DrvSiemensS7Plus Communicator Driver (Custom)

Functional Description

DrvSiemensS7Plus is a custom Communicator driver in ScadaV6CommExt for field device connectivity. Protocol details follow the source implementation.

Scope and Version

Source: ScadaV6CommExt/DrvSiemensS7Plus.Logic
TFM: net8.0
Version: 6.2.0

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

22: protected DeviceTemplate deviceTemplate;
31: ConnectionRequired = false; //不使用默认连接池
249: var ipPort = deviceAddr.Split(new char[] { ':' }, StringSplitOptions.RemoveEmptyEntries);
250: siemensS7Net = new SiemensS7NetPlus(ipPort[0].Trim(), int.Parse(ipPort[1]));
277: string fileName = PollingOptions.CmdLine.Trim();
336: deviceTemplate = DriverUtils.TemplateFactory.CreateDeviceTemplate();

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/DrvSiemensS7Plus.Logic
Common: DrvSiemensS7Plus.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

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）。

243:             ExecWriteToLog($"StartPlcConn: deviceAddr:{deviceAddr}, slot: {slot}");

271:         /// 
272:         public override void InitDeviceTags()
273:         {
274:             // PrepareAuthTemplate();

274:             // PrepareAuthTemplate();
275:             string fileName = PollingOptions.CmdLine.Trim();
276:             PrepareTemplate(fileName);
277:             int tagInd = 0;

Troubleshooting

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