19.1.8 MBUS_WRITE_RAW
The MBUS_WRITE_RAW FB sends a frame to the specified M-Bus slave.

the beginning of the procedure
- TIMEOUT : timeout, in seconds
- C_FIELD : the frame C Field value (see M-Bus protocol specification)
- CI_FIELD : the frame CI Field value (see M-Bus protocol specification)
- DATA[] : the frame User Data field (see M-Bus protocol specification)
- DATA_LEN : the length, i.e. the number of bytes, in the frame User Data field
- DEBUG : when this parameter is set to TRUE, the file /log/mbus_prot.log is
