Device from the NPE series is the industrial computer, equipped with the efficient
processor RISC ARM9 with preinstalled in the Flash memory operating system Linux
ver. 2.6. The computer is equipped with the Ethernet 10/100 BaseT port, two RS-232
ports, RS-485 port, 8 binary inputs and SD cards reader. The NPE computer cover
is especially adapted to the installation in difficult industrial conditions on
the DIN bus, and assures quick and comfortable installation in the target location.
The relatively small dimensions and the IP21 standard cover, no moving parts (fans,
discs) assure the failure-free operation in the industrial objects as well as in
various cabinets. Moreover, the NPE computer may be optionally produced in versions
with enhanced operational temperature range (-25°C¸ 70°C).

Customized versions for the individual needs
Currently, the automation, telecommunication and supervision systems require the
independent control or devices monitoring with the RS232 and RS-485 interfaces,
or equipped with the standard interfaces, like the binary or analogue inputs-outputs.
It becomes the real challenge, when it is necessary to use the autonomous solution,
which enables the independent work with the devices with serial ports without loading
the central computer. In such situations the industrial computer from the NPE series
is the perfect solution, which may independently perform most of activities, e.g.
change data through the serial ports, perform the data analysis in the real time,
buffer the collected information, communicate through IP, visualize the process
through the Web site and many other functions, according to the user’s needs.
The NPE computer has been equipped with the Linux operating system in version 2.6.
The programming method is almost identical as the software creation on the stationary
computer, and includes three stages:
Software Capabilities:
Java
PostgreSQL
SQLite3
Apache2
PHP5
Modbus
SNMP
Linux
Serwer E-Mail
1. Program creation on the stationary computer.
2. Program compilation with the cross-compiler (included on the CD C/C++ compiler,
enhanced with the libraries for the NPE input-output interfaces operation).
3. Copying of the compiled application to the FTP server, built in the NPE, or use
the NFS service in the Linux system.
Computers from the NPE family is the series of industrial built-in computers, characterized
by: complete, ready platform (hardware + installed Linux operating system + freeware
tools and programming libraries for C/C++), adapted to the operation in difficult
environment conditions (temperature range even form -20°C to 70°C) and high
operational reliability.
The NPE hardware configuration is based on ARM9 32-bit RISC CPU 180MHz processor,
64MB SDRAM, 1GB Flash disk. The NPE series computer has the real time clock and
SRAM memory, with the backup during the power supply failures, SD cards reader and
the Watch Dog Timer, protecting the computer against hanging. As the input-output
interfaces the computer has two RS-232 ports, RS-485 port and 8 binary inputs. The
NPE may be optionally equipped with more SDRAM, analog inputs or
1-wire (one wire) socket. According to the user’s requirements, and its producer,
TechBase company offers the possibility of ordering the dedicated versions, equipped
with non-standard interfaces and internal resources.
Offered model also have additional functionality:
