DAM3601 Temperature Module
Purpose
This plugin collects DAM3601 temperature input registers using Modbus RTU framing and reads all 128 Celsius channels in one snapshot operation. It is named Dam3601Master in the device selector.
Open the plugin and supported scope
Create a serial, TCP client, or TCP server channel, then create a device using Dam3601Master. TCP channels carry RTU frames. UDP is not supported. Variable data types are Int16 and UInt16.
Plugin properties
| Setting | Default | Description |
|---|---|---|
| Modbus framing | ModbusRtu | Fixed to RTU. |
| Module station | 1 | Must match the module address. |
| Data format | CDAB | Default temperature raw-value order. |
| Input registers per frame | 120 | Range 1 to 125. A complete 128-channel snapshot is split into two frames. |
| Send delay | 200 ms | Default delay between the two reads. |
| DTU ID | - | Used for a DTU service connection. |
Keep the other common Modbus batch limits at their defaults.
Address and special method
Use input-register addresses from the device point list in 30001 notation for cyclic variables. ReadAllTemperaturesAsync takes no parameters and reads channels 0 through 127.
| Method | Purpose | Parameters |
|---|---|---|
ReadAllTemperaturesAsync | Read all 128 Celsius temperatures | - |
Functions
| Function | Purpose |
|---|---|
| Read or monitor | Read current values or monitor the latest device update. |
Device debug
Open Development Configuration → Collection Configuration, select the DAM3601 device and click More Functions, then open Debug → Protocol Debug · Dam3601.
| Feature | Purpose |
|---|---|
| Read all temperatures | Reads and displays channels 0 through 127 in two frames. This panel has no write operation. |
Verify the configuration
- Confirm that the device is online and select Read All Temperatures.
- Compare one connected sensor channel with the field temperature or calibration source.
- Confirm unused and fault-channel behavior against the module manual before creating cyclic variables.
Troubleshooting
| Symptom | Check |
|---|---|
| No response | RTU framing, station, serial settings, TCP pass-through, and network. |
| Only some channels return | Input-register frame limit, second response, and send delay. |
| Temperature is clearly incorrect | Channel wiring, sensor type, data format, and module range. |
