We had a full house last week here in Charlotte, as we played host to a large group from the Savannah River Site. The focus of the three days was Wireless HART (WiHART) networks, and we had extensive, hands-on sessions.
Security was a primary focus, both to make sure the WiHART networks didn’t interfere with other RF domains and to make sure the WiHART network was secure from outside interference, both accidental and intentional.
Another clever security feature is the ability to use a HART modem attached to AMS to automatically setup the join keys on the wireless devices. This way, knowledge of the join key is limited, and only instruments that get temporally connected before being deployed to the field can join the appropriate gateway.
Our guests came well prepared also, bringing a couple of guys in from Oak Ridge with all sorts of RF sniffing tools. They were specifically looking at our 4 wireless office networks and how the WiHART devices were showing up in the RF world.
After the 3 days, the visit was considered a success. Emerson’s WiHART passed the test and with apologies to UPS, Rosemount and RE Mason can ask “what can Blue do for you”?
