Recording Flow Readings at a City Water Plant

It's certainly a very straightforward thing to to - analogue input modules are easy to come by, and one of the A-B HMI panels could give you your graphical output.

But, unless you've got an SLC500 already there, with some spare capacity, and you know how to program it, this is going to be a very costly alternative to a dedicated chart recorder. For the cost of an A-B analog I/P module + graphical HMI, you could buy half-a-dozen chart recorders. Then you've got to program the PLC!

Thank you for your reply. I have the slc 500 already there. It controls our pumps and alarms.

If you already have an SLC500, you may be able to add an analogue in card like 1746-NI4. There are also alternative front-ends that might make it easier to log and display your data. Try searching for DAQFactory - I haven't tried it, but they seem to offer a lite version for low cost that may be suitable.

Good luck,

Need to know the required accuracy to determine the scan rate! If it's not too high then a data logger and an old laptop running Hydrocomsyswin would work. File size may blow out though, if fast scan rate!

I agree with JohnDG that unless you already have the AB gear, I'd look at another route. There are hundreds if not thousands of paperless data recorders out there, and they are more affordable than ever. Search for "paperless data recorders" and you will find them. Omega.com is a good place to start to get an overview of what's available to you. Campbell Scientific makes some rock solid products, Yokogawa and Astromed are among others you might look at. Let us know if you need more assistance.
Best Luck,

Yep! Here's another vote for Yokogawa (usual disclaimer), not Allen Bradley (usual disclaimer) on this occasion.

That link may work if you post it as a hyperlink (use the "Globe/Chain" icon to the right of abc at the top of the edit box) - but it doesn't work as it appears in your post.

Hello, I have used Honeywell trendview units in a company that does "fit for replacement

function" testing. The units are fairly easy to program and the units can be configured

to any number or type of input and outputs. Also they fit stander cutouts.

They can be configured with removable memory cards and floppy disks in addition to networking over lan.

Hope this helps. the units can be used as a stand a lone also.
