volttron - volttron 对 rpc 调用 get_point 进行故障排除

问题描述

有没有机会对如何解决get_point对 BACnet 设备的简单 rpc 调用进行故障排除？我在 rpc 调用上做的事情引发了这个错误：'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",
    "Units": "percent",
    "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"
}

我认为我的代理代码有问题，dr_level = self.vip.rpc.call如下面的片段所示，因为代码在以下代码错误之后出现ACTUATOR AGENT SCHEDULE SUCCESS：

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

任何尝试的想法都非常感谢......

解决方案

实际上解决这个问题的方法是我同时重新启动了执行器代理、bacnet 代理和 masteragent。可能是需要重新启动的主代理吗？

更新

如果您必须更改设备的配置存储中的某些内容，例如使 BACnet 点可写而不是只读；并且错误地手指变胖了，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 修改类似这样的内容：

vctl config edit platform.driver registry_configs/1100.csv

而且你用粗手指创建了一个语法错误，这也会引发同样的错误！！！！！！
