Yudian AI-BUS instruments
AI-BUS instrument protocol collection driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “AI-BUS” 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. |
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: 0; Range: 0~80; 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
- The address uses decimal parameter codes from 0 to 255, and s=1;0 can be used to cover the instrument station numbers from 0 to 80.
Device debug
Enter “Development Configuration → Collection Configuration”, select the current device then open “Protocol Debug” at the top of the workspace.
Read and write
Perform read or write verification according to the current plugin address rules; confirm on-site security and permissions before writing.
Messages
Check the device’s message sending and receiving and protocol logs to locate message format, connection and parsing problems.
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 the raw value of parameter 0 with the instrument; use its manual for units and decimal scaling.
Troubleshooting
- Parameter codes are
0–255and stations0–80; display decimal scaling is separate from register byte order. - 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.
