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