ICR890 High-end CCD Camera System

Electrical installation

5.4.4 Data interface CAN 1-IN/OUT

General conditions of the CAN interface

The SICK-specific CAN-SENSOR network is based on the CAN bus, which is structured in line

topology.

Tab. 5-12 shows the maximum permissible CAN bus length, depending on the selected data

transfer rate.

Tab. 5-13 shows the maximum permissible overall length of all stub cables, depending on

the data transfer rate. This overall length must not be exceeded. The maximum length of

each individual stub cable must not exceed 6 m (19.7 ft).
