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/DrvLafei485.Logic
Common: DrvLafei485.Common

Overrides

OnCommLineStart(), OnCommLineTerminate(), SendCommand()

CmdLine / template

未匹配到 PollingOptions.CmdLine 单行片段。

DeviceConfig properties referenced

Property	Note
未检测到 DeviceConfig.* 引用（可能使用基类封装）。

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）。

XML keys (Common)

Node	Note
未在 Common 中解析到 GetChildAs*/AppendElem 节点（或无 Common 工程）。

Code excerpt

See source files.

Troubleshooting

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