Cscape Programming via CAN
The NET1 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 XLe/XLt NET1 port, Cscape can access the
XLe/XLt for programming and monitoring.
In addition, the XLe/XLt supports single-point-programming of all XLe/XLt and other OCS/RCS devices
that are connected to a CAN network. If the PC COM port is connected to the XLe/XLt MJ1 serial port
(see CHAPTER 5), the XLe/XLt can act as a pass-through gateway allowing Cscape to access all
XLe/XLt and OCS/RCS devices that are attached to the CAN network.
6.5
Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the NET1 port can exchange digital and analog global
data with other XLe/XLt 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.
6.6
Using CAN for I/O Expansion (Network I/O)
Connecting Network I/O devices (SmartStix Modules) to the XLe/XLt NET1 port, allows the XLe/XLt I/O to
be economically expanded and distributed. A variety of SmartStix Modules is available for this purpose.
