DrvBrPvi Communicator Driver (Custom)

Functional Description

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

Scope and Version

Source: ScadaV6CommExt/DrvBrPvi.Logic
TFM: net8.0
Version: 6.0.0

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
`Username`	—	Extracted from source; confirm meaning in driver implementation.
`Password`	—	Extracted from source; confirm meaning in driver implementation.
`PviDllPath`	—	Extracted from source; confirm meaning in driver implementation.
`Timeout`	3000	Extracted from source; confirm meaning in driver implementation.
`Arsim`	false	Extracted from source; confirm meaning in driver implementation.
`RetryCount`	10	Extracted from source; confirm meaning in driver implementation.

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/DrvBrPvi.Logic
Common: DrvBrPvi.Common

Overrides

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

CmdLine / template

PollingOptions.CmdLine.Trim();

DeviceConfig properties referenced

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

Line CustomOptions

Key	Default
`Username`	—
`Password`	—
`PviDllPath`	—
`Timeout`	3000
`Arsim`	false
`RetryCount`	10

XML keys (Common)

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

62:             bool arsim = LineContext.LineConfig.CustomOptions.GetValueAsBool("Arsim", false);

Troubleshooting

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