The Panasonic FP7 Series Communication Unit User Manual provides safety instructions, wiring, communication setup, and troubleshooting details.
This manual describes the FP7 series communication unit, its safety precautions, functional features, and the various communication protocols it supports. It guides users through installation, wiring, I/O allocation, and configuration of PLC Link, MEWTOCOL, MODBUS RTU, and general‑purpose communication functions.
Key sections include safety warnings, detailed wiring diagrams for COM ports and extension cassettes, step‑by‑step procedures for setting communication parameters, troubleshooting tips, and a full specification table covering USB, RS‑232C/RS‑485 interfaces and protocol settings.
| USB port speed | USB2.0 FULL SPEED |
|---|---|
| COM0 port transmission distance | 15 m |
| Supported baud rates | 300‑230400 bit/s |
| Data length options | 7 bits or 8 bits |
| Stop bit options | 1 bit or 2 bits |
| Parity options | None, Odd, Even |
| COM0 interface type | 3‑wire 1‑channel RS‑232C |
The FP7 unit supports MEWTOCOL‑COM, MEWTOCOL7‑COM, MODBUS‑RTU, general‑purpose communication, and PLC link functions.
The COM0 port can be wired up to 15 m in length.
Use the UNITSEL instruction followed by the PMGET instruction, specifying slot, port, and the parameter type (communication mode, unit number, baud rate, etc.).
When the baud rate is 38 400 bps or higher, use a cable no longer than 3 m and a shielded wire for RS‑232C.
