DrvModbusGst Communicator Driver (Custom)

Functional Description

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

Scope and Version

  • Source: ScadaV6CommExt/DrvModbusGst.Logic
  • TFM: netstandard2.0
  • Version: 6.0.0

Install and Enable

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

Line and Device Configuration

  1. Create a communication line with the proper channel type.
  2. Add device and set address/timeouts.
  3. 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)

KeyDefaultNote
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。

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/DrvModbusGst.Logic
  • Common: DrvModbusGst.Common

Overrides

OnConnectionSet(), InitDeviceTags(), Session(), SendCommand()

CmdLine / template

  • PollingOptions.CmdLine.Trim();

DeviceConfig properties referenced

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

Line CustomOptions

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

856:         public override void Session()
857:         {
858:             base.Session();

Troubleshooting

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