DrvDLT645 Communicator Driver (Custom)

Functional Description

DrvDLT645 is a custom Communicator driver in ScadaV6CommExt for field device connectivity. Protocol details follow the source implementation.

Scope and Version

Source: ScadaV6CommExt/DrvDLT645.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
`RetryCount`	—	Extracted from source; confirm meaning in driver implementation.
`Station`	—	Extracted from source; confirm meaning in driver implementation.
`EnableCodeFE`	—	Extracted from source; confirm meaning in driver implementation.
`UseSecurityResquest`	—	Extracted from source; confirm meaning in driver implementation.
`Password`	—	Extracted from source; confirm meaning in driver implementation.
`OpCode`	—	Extracted from source; confirm meaning in driver implementation.

88:         public override void InitDeviceTags()
89:         {
90:             string fileName = PollingOptions.CmdLine.Trim();

89:         {
90:             string fileName = PollingOptions.CmdLine.Trim();
91:             deviceTemplate = new DeviceTemplate();
92:             if (!deviceTemplate.Load(Storage, fileName, out string errMsg))

100:                 //初始化点位
101:                 plcDeviceSession.InitDeviceTags(DeviceTags, deviceTemplate);
102: 
103:                 CanSendCommands = deviceTemplate.Cmds.Count > 0;

106:             InitPlcConnection();
107:             Log.WriteAction($"InitDeviceTags -> Line running");
108:         }
109: 

111: 
112:         public override void Session()
113:         {
114:             base.Session();

113:         {
114:             base.Session();
115:             if (deviceTemplate == null)
116:             {

Troubleshooting

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