Note
• A change of the function mode, the baud rate, or Node ID requires a restart of the FX
effective.
• If a configuration BFM is written to while in online mode (BFM #25 bit 4 is ON), BFM #29 bit 5 will be set
ON.
• When BFM #25 bit 7 is ON, the Module is initializing the internal data structures and the BFM, and any TO
command (write access) prohibited. If the BFM is written to, BFM #29 bit 5 will be set to ON.
When BFM #25 bit 7 is bit ON, the only access allowed is to read (FROM) BFM #25 and BFM #29.
Module restart
When restarting the module, set BFM #25 Bit 0 to ON.
In this case, set data that was not saved will be lost.
