Which file do I pick for updating firmware with Honeywell’s SAT tool?
Posted by danstips in Honeywell, Level Technology, Service, Software, Troubleshooting on July 3, 2017
Last week, I was doing a firmware update on the Honeywell SLG700 guided wave radar using Honeywell’s Smart Anytime Tool (SAT).
Honeywell’s SAT firmware update tool needs to be “pointed” to the component type (sensor/display/communications module), and then the specific file needed for update. A recent release (R102.1) for the SLG700 listed two different files for the Advanced Display, but it wasn’t clear which file I needed to use. Read the rest of this entry »
Honeywell smart transmitter design makes communication card swap easy

It was bound to happen sooner or later.
I took a call from a customer who needed to replace a garden variety differential pressure transmitter… with one exception: He needed Honeywell’s DE digital protocol for communicating to his DCS. The DE protocol is still great, but since so many installations today use HART or Foundation Fieldbus, all of our in-stock pressure transmitters had a HART communication card – a critical mismatch to what the customer needed.
A year ago, we would have been stuck rush-ordering a unit from the factory, with all the attendant delays and expediting charges, because you couldn’t swap out a comms card without making the transmitter’s hazardous approval invalid.
What could we do?

HART communications without busting the budget
Posted by danstips in Communications, Configuration, Cost Issues, HART, Level Technology, Service, Siemens, Software, Transmitters on March 15, 2013
The HART communication protocol has been firmly established as the standard means of configuring field instruments for some years. But talking to a field instrument needs a communicator.
There are the handheld communicators, Rosemount’s x75s and the “budget-priced” Meriam MFC 4150, but at a cost that’s more a capital appropriation than an MRO expense. Even the Meriam, with a 3-year field device description subscription starts at more than $4000.
People continue to ask me if there isn’t a more budget conscious approach to HART configuration.
