ICP DAS has been developing various CAN products for several years, including PCI interface, converter, PAC and slot module CAN products. ICP DAS holds CAN conference, exhibition and training course all of the world. We also help customers to resolve various CAN technology problems. In addition, we can provide CAN bus solution for our customers.

CAN Bus Features
The Controller Area Network (CAN) is a serial communication way, which efficiently supports distributed real-time control with a very high level of security. It provides the error process mechanisms and message priority concepts. These features can improve the network reliability and transmission efficiency. Furthermore, CAN supplies the multi-master capabilities, and is especially suited for networking “intelligent” devices as well as sensors and actuators within a system or sub-system.

Multi-master
When the bus is free any unit may start to transmit a message. The unit with the message of highest priority to be transmitted gains bus access.

Safety
In order to achieve the utmost safety of data transfer, powerful measures for error detection, signaling and self-checking are implemented in every CAN node. When transmitting data, many measuring algorithms including Cyclic Redundancy Check, Message Frame Check and Bit Stuffing have been taken.

Speed & Distance

Baud (bit/sec)	Ideal Bus Length
1M	25
800K	50
500K	100
250K	250
125K	500
50K	1000
20K	2500
10K	5000

Arbitration
If two or more nodes start transmitting messages at the same time, the arbitration mechanism is applied to guarantee that one of these messages can be sent successfully according to the priority.

Priorities
The CAN IDENTIFIER defines a static message priority during bus access.

Bus length [m]	Bus cable		Termination resistance [Ω]	Baudrate [kbit/s]
Bus length [m]	Length-related resistance [mΩ/m]	Wire cross-section [mm²]	Termination resistance [Ω]	Baudrate [kbit/s]
0 ~ 40	70	0.25 ~ 0.34	124	1000 at 40 m
40 ~ 300	<60	0.34 ~ 0.6	150 ~ 300	>500 at 100 m
300 ~ 600	<40	0.5 ~ 0.6	150 ~ 300	>100 at 500 m
600 ~ 1000	<26	0.75 ~ 0.8	150 ~ 300	>50 at 1 km

Wire cross-section [mm²]	Maximum length [m]
Wire cross-section [mm²]	Node = 32	Node = 64	Node = 100
0.25	200	170	150
0.5	360	310	270
0.75	550	470	410

Example:
If user use Baudrate 100 kbit/s and wire cross-section 0.5 mm2, the maximum length can arrive to 500 m. But the maximum length is in inverse proportion to the node number. When the node number is up to 32, the maximum length will down to 360 m.
