Ethernet LAN CANopen Master: LAN controlled CANopen Master for DIN rail



  • Fully featured CANopen Master for up to 126 CANopen nodes
  • Open access via TCP/IP-based access protocol
  • Quick access via DLL with same API as PC fieldbus cards
  • Easy integration in embedded systems via 'C'-based driver source code
  • Open XML-based configuration possibility
  • Access to CANopen Slave object dictionary via SDO

Product Description

A netHOST FB is a full-featured and autonomously operating Fieldbus master allowing industrial PCs and other embedded systems the control of Fieldbus networks over an ordinary LAN connection.

A simple TCP/IP based transport protocol transfers the services between the controlling unit and the device. For device integration a DLL for Windows and a ‚C‘ source code for embedded solutions is provided. In both cases the call interface (API) is identical to Hilschers PC cards. This makes a netHOST a „remotely controllable PC card for field installations“.

100 bytes process data inputs and outputs are exchangeable over the LAN network in about one millisecond. Acyclic services to the subordinate Fieldbus stations are supported as well. A bus configuration software is included in the delivery.

Two devices can be used in combination to realize redundant applications. Services are provided to execute a controlled switchover in the event one device fails or a line breaks. In case a device fails the memory card slot allows service personnel to perform a firmware and configuration recovery on a replacement device in less than a minute.
