Error 200282 Measurement Studio 2015 (VS 2013) Reference Trigger

[TrentNene]

Hello,

I'm very new to measurement studio but have an existing licence for Measurement Studio 2015.

I'm using a cDAQ-9171 with a 9775 module.

I am programming in C# trying to set up an analogue reference trigger, however I get the error: 200282.

I have configured the reference trigger:

myTask.Triggers.ReferenceTrigger.ConfigureAnalogEdgeTrigger("cDAQ1Mod1/ai0", AnalogEdgeReferenceTriggerSlope.Rising, 1, 100);

I have tried different "ReadRelativeTo." but always get an error.

Thank you!
