FF Field Device Testing and FF Technology Evaluation

The FF Starter Kit includes a complete set of hardware and software equipment that is required to set up and operate a FOUNDATION fieldbus (FF) H1 network. This tool is suited for learning how to use FF technology and represents the best starting point for instrument manufacturers planning to implement FF functionality in their field devices.

  • Easy Network Setup
  • Becoming Familiar with FOUNDATION fieldbus
  • Test Environment for Device Development


Easy Setup of FOUNDATION Fieldbus H1 Network

The FF Starter Kit includes all hardware and software components necessary to setup, configure, and monitor an FF H1 network. It is mainly based on Softing’s successful FF products and includes a Linking Device, a sample FF H1 field device with interactive simulation capabilities, a Windows-based configuration tool, a power conditioner, cables, as well as detailed documentation. This stand alone Starter Kit has been designed with ease-of-use in mind and does not require any development or other time-consuming preparation work.

Becoming Familiar with FOUNDATION Fieldbus

The plug-and-play FF Starter Kit allows evaluating and learning FF technology. Users of this solution are enabled to gain practical experience in planning, configuring, setting up, running and maintaining a network. In addition to learning purposes, the Starter Kit can be used for demonstrations and showroom applications. 

Test Environment for Device Development

The FF Starter Kit is moreover designed for laboratory and development use and enables users to carry out FF H1 field device tests. The included Linking Device provides access via FF High Speed Ethernet (HSE) to up to 4 segments with up to 16 devices each. Process values can be monitored and individual network situations can be tested by using the FF H1 field device simulation capabilities.
