RapidData binding problem

charon

Hi,

i try to change text property of a TpsLabel by binding it to a controller object. I create persistent string datas as described in video tutorials. ScreenMaker build project and deploys it to VC with no problem but my application cant read any rapid variable from VC.

I have no problem with reading signal values from VC. I add a LED object to project and bind it to  controller signal source(MOTLMB sys signal) and it works and refresh its value normally.

i use RobotStudio 5.13.02 on XP SP3 PC

Hello,

Do you get any error message box in Virtual FlexPendant on opening the application ?

What is your system language and OS settings (English or Turkish or anyother) ?

 

Thanks

i dont get any error messages when i run my application on VC.
My system language is English.(only my input language is set to TR keybord) By the way i try to add a DataEditor to my application and connect it to a Controller num data (persistent) but when i click to object it throws an exception like in the screenshot.

Hello,

 

Try it on a system with the input language also as English. And then launch VirtualFlexPendant.

This may be language specific issue.

 

Thanks
