gongue Posted August 29, 2010 Report Share Posted August 29, 2010 Hi all. My project V570, I have a flow instrument (FIT) with 4-20mA output. this instrument internally makes totaled in m3, need to show this information (totaled) of the instrument in the HMI is achieved only by HART obtain.<BR style="BACKGROUND-COLOR: #fff">visilogic anyone know if you do it? or that otherwise do? thank you in advance for any help.

Hello, Unitronics don't support HART on their analogue inputs. However you could use an external device on ethernet, for example. The Turck BL20-E-GW-EN ethernet gateway with BL20-2AIH-I analogue HART input module should allow you to read the HART registers via ModbusTCP. I have one on my desk to play with, haven't got there yet, but will try to post the results once I do. Quote Link to comment Share on other sites More sharing options...
Emil Posted August 30, 2010 Report Share Posted August 30, 2010 Maybe, reading analog signal 4-20mA,which reperesents the flow, you can calculate the total. V570 has very powerful, practically unlimited math functions! Quote Link to comment Share on other sites More sharing options...

V570 has very powerful, practically unlimited math functions! This is the cheap way. I done this a couple of times with vortex flowmeters.
