CAN1 & CAN2 Connector Locations
The CAN1 port allows the XL+ OCS to exchange global data with other OCS/RCS controllers
and to access remote Network I/O devices (SmartStix, Smart Blocks and Smart Rail Modules).
The CAN1 port also supports pass-through communications for programming multiple OCS
controllers over the CsCAN network.
CAN2 port supports CsCAN, CANopen, J1939, and DeviceNet Master (layer 3 as a selectable
option
–
one only).
11.2 Port Description
The XL+ OCS CAN ports implement the ISO 11898-2 physical layer and the CAN 2.0A data link
layer standards. Also, since the CAN ports are powered by an internal isolated power supply,
external CAN power is not required.
NOTE: The CAN ports does not supply power to the network.
