1 Port Programmable DeviceNet Interface
I-87124
Introduction
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.
It is popularly applied in the industrial automation, building automation,vehicle, marine, and embedded control
network. In order to expand the DeviceNet functions of ICPDAS products, i-87124 module is developed for this
purpose.
