Giới thiệu bộ lập trình nhúng Linux PAC -LP-9000 hãng ICP DAS

Nowadays, Linux has been adopted widely by many users because of the properties of stability, open source, and free of charge. In the mean while, owing to the great supports from more and more companies and the mature development, Linux is now becoming one of the most popular OS on the market. 

The LinPAC-9000 is new generation Linux-based PAC from ICP DAS and is equipped with a powerful CPU module running a Linux kernel 3.x operating system, various communication interfaces (VGA, USB, Ethernet and RS-232/485) and slots for both high performance parallel bus type (high profile I-9K series) and serial bus type (high profile I-97K series) I/O modules.

Compared with the first generation LinPAC-9000, not only is the CPU performance improved have been added (1.0 GHz) and support Linux kernel 3.x, but many reliability features, such as dual LAN, redundant power input, and dual battery backup SRAM, etc., making the LinPAC-9000 one of the most powerful systems available.

Software Features

• Remote Maintenance via SFTP/FTP Server and SSH/Telnet Software

The SFTP/FTP server is used for uploading applications or downloading data. And SSH/Telnet is designed for managing the LinPAC-9000. By using the FTP server and SSH/Telnet, you can update and manage the LP-9000 remotely via the Ethernet.

• Rich Software Solutions

ICP DAS provides the library file － libi8k.a which includes all the functions of the I-7000/9000/97k series modules. Users just install LinPAC SDK in Windows PC, the cygwin environment will be established automatically and users can develop LinPAC-9000 applications easily by GNU C Language. Apart from that, users can also use Java to develop LinPAC applications as well.

Note: Cygwin is a Linux-like environment for Windows.

Hardware Features

• Powerful CPU Module

LP-9x2x is equipped with a Cortex-A8 (1.0 GHz) CPU running a Linux operating system.

• Built-in VGA Port

A built-in VGA port can be directly connected to a regular LCD display. Users can operate the HMI or SCADA software (running on the LinPAC-9000) with display, keyboard and mouse just as how they usually did on regular PCs.

• 64-bit Hardware Serial Number

The 64-bit hardware serial number is unique and individual. Every serial number of LinPAC-9000 is different. Users can add a checking mechanism to their AP to prevent software from pirating.

• Rich I/O Expansion Ability (RS-232/485, Ethernet, FRnet, CAN)

Beside the local I/O slots, LinPAC-9000 also equips several RS-232/485 ports, two Ethernet ports to connect serial I/O and Ethernet I/O. And with FRnet and CAN communication module in local slot, FRnet I/O and CAN devices are easy to be integrated.

• Dual Watchdog Timer

A system could be hanged up when the OS or the AP fails. There are two watchdogs (OS watchdog and AP watchdog) designed to automatically reset the CPU when the situations happen. The design will increase the reliability of the system.

• Dual Ethernet Ports

LinPAC-9000 provides two Ethernet ports. The two Ethernet ports can be used to implement redundant Ethernet communication and separate Ethernet communication (one for global Internet, one for private Ethernet).

• Rugged RJ-45 connector for LAN1

The LP-9000 is equipped with a rugged and dustproof RJ-45 connector on the LAN1 port that is able to provide protection against both liquid and dust contaminants in harsh industrial environments, as well as protection against vibration and shock.
