7.14.2.3 X300 - signal bus
If a system of b maXX devices is installed with signal bus connection, then all devices are
connected with one another via the signal bus. The bus including the supply unit can be
scanned by each participant and individual signals can be set. Via this bus the supply unit
can indicate errors to the axes, so that the individual axes can react. Each axis can gen-
erate messages to the other axes, for example failures, ballast resistors on or warning
signal bus.
NOTE!
Dependent on the type of the used device
BM3XXX-XXXX-XXXXX[-X]-XXX1X
up to 12 devices can be connected
or
BM3XXX-XXXX-XXXXX[-X]-XXX2X
up to 30 devices can be connected.
