You can check input of e.g "un-scale" function and find the absolute address and monitor it in Variable table of use one of the following software mentioned here for archiving: Log internal variables of S7 CPUs There are some possiblities: 1-Tag archiving capability of WINCC 2-Autem PLC analyzer http://autem.de/index.php?site=en_home 3-ibaPDA-S7-Analyzer http://www.iba-ag.com/ Also check this: help with vat peripheral outpusts can not be monitored in a table but they can be modified. peripheral inputs can be monitored in a table but they can not be modified (Force).

However with a min/max of 0/1, I'm not sure what the output will be.
