CAN1 Port Connector
11.4 Cscape Programming via CAN
The CAN1 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 XL4/XL4 Prime OCS CAN1
port, Cscape can access the XL4/XL4 Prime OCS for programming and monitoring.
In addition, the XL4/XL4 PRIME OCS supports single-point-programming of all XL4/XL4 Prime
OCS and other OCS/RCS devices that are connected to a CAN network. If the PC COM port is
connected to the XL4/XL4 Prime OCS MJ1 serial port, the XL4/XL4 Prime OCS can act as a
pass-through gateway allowing Cscape to access all XL4/XL4 Prime OCS and OCS/RCS
devices that are attached to the CAN network.
11.5 Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the CAN1 port can exchange digital and
analog global data with other XL4/XL4 Prime 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.
11.6 Using CAN for I/O Expansion (Network I/O)
Connecting network I/O devices (SmartStix, SmartBlock, SmartMod, or SmartRail) to the
XL4/XL4 Prime OCS CAN1 port, allows the XL4/XL4 Prime OCS I/O to be economically
expanded and distributed. A variety of modules are available for this purpose.
