Siemens Logo 0BA8 and Weintek 8071iE trend display problem

[mobisat]

Afternoon all,

I have a Weintek 8071ie HMI that I am using to interrogate 5 off Siemens Logo 0BA8 as a plant temperature monitor and alarm system over my LAN. The problem I have is with recording my temperatures with a data sampling object, a trend display and history.

I can read and display my temperatures from AM1 and AM2 using numeric display objects by reading AM1 either directly or VW0 or VW1118 and AM2 either directly or VW2 or VW1120 so this proves that the information can be read on these addresses.

However I have tried all these addresses in the data sampling object and tried to display them in a Trend display and also history and nothing is displayed.


Hopefully this makes sense and someone can advise where I may be going wrong.
