Or the serial communication network of real-time control.For the dcs constructed compared with many RS-485 based on R line, it is based on
The dcs of CAN bus has apparent superiority in the following areas:
Data communication strong real-time between each node of network:
Firstly, CAN controller works in various ways, each node in network (can all take according to bus access priority
Certainly in message identifier) it is competed by the way of the bit-by-bit arbitration of lossless structure to bus transmission data, and CAN protocol is abolished
Station address coding, and instead communication data is encoded, this can make different nodes while receive identical data, this
The data communication strong real-time between each node of network that a little features constitute CAN bus, and be easy to constitute redundancy structure,
The flexibility of the reliability and system of raising system.
Development cycle is short:
CAN bus passes through the two output end CANH and CANL and physical bus phase of CAN transceiver interface chip 82C250
Connect, and the state at the end CANH can only be high level or suspended state, the end CANL can only be low level or suspended state.This is ensured that
The phenomenon in RS-485 network will not appeared in, i.e., when system is wrong, multinode occurs while sending data to bus,
Cause bus that short circuit is presented, thus the phenomenon that damaging certain nodes.And CAN node has automatically under wrong serious situation
Output function is closed, so that the operation of other nodes is unaffected in bus, so that guaranteeing is not in as in a network, because a
Other node goes wrong, so that bus is in " deadlock " state.Moreover, the perfect communication protocol that CAN has can be controlled by CAN
Device chip and its interface chip realize that substantially reduce system development difficulty, shorten the development cycle, these are only electric
The RS-485 of gas agreement is incomparable.
Form the fieldbus of international standard:
