Touch screen panel for plotting

[Keith1976]

Hi All;

Does anyone have experience with Honeywell HC900+HCI touch screen?

Can I plot historical value of an AI on HCI touch screen?

Thanks,
Keith

Yes, H-W Operator interface can display trend screens in one of 2 modes.

Note: Trending is not associated with data stored on the floppy or ZIP drive.
Data stored on floppy or ZIP can only be viewed with PC software, not on the O/I.

Mode 1 - Single loop faceplate with loop trend screen,
Operator Interface User Guide 51-52-25-108; pg 142 (pdf)

http://hpsweb.honeywell.com/Culture.../hybrid/HC900Interfaces/Manuals/documents.htm

If memory serves me, this is a 15 or 30 minute trend screen for which there is no cache memory, the implication being, that if the operator changes the screen to something else and comes back to the trend screen, the trend screen starts over again, there is no residual trend from the previous screen. The trend starts every time the screen is accessed. There is no scroll back, so the visible time domain is a moving 30 minute window: from NOW to 30 minutes ago. The intention was to use it for tuning a loop.

These screens are not 'configured', screens become available when a loop is implemented.

Mode 2 - Monitoring historical trends
samples and descriptions of the various trend screens are described in the Operator Interface User Guide 51-52-25-108, starting on page 281 (pdf)

Trends data is saved in memory (not the floppy or ZIP drive) so that whenever any screen is accessed it populates with historical data.

These display screens need to be configured (activated and populated) in the development software, Hybrid Control Designer (HCD). The HCD manual is 51-52-25-10

Danw2,

I am referring to touchscreen model HCI. Can I use it to display the data from previous 8 hours? Sampling rate 5 minutes.

Thanks and regards,

I can't buy a 'production' model touchscreen model in the US.

There have been rumors of a touchscreen as a replacement for the 559/104x O/I's for several years now, but with Honeywell, it isn't 'real' until it hits the street.

If you're in the US and you actually have a touchscreen unit, it must be an Alpha or a Beta model and you'll have to ask the guy who provided it for answers.

I'd like to see it; can you take a photo and post it?

Dan;

Attached is the sales brochure. By the way, I am in Singapore, Asia.

Very interesting, the brochure is dated 2007, so it's been out for awhile now.

It appears that the panel's development software, HCi, runs right on the panel itself, as opposed development on a PC and 'downloading' a config program.

The sales brochure doesn't say anything about the multitude of pre-developed screens the 559/1042 units use, this unit appears to be all custom developed screens.

Thanks for sending it. Dan
