We keep a Honeywell XYR6000 field transmitter network setup at the Lesman offices for training, customer demonstrations, and site surveys. And part of my job is to keep the system in working order.
Honeywell releases incremental firmware updates when they need to fix a bug or add functionality to the systems. I’d downloaded both the 201.1 and 202.1 update files from the Honeywell website, but had procrastinated in doing the installation. (Never happens to you, right?)
When I got around to doing the updates today, I pulled out the wireless device manager (WDM) manual [1.8MB PDF]. and turned to section 6.2, page 131. It has about 10 pages of step-by-step instructions on the update/upgrade process.
But then, I found myself wishing for another of those “missing pages from the manual”. While it has all the steps, here’s what’s missing: A map that tells me how long the steps take.
This morning, I came across two articles I thought were worth sharing. They’re both about industrial networks, but from two entirely different angles.
The first article is written by a network engineer at a manufacturing plant. The gist of it is something we at Lesman talk about often with our customers: Buy what you need. In this case, he’s talking about Ethernet switches for light manufacturing and assembly operations, where a field-hardened industrial ethernet switch may be overkill (and out of your budget).
