How to read HART signal parameter using flex io 1794 IE8H in rslogix 5000?

[gspatil]

Dear all,

I have 1794 IE8H Hart flex input module to which one Emerson HART flowmeter is connected...I have gone manual of flex module...I have to write program to read 3 parameters from HART transmitter in RSlogix 5000 (compactlogics)....in manual there are so many & geeting confused how to get this...even got sample code from rockwell site...but still nt working...If anyone have any proper document to follow please suggest or mail me on [email protected]ks.

What is exactly the problem ??

I have a 1756-L75 controllogix plc connected over ethernet to a 1794-aent remote scanner. In this remote scanner rack, I have a 1794-IE8H (H for Hart). I am trying to MSG the 1794-aent to get the HART information but I cannot get the MSG instruction to work correctly. Connected to the 1794-IE8H is a rosemount level transmitter

Sis:
The HART Rebuild bit will trigger a HART Rebuild on a transition from 0 to 1. The
HART Rebuild bit must remain 1 for HART communications to function after the
rebuild completes. If the HART Rebuild bit is set to 0, HART communications are
disabled.
How to access it:
[Adapter Name]:[Slot]:C.Ch[Channel Number]HARTRebuild

sis:
You do not need any message to get HART data.
If you want please zip you acd file in order to review it.

I have simplified the program and only put what we are talking about in it. Take a look and let me know what you think.
Thanks,

It will not let me attach the file. I zipped it and it said that it is still too big
