Is there that difference between a Rosemount 275 or 375 and ABB's 491. I have a 491 that cannot be connected
Reply #22009-11-21
Is ABB's 491 a HART protocol? The software versions are not compatible. If the protocols are different, they cannot be used universally. If it is just a software problem, it may be enough to download the relevant software.
