[Mi...] Posted January 20, 2020 Share Posted January 20, 2020 Can anyone help me with the origin of the "Qdb" code used in PiWeb? For instance: ${Qdb.Characteristic.2002(-1)} = name of the parent characteristic displayed ${Qdb.Measurement(6,-2)} = The batch of the penultimate measurement is displayed. Our PiWeb instructor (extremely knowledgeable in Calypso and PiWeb) stated that it was a "simple text language" that did not originate with Zeiss, but he couldn't remember the proper name. I've tried googling but the closest I get is .Net . (I've heard the term "simple answer" so many times my hair stands on end when I hear it now!) Thanks a bunch in advance! 😎 Link to comment https://qualityforum.zeiss.com/topic/16742-origin-of-qdb-code-used-in-piweb/ Share on other sites More sharing options...

[Ri...] Posted January 22, 2020 Share Posted January 22, 2020 Qdb is a command to Query the database .Characteristic tells it to look in the Characteristic Table in the database. 2002 is the attribute key to return, like Characteristic Name -1 is the most recent value. So, in words, query the database and return characteristic attribute 2002's most recent value.
