LocalCAN bus groups are formed by joining MSC IIs together at the Q-connectors.
The modules within LocalCAN bus groups communicate over the internal
LocalCAN bus.
Observe the following when establishing LocalCAN bus groups:
• The number of modules in a LocalCAN bus group is limited to 64 because
CAN bus networks can only include a maximum of 64-network
stations.
�-"7.5.5.3-Number of Network Stations" on page 58
• The switchable CAN bus termination resistor of the MSC II can be used
as a termination resistor for the LocalCAN bus group.
�-"10.15.1-CAN Bus Termination Resistor" on page 110
• If a QEBUS-CAN is attached to the right, then the LocalCAN bus can be
made available (using the QEBUS-CAN) for other CAN bus network stations
that do not belong to the LocalCAN bus group.
