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 RX-371 OCS NET1 port, Cscape can access the
RX-371 OCS for programming and monitoring.
In addition, the RX-371 OCS supports single-point-programming of all OCS devices that are connected to
a CAN network. If the PC COM port is connected to the RX-371 MJ1 serial port, it can act as a pass-
through gateway allowing Cscape to access all OCS 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 OCS 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 NET1 port allows the RX-371 OCS I/O to be
economically expanded and distributed. A variety of SmartStix Modules are available for this purpose.
