java - 如何使用 bacnet4j API 连接 Scada BACnet 设备模拟器？

Question

我使用在本地主机上运行的 Scada Bacnet 设备模拟器创建了两个设备。命名为设备 0 和设备 1。我有 bacnet4j 测试代码，也在 localhost 中运行。我正在尝试获取这些设备对象的属性。但我收到以下错误。

线程“主”com.serotonin.bacnet4j.exception.BACnetTimeoutException 中的异常：在 com.serotonin.bacnet4j.transport.Transport.sendSegments(Transport.java:273) 等待 com.serotonin.bacnet4j.transport.Transport.sendSegments(Transport.java:273) 的 id 0 响应时超时。 transport.Transport.send(Transport.java:188) 在 com.serotonin.bacnet4j.LocalDevice.send(LocalDevice.java:376) 在 Test2.getObjectList(Test2.java:63) 在 Test2.main(Test2.java:52 )
