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 XL7/XL7 PRIME OCS CAN1 port, Cscape can access the
XL7/XL7 PRIME OCS for programming and monitoring.
In addition, the XL7/XL7 PRIME OCS supports single-point-programming of all XL7/XL7 PRIME OCS and
other OCS/RCS devices that are connected to the CAN1 port network. If the PC COM port is connected
to the XL7/XL7 PRIME OCS MJ1 serial port, the XL7/XL7 PRIME OCS can act as a pass-through gateway
allowing Cscape to access all XL7/XL7 PRIME OCS and OCS/RCS devices that are attached to the CAN1
port network.
11.5 Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the CAN 1 port can exchange digital and analog global
data with other XL7/XL7 PRIME OCS or OCS/RCS devices (nodes) attached to the CAN1 port network.
In addition, Put and Get Network Heartbeat function blocks allow nodes on the CAN 1 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 XL7/XL7 PRIME
OCS CAN1 or CAN2 port, allows the XL7/XL7 PRIME OCS I/O to be economically expanded and distributed.
A variety of modules are available for this purpose.
