logix 5000 pulling info out of a rosemount

[Pickwick]

I have a logix 5000 with L75 processors and the Hart Analog modules 1756-IF8H/A, I have a Rosemount 3051SMV, this is a multivariable flow meter, my 4-20 output is a flow value, but I would also like to pull a second value out, Pressure. Since I have the HART module I am guessing that I could use a message block and read it from it but I am struggling with setting up the Service code, class, instance and attribute for this. I can t find any examples online. Has anybody ever done this? Is it possible to?

I believe on the 1756 modules there are 4 prebuilt variables already created in the object tree and polled for you
PV
SV
TV
FV

these can all be assigned on the transmitter side

page 5 shows you where to set it on your 3051SMV


looks like defaults might be as follows:

PV-Flow
SV-Delta P
TV- Absolute Pressure
FV-Temperature

I have done experimental stuff, re-ranging from hmi, etc..., with messaging before but will have to dig through my old notes because I never had to implement it, I think AB had a code snippet posted somewhere

I think this was part of it

Pickwick:
If you have a hart modem you can try to reconfigure your flowmeter if necessary:
You can download Prolink III Basic free from following page:
https://tools.emerson.com/OA_HTML/x...MMI=0001&section=10144&SP||EMR_PGOPTNS_IBE=01
Pactware is not the right tool to reconfigure a micromotion instrument.

I have a Micro Motion 2700
For the Prolink III do i need a licence for the sofware?
