volttron 故障排除 rpc 调用 get_point
volttron troubleshoot rpc call get_point
是否有机会获得有关如何对 BACnet 设备的简单 get_point rpc 调用进行故障排除的提示？我在 rpc 调用上做的事情抛出了这个错误：'DriverAgent\' object has no attribute \'interface\'
这是我的设备：
vctl config get platform.driver registry_configs/33333.csv
打印：
[
{
"Reference Point Name": "signal_payload",
"Volttron Point Name": "signal_payload",
"Units": "percent",
"Unit Details": "(default 0.0)",
"BACnet Object Type": "analogValue",
"Property": "presentValue",
"Writable": "FALSE",
"Index": "0",
"Write Priority": "",
"Notes": "Open ADR Payload Signal"
},
{
"Reference Point Name": "int_signal_duration",
"Volttron Point Name": "int_signal_duration",

"Unit Details": "(default 0.0)",
"BACnet Object Type": "analogValue",
"Property": "presentValue",
"Writable": "FALSE",
"Index": "1",
"Write Priority": "",
"Notes": "Integer Signal Duration"
}
]
设备地址：
vctl config get platform.driver devices/slipstream_internal/slipstream_hq/33333
这将打印：
{
"driver_config": {
"device_address": "10.200.200.224",
"device_id": 33333
},
"driver_type": "bacnet",
"registry_config": "config://registry_configs/33333.csv"
}
我认为我在 dr_level = self.vip.rpc.call 中的代理代码有问题，如下面的片段所示，因为代码在 ACTUATOR AGENT SCHEDULE SUCCESS 之后立即出错：
dr_status = self.vip.rpc.call(
'platform.actuator', 'request_new_schedule', self.agent_id, 'my_test', 'HIGH', schedule_bac0_request).get(
timeout=4)
_log.info(f'*** [Setter Agent INFO] *** - ACTUATOR AGENT SCHEDULE SUCCESS')
dr_level = self.vip.rpc.call('platform.actuator','get_point', dr_topic, point="signal_payload").get(timeout=15)
dr_topic 是 slipstream_internal/slipstream_hq/33333
非常感谢任何尝试的想法...

当调用平台驱动程序的配置方法时（在配置存储回调期间发生），平台驱动程序根据传递的配置创建一个具有接口 class 的驱动程序实例。如果传递的配置不正确或传递不当，则平台驱动程序将无法实际实例化驱动程序，因此它不会被添加到“self.instances”字典（上文）中。当您调用平台驱动程序时，您会包含一个主题。该路径 必须 匹配映射到“self.instances”字典中的驱动程序实例值的键。
因此，我有几个地方建议进行调查。 1) 将配置重新加载到配置存储中，并在执行此操作时查看 VOLTTRON 日志文件。如果您在 VOLTTRON 日志中没有看到配置文件的字典表示（在详细日志记录模式下 运行），那么您可能给了它一个格式不正确的配置。 2) 仔细检查您在 RPC 调用中使用的主题。如果主题不在“self.instances”字典中，它将抛出错误，因为它要求的键不存在。
您上面发布的配置在我看来是正确的，因此在我看来，RPC 调用中的主题或用于存储配置的命令最有可能是罪魁祸首。
实际上解决这个问题的方法似乎是我同时重新启动了执行器代理、bacnet 代理和主代理。是不是主代理需要重启？
更新
如果您必须在设备的配置存储中更改某些内容，例如使 BACnet 点可写而不是只读；有些东西手指错误地变粗了，这也会导致同样的错误！而且也很难排除故障。
例如在实时系统上，如果您必须通过 vctl 修改如下内容：
vctl config edit platform.driver registry_configs/1100.csv
而且你用粗手指制造了一个语法错误，这也会抛出同样的错误!!!!!
