DrvBACnet Communicator Driver (Custom)

Functional Description

DrvBACnet is a custom Communicator driver in ScadaV6CommExt for field device connectivity. Protocol details follow the source implementation.

Scope and Version

Source: ScadaV6CommExt/DrvBACnet.Logic
TFM: net8.0
Version: 6.4.0

Install and Enable

Deploy driver binaries to Communicator folders.
Activate driver in Administrator → Communicator → Drivers.
Upload configuration and restart Communicator.

Line and Device Configuration

Create a communication line with the proper channel type.
Add device and set address/timeouts.
Set polling options and CmdLine as required by this driver; see Functional notes and configuration (template and source) below for file names, address format, and line keys.

CustomOptions (extracted)

Key	Default	Note
未在源码中匹配到明显的 `GetValueAs*` 调用，请在 Administrator 中打开该驱动的设备/线路配置界面逐项确认。

Code hints

24: protected DeviceTemplate deviceTemplate; //KP 数据使用的设备模板
26: private int Timeout = 10;//超时时间，秒
36: ConnectionRequired = false; //不使用默认连接池
142: var ipPort = deviceAddr.Split(new char[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
143: var port = int.Parse(ipPort[1]);
144: bacnetClient.RemoteWhoIs(ipPort[0], int.Parse(ipPort[1]));
195: string fileName = PollingOptions.CmdLine.Trim();
229: deviceTemplate = new DeviceTemplate();

Functional notes and configuration (template and source)

Derived from Logic/Common and device template XML: driver behavior and the Administrator/Communicator fields to set (address, CmdLine, line CustomOptions, template nodes).

Logic location

ScadaV6CommExt/DrvBACnet.Logic
Common: DrvBACnet.Common

Overrides

Session(), SendCommand(), OnCommLineStart(), OnCommLineTerminate(), InitDeviceTags()

CmdLine / template

PollingOptions.CmdLine.Trim();

DeviceConfig properties referenced

Property	Note
`StrAddress`	源码中对 DeviceConfig 的引用
`NumAddress`	源码中对 DeviceConfig 的引用

Line CustomOptions

Key	Default
未在 Logic 中检测到 CustomOptions.GetValueAs*（可能全部从设备模板 XML 读取）。

148: 
149:             Log.WriteAction($"Local bacnet client started, remote address is {DeviceConfig.StrAddress}!");
150:         }
151: 

190:         /// 
191:         public override void InitDeviceTags()
192:         {
193:             string fileName = PollingOptions.CmdLine.Trim();

Troubleshooting

No data: line, address, template, connectivity.
Template load errors: check logs.
Options ignored: verify option scope (line vs device).
