USS baud rate
(USS baud rate)
S
0 ... 8
{ 3 }
Setting of the transfer rate (transfer speed) via the RS485 interface. All bus participants must
have the same baud rate setting.
SK 54xE and above:
0 = 4,800 Baud 4 = 57,600 Baud
1 = 9,600 Baud 5 = 115,200 Baud
2 = 19,200 Baud 6 = 187,750 Baud
3 = 38,400 Baud 7 = 230,400 Baud
8 = 460,800 Baud
NOTE: For communication via Modbus (available for SK 540E and above) a transfer rate of
maximum 38400 Baud must be set.

Telegram time-out
(Telegram time out)
S
-0.1 / 0.0 /
0.1 ... 1000 s
{ 0.0 }
Monitoring function of the active bus interface. Following receipt of a valid telegram, the next one
must arrive within the set period. Otherwise the FI reports an error and switches off with the error
message E010 >Bus Time Out<.
0.0 = Off: Monitoring is switched off.
-0.1 = No error: Even if communication between BusBox and FI is interrupted (e.g. 24V error,
Box removed, etc.), the FI will continue to operate unchanged.

CAN baud rate
(CAN baud rate)
0 ... 7
{ 4 }
Used to set the transfer rate (transfer speed) via the CANbus interface. All bus participants must
have the same baud rate setting. With the use of the CANopen technology unit, settings from this
parameter are only valid if the BAUD rotary coding switch on the technology unit has been set to
PGM.
0 = 10kBaud
1 = 20kBaud
2 = 50kBaud
3 = 100kBaud
4 = 125kBaud
5 = 250kBaud
6 = 500kBaud
7 = 1MBaud *
(for test purposes
only)
*) Reliable operation cannot be guaranteed
Information Data takeover
The baud rate is only read after a Power On, a Reset Node message or a Power On of the
24V bus supply.
