Plant Services - October 2007 - (Page 56) PERFORMANCE Automation Safest Figure 3. Security can be enhanced with equipment using frequency-hopping spread-spectrum (FHSS) technology, such as this 900 MHz WLM wireless link module. Source: Moore Industries around the boiler building to produce a strong, repeatable signal. Again, a wireless link module radio, analog input module and Modbus interface module at the effluent station communicated through a Yagi antenna on an existing outdoor pole. To date, the control room wireless link module has been successfully transmitting clean RF Modbus RTU signals to the DCS for more than two years without a hiccup. Using a demo system to prove that a full-scale wireless system can work saves time and engineering. We’ve duct-taped antennas to the top of a building, stood on the roof pointing an antenna manually, and used Moore Industries’s demo kit indoors and outdoors, in chemical plants and steel mills. If you want to try it yourself, ask a wireless vendor to bring a demo rig to your plant. Seeing it work is far more reassuring than any engineering analysis that only says it might work.
