Hi,

I had linked ThingWorx to KepServerEx and would like to display the value on screen.

I am using the GetProperties service and check "Automatically update value when able" checkbox

but I got error

if I uncheck the ""Automatically update value when able" checkbox, I got value showing on screen but not changing.

any reason why?

thank you

Can you check the application log to see if there are any more detailed errors?

Greetings!

I have never used the “Automatically update..." checkbox, but it is possible to add an Auto Refresh widget to the Mashup and use it as an Event Trigger for GetProperties. Auto Refresh has an adjustable refresh interval and a property that allows controls to be hidden.

Another way would be to use the ServiceInvokeCompleted event on GetProperties, but I suspect doing so would introduce unnecessary load since the service will then run continuously.
