6.4  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. 
6.5  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. 
6.6  Using CAN for I/O Expansion (Network I/O) 
Connecting Network I/O  devices (SmartStix, SmartBlock 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.
