Yamatake Digitron CPL instruments
Azbil Yamatake Digitron CPL instrument address read and write driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “DigitronCplMaster” in “Collection Plugin”.
Supported channels and data types
| Channel type | Pre-configuration check |
|---|---|
| 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. |
| 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. |
Optional data types: Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String
Plugin properties
Protocol parameters
| Setting | Description |
|---|---|
| Default station number | Default: 1; Range: 0~255; Fill in: text input. Default station number; two-digit hexadecimal line format, the address can be overwritten with s=0..255 |
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
- Digitron CPL addresses use decimal WORD locations, such as 0, 100, 65520.
- You can use s=0..255; to overwrite the default station number, for example, s=2;100; non-two-byte types automatically occupy consecutive WORDs.
- A single RS/WS can access up to 16 WORD, and larger collection ranges are executed separately according to the read plan.
- The current protocol does not support Boolean bit addresses, writes must consist of complete WORD.
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 the raw WORD at parameter 100; validate word order and scaling separately for wider types.
Troubleshooting
- Boolean bit addresses are unsupported and writes require complete WORDs. Each RS/WS request is limited to 16 WORDs.
- 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.
