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 OCS CAN1 port, Cscape
can access the XL7 OCS for programming and monitoring.
In addition, the XL7 OCS supports single-point-programming of all XL7 OCS and other
OCS/RCS devices that are connected to the CAN1 port network. If the PC COM port is
connected to the XL7 OCS MJ1 serial port, the XL7 OCS can act as a pass-through gateway
allowing Cscape to access all XL7 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 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
OCS CAN1 or CAN2 port, allows the XL7 OCS I/O to be economically expanded and distributed.
A variety of modules are available for this purpose.
