
*
Node address values can be between 1 and 127 (for example 125).
A change in node address is effective immediately.
To permanently save the node address, the following command must be sent:

Setting the baud rate
The baud rate indicates the speed of operation of the device and also the entire CAN
bus. The device and entire network must be set to the same baud rate.
The maximum baud rate is limited by the cable length used for the CAN network as a
whole. The device is delivered with a preset, order-dependent baud rate. If this baud
rate needs to be changed, it can be configured via the LSS.
