BUS ADDR Input of the device address (factory setting: 63)
The address can be changed via the keys at the device or via the bus. After each
change, all Connection Objects are deleted followed by the execution of the normal
Start-Up procedure for network access by a subscriber (as after a Reset or Power-
Up).
ADDR XXX
Values from 0 .. 63 can be set via the arrow keys; confirmation takes place with the
MANUAL/AUTOMATIC key.
BUS RATE The baud rate can be changed via the keys at the device or via the bus. In each
case a change has no effect until a Reset (transmission of a Reset message to the
Identity Object) or a Power-Up is performed. That is to say, if the changed attribute
baud rate is accessed before a Reset or Power-Up, the entered (changed) value
does not agree with the still current (to be changed) baud rate of the network.
KBD XXX
Selection of 125kbit/s, 250 kbit/s or 500kbit/s.
BUS FAIL
