NetCube Web-IO-3


The NetCube® Web-IO-3 are intelligent device-servers for 8 digital inputs and 8 digital outputs and for two serial ports. They acquire, process and save instruments and machines data and transmit them immediately or time delayed to a SQL-databank or a remote client. With the NetCube® Web-IO-3 up to 8 machine inputs and outputs 24 VDC and two RS232/485 devices, such as PLC, barcode readers, scales, etc. can be connected to a TCP/IP network or a Modem simultaneously.

Thanks to their powerful X86-300 MHz running under Linux™, 128 MB RAM and up to 4 GB flash memory the Net-Cube® Web-IO-3reach unprecedented performances for such a little size.

Their opto-coupled I/O and 24VDC power supply, both protected against inverse polarity, as well as the DIN-rail make them particularly well suited for rugged industrial applications.

Embeded Software

Standard embeded Web applications include:

  • the configuration interface ”Easy Set-Up”.
  • Sigma, a revolutionary application generator which allows to program automation tasks and data processing in the same environment. With Sigma you create any application ”zero-code”, i.e. without compiler or libraries, hence eliminating the need for programming languages or cumbersome debugging.

Application examples

Typical applications examples include:

  • Transfer of machines data into SQL databanks.
  • Intelligent client for bare-code readers
  • Integration of machines and equipment into MES (Manufacturing Information System).
  • Data acquisition, analysis and back-ups in real-time for the traceability of production
  • Automatic alarm messaging via E-mail
  • Firmware updates and remote maintenance via Internet or Modem
