TIANXIN flow instruments
TIANXIN instrument protocol address read and write driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “TIANXINMaster” in “Collection Plugin”.
Supported channels and data types
| Channel type | Pre-configuration check |
|---|---|
| TCP Client | Confirm network reachability of the device IP, port, and gateway to the device. |
| TCP server | Confirm that the local listening address and port are available, and allow on-site devices to actively connect to the gateway. |
| Serial Port | Confirm that the serial port is not occupied by other programs and maintains the same baud rate, data bits, stop bits and parity bits as the device. |
| UDP | Confirm the local binding address, port and firewall rules, and check the source of the packet. |
Optional data types: Boolean, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String, Decimal
This list describes types allowed by the plugin editor. Address width, arrays, string length and read/write restrictions still follow this page; it does not mean that every address supports every type.
Plugin properties
Protocol parameters
| Setting | Description |
|---|---|
| Default station number | Default: 1; fill in: text input. Set the default station number used when the station number is not specified separately in the variable address. |
Connection configuration
| Setting | Description |
|---|---|
| DTU ID | Fill in: text input. Sets the identifier used to identify the current device connection through the DTU service. |
Address rules
- TIANXIN address format: [S=station number;] data item, when the station number is not filled in, the default station number configured by the device is used.
- Data items: Time, FlowRate, TotalAmount, Temp, Pressure, A1_7, A1_6, A1_5, A1_4, A1_3, A1_2, A1_1, A1_0, S_7, S_6, S_5, S_4, S_3, S_2, S_1, S_0.
- Example: FlowRate;S=1;TotalAmount;S=2;A1_7.
Device debug
Enter “Development Configuration → Collection Configuration”, select the current device then open “Protocol Debug” at the top of the workspace.
Functions
| Function | Purpose |
|---|---|
| Read and write | Read a confirmed point and write only to an approved test point. |
| Messages | View sent and received frames, protocol fields, and error details. |
Verify the configuration
Compare with the instantaneous-flow display; use instrument-configured units/scaling. Time uses String separately.
Troubleshooting
- Distinguish FlowRate, TotalAmount and status selectors. Match station and field before choosing a type; one type does not describe every item.
- The serial port device does not respond: Confirm that the serial port is not occupied, and check the baud rate, data bits, stop bits and parity bits.
