5.4 Cscape Programming via CAN

The CsCAN 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 QX BPxx CsCAN port, Cscape can access the

QX BPxx for programming and monitoring.

In addition, the QX BPxx supports single-point-programming of all QX BPxx and other OCS/RCS devices

that are connected to a CAN network. If the PC COM port is connected to the QX BPxx MJ1 serial port

(see Error! Reference source not found.), the QX BPxx can act as a pass-through gateway allowing

Cscape to access all QX BPxx and OCS/RCS devices that are attached to the CAN network.

5.5 Ladder-Controlled CAN Communication

Using Put and Get Network Words function blocks, the CsCAN port can exchange digital and analog

global data with other QX BPxx 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.

5.6 Using CAN for I/O Expansion (Network I/O)

Connecting Network I/O devices (SmartStix Modules) to the QX BPxx CsCAN port, allows the QX BPxx

I/O to be economically expanded and distributed. A variety of SmartStix Modules are available for this

purpose.
