Hi everyone,

I would like to survey a cheaper solution in order to configure smart instruments using HART protocol. HART 275 Communicator is good for this purpose but too expensive, US$2500+. I have checked out http://www.hartcomm.org, http://www.thehartbook.com and http://www.romilly.co.uk, but I did not get any available solutions. I prefer the solution with "PDA + HART modem + software" or "Laptop + HART modem + software". The software should configure HART instruments from at least Rosemount, ABB, Yokogawa. The total price of HART modem & software should not exceed US$1200. I am appreciated with any helps. Thanks.

<P>We (Smar) make such a handheld based on the Palm platform. The HART interface for the Palm fits models III, V/Vx, m series, I series, and
Tungsten. See:

<P>We also make the laptop interface and software solution. See:

<P>My personal preference is the Palm solution because it is very compact and portable.

<P>These two solutions do not access 100% of functionality in all HART devices. However, all universal HART functions and most common practice functions are supported.

<P>The below list shows what HPC301, CONF401 or any HART master should be able to access in any HART slave provided it is supported in the instrument.
