A task force has been set up to establish an EN fieldbus standard under the IEC (17B) for actuators and sensor devices.
This will provide a further route for buses to be accepted on public utilities over ECU200,000, currently covered by EN 50170.
A proposal recomending the AS-Interface bus was originally leading, but this was challenged by representatives from the Open DeviceNet Vendors Association (ODVA), Echelon (LonWorks), Honeywell (SDS) and Square D (Seriplex) at a recent BSI meeting. They argued that a more generic standard was appropriate for IEC 17B.
* A further high speed bus EN, led by InterBus-S, is also being considered with other suppliers.
* Bill Moss, executive director of ODVA, reports that membership of the DeviceNet organisation has now reached a full 200.
