Brochure covers redundant fieldbus
system
The Trunksafe brochure explains how, with Trunksafe, it is not necessary to duplicate the entire segment to achieve redundancy.
MooreHawke has released the Trunksafe brochure, which contains technical details on the world's only redundant fieldbus system Previously, to obtain a fault-tolerant, redundant Foundation fieldbus system, users had to duplicate everything in the segment, including H1 cards, power supplies, device couplers and all the field devices, such as transmitters and valves

Moore Industries' WLM employs frequency hopping spread spectrum technology and 32-bit CRC error correction for secure, robust communications.
Achieving redundancy was extremely expensive and relied on special software within the DCS.
If a critical process unit goes down because of a failed fieldbus segment, the cost can be enormous: some estimates say US $500,000 per hour when a refinery is down.
The fieldbus world has needed a fault-tolerant system for years, but few redundant systems have ever been installed in the process control industry because of high costs and systems configuration headaches.
The Trunksafe brochure explains how, with Trunksafe, it is not necessary to duplicate the entire segment to achieve redundancy.
Most important, it is not necessary to duplicate the field instruments nor to have any special software at the DCS, which can save users tens of thousands of dollars per fieldbus segment.
