The CAN (Controller Area Network) is a serial
communication protocol, and efficiently supports distributed real-time
control with a very high level of security. It is an especially suit
for networking "intelligent" devices as well as sensors and actuators
within a system or sub-system. In CAN network, there is no addressing
of subscribers or stations in the conventional sense, but instead
prioritized messages are transmitted. As standalone CAN controller,
I-87124 can represent an economic solution of DeviceNet application
and be a DeviceNet master device in the CAN bus on the DeviceNet
network. It is a "Predefined Master connection Set", and supports
Group 2 only Server functions to communication with slave devices.
It has a independent CAN bus communication port with 5-pin screw
terminal connector, and has the ability to cover a wide range of DeviceNet
applications. Besides, I-87124 uses the new CAN controller Phillips
SJA1000T and transceiver 82C250/251, which provide bus arbitration,
error detection with auto correction and re-transmission function.
It can be installed in I-8000 or WinCon-8000 series PAC. |
