Fuji SPB master
Fuji SPB protocol PLC address read and write driver
Open the plugin
Enter “Development Configuration → Collection Configuration”, create a device and select “FujiSpbMaster” 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: Boolean, Int16, UInt16, Int32, UInt32, Float, String
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 |
|---|---|
| PLC station number | Default: 1; fill in: text input. PLC station number; SPB requests to use two-digit uppercase hexadecimal station number |
Address rules
- Fuji SPB WORD address: Y, X, M, L, TC, CC, TN, CN, D, R, W, such as D100, TN20.
- Boolean address can use WORD address and bit number, such as D10.12; X, Y, M, L, TC, CC can also directly use continuous bit number, such as M35.
- Single read 1 to 105 WORD, single write 1 to 103 WORD; Boolean write only writes one bit at a time.
- PLC communication parameters must be configured without BCC and CRLF end code enabled.
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
Monitor D100 online in the PLC engineering tool, compare its value with the gateway variable and confirm advancing sample times.
Troubleshooting
- For response parsing failures, check BCC and CRLF first; reads allow 105 WORDs and writes 103.
- 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.
