It’s surprising to me how many Honeywell Trendview recorders are used primarily for alarming. People tell us that they like the alarm screens on the old-style annunciation panels. On a digital recorder, they look like this:
Users say “It’s easy to tell at a glance, which points are in alarm because the red really stands out. And the process values show up right there under the tag. Everything we need is in one place”
When their Remote View option is turned on, Trendview paperless recorders display recorder screens in Internet Explorer as shown here:
Getting a printout was not as easy as using file > print, because the technology uses Active-X components in Windows, so the result is a blank screen; something to do with Active X and printing.
The two most common questions I get about paperless recorders are:
- How far back in time can I scroll back or playback the chart?
- How many days/weeks/months of data does the recorder save?
What people don’t realize is that the answers to these questions vary according to how the recorder’s memory is allocated.
To help you understand how the recorder’s memory works, let me explain how data is viewed and saved on a paperless recorder.
A customer contacted me earlier today after reading another blog post about running Honeywell TrendManager software on a Windows 7 computer. She was looking for a copy of the latest software compatible with her recorders and operating system. But because Honeywell is a large company with several different divisions and websites, it can sometimes be difficult for customers to find the downloads they need.
So here’s the quick fix:
Recently, a customer and I were talking about his Honeywell X-series paperless recorder, and how the information was appearing in TrendManager PC software.
The graphs were showing data with the original pen scales, 0° to 500° F. But the recorder rarely, if ever, read below 100° or above 400°, so there was a lot of “white space” on the trend chart.
Could we do anything about it?
One of the strengths of Honeywell’s X-series paperless recorders is password security. You can configure it to keep operators from making configuration changes, and it’s a necessary part of being able to view a recorder’s data using a web browser.
One of the weaknesses of Honeywell’s X-series paperless recorders is password security. And by that, I don’t mean it’s bad. I just mean it can cause problems if a user fails to enter their username and password right, and ends up locked out of the recorder.
So I’m guessing if you searched for the backdoor password, you’re in that situation. You’re locked out of your recorder and can’t figure out how to get back in.
First, I apologize for luring you into reading this. There is NO backdoor password for an X-series recorder. But don’t give up hope: There is an answer.
(What’s a back door? Watch and learn.)
Hopefully, there’s a user at your location with administrator level access, who can reset a locked-out user. But if that’s not the case, what do you do when everyone is locked out of an X-series recorder?
