I am trying to use system.opc.readValue and check the quality. Here is a snippet of sample code:
qualifiedValue = system.opc.readValue('IgnitionOPCUA', opcPath)
if( qualifiedValue.quality.isGood() ):
# quality is good, can continue
print qualifiedValue.value
else:
# quality is bad, need to do something else.
In essence, I want to check to make sure that the opc read succeeded before I work with the data. However, when running the above code, I get the following error:
Am I using this attribute wrong? I was trying to use it the way the user manual specifies...
