FOCUS TECHNOLOGY
Distributed Control Networking
-
CAN (Controller Area Network)
eCANBase
-TypeIII
- CAN controller is a standard communication protocol designed for micro controller(ECU) or devices can be connected to each other without hosting computer inside of automotive.
- CAN controller is not only for automotive cars but also industrial automation devices and medical devices.
-
[Economical Composition]
CAN Data BUS system uses two lines for transmitting data, therefore it can reduce wiring cost.
-
[Multi-Master]
CAN Data BUS system can communicate as master controller unless the progress of transmitting/receiving messages on bus line.
-
[Strong Safety]
CAN Data BUS is two twisted communication lines which is durable to noises. It is possible to detect the errors of communicational data through the function of detecting errors, so when an error occurs, it can transmit data again immediately
-
[Messaging Method]
CAN Data with messaging ID method is able to implement multi-drop communication deciding whether receiving data based on message ID at receiver controller.

CAN-FD (CAN with Flexible Data Rate)
eCANFDBase
-TypeII
- CAN-FD Communication is a new communication standard to implement communication by changing data transmitting speed to increase loading data of CAN communication which is standard communication protocol inside of automotive and for short waiting time with the purpose of fast movement.
- CAN-FD communication has up to 8 times as much data space and 8 times more data transfer speed than CAN communication.
-
[High-speed Transmission
CAN-FD is able to transmit data faster with the speed of 8Mbps maximum.
-
[Large Data Volumes]
CAN-FD is a data space which can be expanded up to 64 bytes, allowing transmit large data at one time.
-
[Strong Compatibility]
CAN-FD supports compatibility to standard communication protocol CAN 2.0A, CAN 2.0B.
-
[Safety]
CAN-FD ensures safety by keeping the data rate for checking and maintaining the data transmission / reception state of the bus the same as that of the conventional CAN 2.0.

SENT (Single Edge Nibble Transmission)
eSNTBase
-TypeIII
- SENT communication is a standard of unidirectional protocol designed to receive input data of high resolution sensor data inside of car through digital communication.
- SENT ensures data security through error detection function.
-
[Simple Composition]
Sensor with SENT is received two power supply lines from ECU and consists of one SENT line for communication.
-
[Stable Data]
SENT can perform stable data transmitting by sending sensory data changed from analog data to digital format from sensor.
-
[Error Detection]
SENT secures the soundness of data by adding error detection function of communicational data.
-
[High Resolution]
LIN communication is able to detect error from all data in message frame by using inverter modular 256 checksums. This communication is able to examine the soundness of node by overseeing slave nodes from master node

LIN (Local Interconnect Network)
eLINBase
-TypeIII
- LIN communication is mainly used on the communication between automotive ECU and active sensors / actuators.
- LIN communication consisted of one master(ECU) and multiple slaves (sensors and actuators) and has the maximum communication speed of 20Kbps.
-
[Simple Master]
LIN Communication is initialized and transmit all messages by single master on networking system.
-
[Flexible Data]
LIN communication can vary the number of data by the length bits of message field of the identifier field.
-
[Multicast reception]
LIN communication can read messages from any node connected to the network when the message is sent.
-
[Error Detection]
LIN communication is able to detect error from all data in message frame by using inverter modular 256 checksums. This communication is able to examine the soundness of node by overseeing slave nodes from master node
