Hello All, Thank you for your comments. i'm going to try and answer questions as best i can: the sensor i will be using is an Edwards Vacuum APG200M which i believe has an operating range of 1.8-9.2V , from previous experience calibrating these i believe this will have to be a linear performance curve. Joe: nothing as fancy as deep vacuum , this will be from atmospheric to rough/medium vacuum with a range of ATM to about 5x10-4mbar i agree with changing from fast to normal mode to get more resolution and the speed different will be negligible. thank you for your explanation for the thought process , this has so far been the most daunting aspect this so far ausman: you are correct in your reply about it being as just a reading of 6.8 - 03 etc. flex727: hopefully this is a good habit i will be able to pick up from the more experienced gents and ladies on here as there is a great deal of knowledge available on this forum and everyone has been very helpful so far! thank you all for your time!

Good Morning Dan, thanks for your explanation on this, unfortunately my hands are tied in terms of using scientific notation for vacuum measurements on this project. BenC

Morning thank you! , apologies i read the DO's and DON'TS after i had posted this. i am using a V1040-T20B with an IO-AI8 for the analogue input in question. is there any more information you need?

Hello all. I've recently started using Visilogic PLC's and Unitronics equipment as a complete novice with no more than "some" common sense and a bit of background computer knowledge. So far I have managed to complete simple tasks (HMI , jumps , buttons , basic linearization, HW config) on the project I am currently working on, however I am having some issues with some more advanced functions, in particular logic functions and some maths functions. i have a 0-10v vacuum transducer which is set in the hardware configurator as a 10-bit(fast) analogue input, i would like to make this to read in scientific notation such as X.XXe^X Mbar values is there a recommended way to try and approach this or is there a function block similar to the linearization FB i can use? any help or guidance on this would be greatly appreciated many thanks, Ben
