Hi,
I have tried to subscribe to an OPC UA node - just took the few lines from the
subscription example - and I get following stack trace.
I hope someone can tell me what I am doing wrong… :-)
val builder: PlcSubscriptionRequest.Builder = plc!!.subscriptionRequestBuilder()
topics.forEach {
builder.addChangeOfStateField(it.payload, it.payload)
}
val request = builder.build()
val response = request.execute()
val subscribeResponse = response.get() ==> the exception is thrown here
