CHAPTER 11:
CAN COMMUNICATIONS
NOTE:
For additional CAN information, refer to the CAN Networks manual (MAN0799) on the Horner
websites.
11.1 Overview
All XL7/XL7 PRIME OCS models provide two CAN network ports, which are implemented with 5-pin
connectors. The connectors are labeled
CAN1 and CAN2
.

CAN1 & CAN2 Connector Locations
The CAN1 port allows the XL7/XL7 PRIME 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 XL7/XL7 PRIME OCS CAN ports implement the ISO 11898-2 physical layer and the CAN 2.0 A 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 do not supply power to the network.
