7.2.3 Fieldbus Expansions
The fieldbus expansion connectors can be used to extend each CAN circuit with fieldbus
expansions for additional fieldbuses. The signals of the additional fieldbuses are applied to the
corresponding CAN connector.
► Observe information about available fieldbus expansions and the compatibility with CAN
interfaces on www.ixxat.com.
► Install the expansion (see Installation, p. 14).
7.3 MultiCAN Expansion
Fig. 8 MultiCAN expansion
With using a MultiCAN expansion the number of available CAN high-speed channels on a D-Sub 9
connector of a specific CAN interface is doubled and the number of required computer slots is
halved.
MultiCAN-PB is used in conjunction with the standard version.
MultiCAN-PB/LP is used in conjunction with the low-profile version.
7.3.1 MultiCAN-PB
The expansion redirects the channel CAN 3 to the D-Sub 9 connector of CAN 1 and channel CAN
4 to D-Sub 9 connector of CAN 2. The galvanic isolation of CAN channels remains.
The use of the following expansions is not possible:
• CAN expansion board
• fieldbus expansions
Compatibility
The MultiCAN-PB expansion is compatible with the following, galvanically isolated two channel
CAN interfaces (standard version):
• CAN-IB100/PCIe
• CAN-IB200/PCIe
• CAN-IB300/PCI
• CAN-IB400/PCI
