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 |

Ethernet:
The available Ethernet I/O devices are ET-6000, ET-7000, I-8KE4/8 and I-8KE4/8-MTCP. WinPAC-8000 can access them with Modbus/TCP or DCON protocol. |

RS-485:
WinPAC-8000 is equipped with two RS485 COM ports which enable the transmission rate up to a maximum of 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 that has many special features, such as high-speed deterministic I/O control, real I/O synchronization capabilities, non-protocol communication, and easy programming. Pluging in a FRnet communication module (I-8172W), the WinPAC-8000 can link FRnet I/O modules to implement high-speed distributed I/O. |

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 ¡§intelligent¡¨ 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. |
