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: Boolean, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String

Address rules
- Panasonic PLC Mewtocol bit address: X, Y, R, L use decimal WORD and hexadecimal digits, such as R10.A; T and C use decimal contacts, such as T100.
- WORD addresses: DT, LD, F, T, C, K, S, IX, IY, ID; WORD views of X, Y, R, L must be aligned with .0, for example R10.0.
- Continuous bit reading of a single frame is up to 400 points; continuous WORD reading of a single frame is up to 500 WORD, and if it exceeds 27 WORD, the extended frame is automatically used.
- WORD writing must provide complete even-numbered bytes; normal frames have a maximum of 98 business bytes, and extended frames have a maximum of 2028 business bytes.
- Supports serial port, TCP client and transparent TCP server sessions, does not support UDP.
Special methods
| Method | Purpose | Parameters |
|---|---|---|
| ReadPlcModelAsync | Read PLC model | No parameters |
Functions
| Function | Purpose |
|---|---|

Device debug
Enter "Development Configuration → Collection Configuration", select the current device and click "More Functions", then open "Debug".
Dedicated debugging page
Open Development Configuration → Collection Configuration, select the device, and open More Functions → Debug. The following image shows the plugin-specific debug page.
Debugging notes
The dedicated page verification can be completed by reading the PLC model number. There is no writing operation on this page.
Verify the configuration
- Use the plugin-specific debug panel with one confirmed test point or test message.
- Confirm that the returned value or received message matches the device point list.
- Perform writes or control operations only with an approved test point and the site safety procedure.
Troubleshooting
- The debug panel shows no result: Check the required inputs and plugin parameters, then inspect the device or target log for a response or error.
- Special method execution fails: Check method parameters and permissions; control, write or reset methods also need to confirm that the device is in a state that allows operation.
- 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.
