Weintek HMI and PLC Logo

1 post in this topic

Hi dear friends,

i'm working with a Siemens PLC LOGO 8 (OBA8) that connected to a Wientek HMI model MT7081IE via Network.

and my Problem:

i'm trying to get the PLC LOGO time for displaying and editing on the HMI panel, i know that the Time address in the plc logo8 is VM988 and VM989 and VM990 (Hour:Minute:Second) but in easy boilder when i selected an Numerical object there is only VD and VW variables available to select and there is not VM selection (Please see the attached picture). thats way i select VW pisition with the same position Number (for example VW988) for get the Hour value and it's displays a big binary number that contains Hour and minute value in binary, also i can find that witch characters are for hour value and witch one are for minutes value.

Please help me that how can i separates the characters and dispalys them into another numerical objects? or another ways to get time values from the OBA8 and displaying on the HMI.

 

Thanks and Regards

Saber
