Hello Rann Any Analogue value that you get from a PA Instrument is 4 Bytes longand you simple do a "L ID xyz" (if its address is in the Process Image) or"L PID xyz" (if its address is outside ofthe Process Image). There is no need for any "special" Blocks nor do you have to scale the value (its a Floating Point value already in Engineering Units). Note that any PA value also has a status byte associated with it (the fith byte) which provides inforrmation about the you quality of the value and which you would read seperately (e.g "L IB xyz" or "L PIB xyz"). I hope this helps |
