Why Disable a Channel on a Honeywell Paperless Recorder?

Written by: Dan Weise

Over time, changes in your process needs occur, and a sensor you’ve connected to a Honeywell paperless recorder channel may be taken out of service. When this happens, I suggest that both the analog input and the pen be disabled. Here’s why:

Changing the Clock Battery on a Honeywell Paperless Recorder

Written by: Dan Weise

The installed base of Honeywell Trendview X series paperless recorders is approaching an in-service period of a decade (introduced mid-2006). Given that kind of service time, you need to be aware of the issues involved in changing the clock battery.

The replaceable clock battery serves as a backup for the on board real-time clock chip as well as the internal battery-backed static RAM. If your paperless recorder is getting old, the battery may ready for a swap-out. If so, you may need a one-day-use access code that only Honeywell can provide, so plan ahead. You don’t want to get locked out of your recorder!

Marking Charts on Honeywell Paperless Process Recorders

Back in the day of paper charts, it was simple to mark a recorder chart – the operator pulled a pen out of his pocket and wrote on the chart, or the quality person rubber-stamped the chart.

Even with “paperless” charts on Honeywell’s Trendview, X-Series and G-Series digital recorders, it’s still easy to annotate.

Troubleshooting FTP failures on Honeywell paperless process recorders

One of the great things about Honeywell Trendview X-Series paperless recorders is that they communication via Ethernet. It’s great, because you can get data from your recorder anywhere on your plant network. But, since they’re network devices, you now have to understand how to troubleshoot network failures, and not just fix “regular” recorder issues.

Trendview recorders frequently connect to a local area network (LAN), so the recorded data can be easily transferred to the historian database portion of the recorder’s Trendserver Pro software (TSP).  TrendServer pro uses a standard Internet file transfer protocol (FTP) to grab data from the recorder. And in a lot of cases, a software scheduler is used to grab data on a periodic basis.

So, you’re cranking along, and the recorder’s talking perfectly to the server, and then one day you see one of the dreaded FTP failure messages.

So now, what do you do to diagnose and solve the problem?
