Features
LP-8781 equips a LX800 CPU (500MHz) running a Linux 2.6.18 Operating System, variant connectivity (VGA, USB, Ethernet, RS-232/485) and 7 slots for high performance parallel I/O modules (high profile I-8K series) and serial-type I/O modules (high profile I-87K I/O modules).
Programs can be saved in an external storage device, such as a CF Card, USB device or RAM via ethernet. A LinPAC SDK is provided for help with developing LinPAC I/O applications rapidly and easily when I-7000 / I-8000 / I-87K series I/O modules are used in the LinPAC. Users can develop LinPAC applications by using GNU C Language. In the meanwhile, all kinds of servers and functions built-in make the LinPAC more powerful and users will be able to operate LinPAC to achieve their own project smoothly. With LP-8x81 series, users can achieve the redundancy function and it will make the whole control system safer.
- Development Environment
- LinPAC SDK : ICP DAS provides the library file - libi8k.a which includes all the functions of the I-7000/8000/87k series modules. Users can develop LinPAC-8x81 Applications easily by GNU C Language.
- Built-in Server
- Web Server : Through these servers, users active web pages can be placed in the LinPAC and make LinPAC be a Web Site. Telnet Server, SSH Server: Through these servers, users can remote control and transfer files with LinPAC by encrypting mode.
- Security
- Unique Serial Number: As soon as “Unique Serial Number” added in users’ program, then users’ program will be locked for this LinPAC.
- Interpreter
- Perl, PHP : The program written by Perl and PHP interpret language can be also executed in the LinPAC.
- GUI
- GTK+ Library, Users can write LinPAC GUI programs by using GTK+ library.
- Other:
- Dual Watchdog Timer, Built-In Flash Disk (4GB). Dual Battery-Backup SRAM (512KB), There are one resolution mode supported in the LinPAC.
