problème conversion data


Recommended Posts


Lors d'enregistrement de process nous rencontrons un problème.

Un enregistrement sur un temps très court et après conversion la pression affiche bien 33bar. Mais lors d'un enregistrement très long, la pression affiché n'est plus la même alors que les 33 bar sont bien présent.

Hello, During process recording we encounter a problem. A recording over a very short time and after conversion the pressure shows 33bar. But during a very long recording, the pressure displayed is no longer the same even though the 33 bar is indeed present.

math, a bit more information needed please.  What plc, what operands etc?  Is the 33 bar showing correctly at the plc using online mode or HMI?  You are saying that it is just recording that is showing the discrepancy?

cheers, Aus
