1734sc-IF4CH Hart Enabled Analog Input Card

Hi all,

I am having a heck of a time trying to understand how to message to a HART enabled flow meter using the Spectrum Controls 4 Ch. Analog Input card.

Does anyone have any examples of this that they could send me? I am using a Control Logix with a 1734-AENT remote ethernet rack.

I am reading my PV, SV, and TV just fine from the Endress ProMag, but I want to send a command to clear the net totalizer. The Spectrum manual is a bit over my head when it comes to CIP messaging.

Thanks!

What is the model number of the Spectrum AI card ?

If possible post a link to the manual.


Oops yes I spotted it, lol

I think you will need to ask Endress & Hauser how to perform this function.

Or you could use the PLC to "tare" the totaliser by storing the current value, and subtracting it from subsequent values - that would give the effect of clearing the totaliser.

Ya, I gave Spectrum a call and they had no one that could help and directed me to Rockwell Tech. After calling Rockwell Tech....lol, the didn't even no what HART was. ROFL!!

I did call E+H today and they provided the attached.

It's too grainy to see, but did it help you ?

Thanks for that tidbit. I've had people ask me about alternatives to A-B HART enabled AI cards. Knowing that Spectrum makes a HART enabled AI card for which they can not provide any HART support is worth knowing and passing along.

....thought it would of added it as an attachment, not embed it.

But, no. It didn't.

It was the end of the day and I will be making a call again tomorrow.
