Giới thiệu bộ lập trình nhúng MiniOS7 PAC iP-8000/I-8000 hãng ICP DAS
The iPAC-8000 is a new family of compact, modular, intelligent and rugged, distributed I/O (input/output) systems, designed for data acquisition and control in manufacturing, research and education.
This new exciting series offers a flexible, versatile, and economical solution to a wide range of applications. From Data-Acquisition, process control, test and measurement, to energy and building management.
The iPAC-8000 is a modular network based system with the capability of connecting I/O either through it's own local bus or alternatively through I/O expansion or network extension.
The unit comprises a main control unit with a range of standard communication interfaces, and an I/O bus permitting I/O expansion. The bus is hybrid in nature providing the facility to connect either serial or parallel I/O modules. The parallel bus is used for high speed data transfer.
The unit can communicate either using serial communications (RS232,RS485), Ethernet, or CANbus.
The Ethernet version of the product supports an integrated web server permitting Internet and Intranet applications.
The unit can communicate either using serial communications (RS232,RS485), Ethernet, or CANbus.The iPAC-8000 can be used as an intelligent distributed data acquisition front end connected to a Host machine running a standard SCADA package, or alternatively it can be user programmed as an autonomous controller running an embedded software application. Significant non volatile memory is available for data and program storage.
Main Features
Main Control Unit (MCU)
The MCU is the power house of the iPAC-8000. Each MCU comprises a central processor module (CPM), a power supply, a four(4) or eight(8) slot backplane for either 4 or 8 Parallel I/O modules. The CPM is powerful integrated processing engine comprising a CPU, RAM and ROM, and an option of communication interfaces including RS-485, Ethernet and CANbus.
Embedded OS
All iPAC-8000 is equipped MiniOS7 embedded OS. It is developed by ICP DAS Co., ltd and compatible to DOS. MiniOS7 has more features than regular DOS in embedded applications, such as shorter boot time, built-in hardware diagnostic function, directly support I-8000 and I-7000 modules without library, and directly support Micro SD and Flash disk.
I/O Modules
There are two types of I/O communication bus, parallel bus and serial bus. The parallel bus type I/O modules (high profile I-8K series) are high speed ones.
Remote I/O Expansion
The iPAC-8000 uses built-in RS-485 and Ethernet ports to connect RS-485/Ethernet remote I/O units (Ru-87Pn/ET-87Pn) or modules (I-7000/M-7000/ET-7000). In this configuration, iPAC-8000 expands the I/O very easily. Using CAN communication module, iPAC-8000 can connect CAN bus devices, remote I/O units for deterministic control system.
Selection Guide
The controller is equipped with a DOS-like OS, called MiniOS7. Its software development toolkit is C language compilers that can build 16-bit executable file (*.exe) running on an 80188/80186 CPU, then download it to the controller.
The supported C/C++ compilers are TC++ 1.01、TC 2.01、BC++ 3.1 ~ 5.2x、MSC 6.0、MSVC++ (before version 1.5.2).

Remote I/O Expansion
Ethernet
The available Ethernet I/O devices are ET-7000, ET-7200, ET-87P4/8-MTCP and I-8KE4/8-MTCP. The PAC can access them in Modbus/TCP protocol. A nModbus.dll is provided for C#, VB.net programming.
RS-485
The PACs are equipped with the 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 with high profile I-87K modules. To access M-7000, a nModbus.dll is provided for C#, VB.net programming. To access I-7000 and RU-87Pn with high profile I-87K modules, PACSDK is provided for C#, VB.net, VC and VB programming.
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. With a FRnet communication module (I-8172W), the PAC can link FRnet I/O modules to implement high-speed distributed I/O (FR-2000 series). To access I-8172W, a pac_i8172w.dll is provided for C#, VB.net, VC and VB programming.
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-8123, I-8124, I-87120, the PAC is able to demonstrate every feature of CAN, CANopen, and DeviceNet.
