Foundation fieldbus indicators can be nodes or listeners
21 April 2011
Beka associates' eight variable Foundation fieldbus indicators can now be configured on-site as nodes or listeners. As a node the indicator is configured via the fieldbus host, the instrument push buttons being used to select which pre-configured variable is displayed and, if required, to return operator acknowledgements to the host. As a fieldbus Listener the indicator is not visible to the host, does not use any valuable macrocycle time and may not be subject to a node licence fee.
All the models have an easy to read 20mm high 5 digit display plus a 31 segment bargraph. The range includes panel and field mounting ATEX, IECEx and FM certified intrinsically safe, Type n, nonincendive and safe area indicators.
Single variable Foundation fieldbus and Profibus PA indicators are also available.
