takraj opened a new issue, #1102:
URL: https://github.com/apache/plc4x/issues/1102
### What happened?
The documentation says that tags added via `addCyclicField(...)` will be
polled in the specified time intervals. My expectation is to get subscription
events each time these fields are getting polled, but apparently I don't get
any. The other two types of subscriptions are working OK, however I don't see
any difference between `addChangeOfStateField(...)` and `addEventField(...)`
with the OPC-UA driver.
Example code to reproduce the issue:
```
PlcDriverManager driverManager = new PlcDriverManager();
try (PlcConnection opcuaConnection =
driverManager.getConnection("opcua:tcp://opcuaserver.com:48010")) {
PlcSubscriptionRequest request =
opcuaConnection.subscriptionRequestBuilder()
.addCyclicField(
"Demo",
"ns=2;s=Demo.Static.Scalar.String",
Duration.ofSeconds(1)
)
.build();
PlcSubscriptionResponse response = request.execute().get();
if (response.getResponseCode("Demo") != PlcResponseCode.OK) {
throw new RuntimeException("Not OK.");
}
AtomicLong counter = new AtomicLong();
response.getSubscriptionHandle("Demo").register(
subscriptionEvent -> {
counter.incrementAndGet();
System.out.println(subscriptionEvent);
}
);
Thread.sleep(10 * 1000); // 10 seconds
if (counter.get() == 0) {
throw new RuntimeException("No events received.");
}
}
System.out.println("OK");
```
