Cscape Programming via CAN
The NET1 port supports CsCAN Programming Protocol. If a PC has a CAN interface installed (via PCI
card or USB), and the PC CAN port is connected to the XL6/XL6e OCS NET1 port, Cscape can access
the XL6/XL6e OCS for programming and monitoring.
In addition, the XL6/XL6e OCS supports single-point-programming of all XL6/XL6e OCS and other
OCS/RCS devices that are connected to a CAN network. If the PC COM port is connected to the
XL6/XL6e OCS MJ1 serial port, the XL6/XL6e OCS can act as a pass-through gateway allowing Cscape
to access all XL6/XL6e OCS and OCS/RCS devices that are attached to the CAN network.
6.5
Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the NET1 port can exchange digital and analog global
data with other XL6/XL6e OCS or OCS/RCS devices (nodes) attached to the CAN network.
In addition, Put and Get Network Heartbeat function blocks allow nodes on the CAN network to regularly
announce their presence and to detect the presence (or absence) of other nodes on the network.
6.6
Using CAN for I/O Expansion (Network I/O)
Connecting Network I/O devices (SmartStix Modules) to the XL6/XL6e OCS NET1 port, allows the
XL6/XL6e OCS I/O to be economically expanded and distributed. A variety of SmartStix Modules is
available for this purpose.
Note: The V+ connection is not
required on the XL6/XL6e OCS.
The XL6/XL6e OCS network port
is self-powered. Supporting
devices can require this
connection, and this pin can be
used to land the extra wire
required for those devices.
CAN Connector

when using CsCAN network.
