I-8120W-G CR: Module 1 cổng CAN Bus cho bộ lập trình điều khiển PAC


Common Features

  • Support WinPAC-8000, ViewPAC, XPAC-8000, XPAC-8000-CE6 series MCU (driver for LinPAC and iPAC will be Available Soon)
  • 8 KB DPRAM inside
  • RTC(Real Time Clock) inside
  • Allow user to program user-defined firmware in I-8120W
  • Support default firmware update
  • eVC++, VC6, VS 2005(VB.Net, C#.Net, VC++) demos and libraries are given
  • C/C++ function libraries of firmware and demos are given

Note: The XPAC-8000 series MCU can support only 1 I-8120W.

CAN Port Features

  • The XPAC-8000 series PAC can support only 1 I-8120W
  • Follow ISO11898-2 specification
  • Philip SJA1000T CAN controller
  • Philip 82C250 CAN transceiver
  • CAN controller frequency: 16 MHz
  • 2500 Vrms photo-isolation protection on CAN side
  • Switch for 120 Ω terminal resistor of CAN bus
  • Compatible with CAN specification 2.0 parts A and B
  • Provide default baud rate: 10 kbps, 20 kbps, 50 kbps, 125 kbps, 250 kbps, 500 kbps, 800 kbps, and 1 Mbps
  • Allow user-defined baud rate
  • Cyclic transmission precision: ±0.5ms precision when cyclic time is below 10ms , ±1% error when cyclic time exceeds 10ms
  • Provide 5 sets of cyclic transmission
  • Timestamp of CAN message with ±1ms precision

Note: We have verified to drive 100 CAN nodes at the same time via one CAN port of I-8120W.

Software Utility Features

  • Utility tool for downloading user-defined firmware and updating default firmware
  • Development Toolkit for eVC++ on WinPAC, VS 2005 (VB.Net, C#.Net, VC++) on XPAC-8000-CE6 and VC6 on XPAC-8000

  • I-8120W don't support any ISaGRAF series main control unit


The CAN (Controller Area Network) is a serial communication bus especially suited to interconnect smart devices to build smart systems or sub-system. It efficiently supports distributed real-time control with a very high level of security. In CAN networks, there is no addressing of subscribers or stations in the conventional sense, but instead prioritized messages are transmitted. As standalone CAN controller, I-8120W with WinPAC-8000/ViewPAC-2xWx/XPAC-8000/XPAC-8000-CE6 series MCU (main control unit) represents an economic solution. It has one CAN communication port with 5-pin screw terminal connector, and is useful for a wide range of CAN applications. Besides,I-8120W uses the new Phillips SJA1000T and transceiver 82C250, which provide both CAN 2.0A and 2.0B specific, re-transmission function, bus arbitration and error detection.
Combining the benefits of WinPAC-8000/ViewPAC-2xWx/XPAC-8000/XPAC-8000-CE6 series MCU without increasing the CPU loading heavily, it could be a powerful multi CAN port programmable device server by driving the program in the 186 CPU ofI-8120W. It can also communicate with other kinds of communication interface, such as RS-232/RS-485/Ethernet ports to be a programmable device server. Therefore, users can design the various applications between different communication protocols
