3.4.3 Connection of CAN
Fig. 10: Connecting the CAN signals to the CAN-CBX station
Generally the CAN signals can be fed via the CAN connector of the first CAN-CBX module of the
CBX station. The signals are then connected through the CAN-CBX station via the InRailBus. To loop
the CAN signals through the CBX station the CAN bus connector of the last CAN-CBX module of the
CAN-CBX station has to be used. The CAN connectors of the CAN-CBX modules which are not at the
ends of the CAN-CBX station must not be connected to the CAN bus, because this would cause
incorrect branching.
A bus termination must be connected to the CAN connector of the CAN-CBX module at the end of the
CBX-InRailBus (see Fig. 10), if the CAN bus ends there.
3.5 Remove the CAN-CBX Module from the InRailBus
If the CAN-CBX module is connected to the InRailBus please proceed as follows:
Release the module from the mounting rail in moving the foot catch (see Fig. 7) downwards (e.g. with
a screwdriver). Now the module is detached from the bottom edge of the mounting rail and can be
removed.
Note:
It is possible to remove individual devices from the CBX station without interrupting
the InRailBus connection, because the contact chain will not be disrupted.
