RKC temperature controller
RKC CD and CH series thermostat collection driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “RKC Thermostat” 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: 1; Range: 0~99; 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 two-character labels such as M1, AA, ER, etc., and the station number can be specified with s=2;M1.
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 M1 measured value on the instrument; ASCII numeric text is parsed as a number rather than an IEEE register.
Troubleshooting
- Identifiers are two-character tags; one address accepts only scalar writes. For checksum failures, inspect station, control characters and terminator.
- 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.
