Local I/O Slot:
There are 0/1/4/8 slot options to expand local I/O. And the I/O modules can be parallel bus type (high profile I-8K series) and serial bus type (high profile I-87K series). The difference between them is

RS-485:
The built-in RS-485 COM ports enable the communication baudrate up to 115.2 kbps. The medium for connection is a twisted-pair, multi-drop, 2-wire RS-485 network that can link I-7000, M-7000, RU-87Pn and high profile I-87K modules.

FRnet:
FRnet is an innovative industrial field bus. It uses twisted pair cable to be the transmission medium. Each FRnet port can link up to 128 DI and 128 DO channels. The whole I/O statuses are updated at a fixed cycle time (0.72 ms or 2.88 ms) no mater how many FRnet I/O modules is connected to the FRnet network. Further more, the update is done by hardware, there is no communication protocol is needed. Using FRnet, the user can easily and quickly implement high-speed distributed I/O control systems. Its key features are:
ˇ@
 
  • Easy connection: multi-drop networking with twisted pair cable
  • Easy programming: memory mapping (no communication protocol needed)
  • I/O expansion ability for each port: 8 SA nodes (for DI) and 8 RA nodes (for DO), each node addresses to 16 DI or DO channels.
  • Normally FRnet module provides two communication speeds. OEM customer can call maufacturer to design special FRnet module for long distance communication.

CAN Bus:
The Controller Area Network (CAN) is a serial communication way, which efficiently supports distributed real-time control with a very high level of security. It provides the error-processing mechanisms and concepts of message priority. These features can improve the network reliability and transmission efficiency. Furthermore, CAN supplies the multi-master capabilities, and is especially suited for networking ˇ§intelligentˇ¨ devices as well as sensors and actuators within a system or a sub-system. With I-8120, I-8123, I-8124, I-87120, I-87123, and I-87124, WinPAC-8000 is able to demonstrate every feature of CAN, CANopen, and DeviceNet.
