Description

 

 

 

Opto-isolated CAN interface using a RJ45 connector.

 

 

 

 

 

CAN offers serial communications over a two wire twisted pair cable up to maximum length of 500m (1640ft). It offers very high communication reliability in an industrial environment; the probability of an undetected error is 4.7x10-11. CAN is optimized for the transmission of small data packets and therefore offers fast update of I/O devices (peripheral devices) connected to the bus. The maximum (default) transmission rate on NextMove ES is 500Kbit/s.

Correct operation of CAN can only be achieved with screened/shielded twisted-pair cabling. For improved noise immunity, CAN+ and CAN- must form a twisted pair with the shield connected to the connector backshell, as shown in Figure 13. A range of suitable CAN cables are available from Baldor, with catalog numbers beginning CBL004-5...
