10.4 i3 configurator Programming via CAN
The CAN port supports iCAN Programming Protocol. If a PC has a CAN interface installed (via PCI card or
USB), and the PC CAN port is connected to the I3N CAN port, i3 configurator can access the I3N for
programming and monitoring.
In addition, the I3N supports single-point-programming of all I3N and other i3 devices that are connected
to the CAN port network. If the PC COM port is connected to the I3N MJ1 serial port, the I3N can act as a
pass-through gateway allowing i3 configurator to access all I3N and i3 devices that are attached to the
CAN port network.
10.5 Ladder-Controlled CAN Communication
Using Put and Get Network Words function blocks, the CAN port can exchange digital and analog global
data with other I3N or other i3 devices (nodes) attached to the CAN port network.
In addition, Put and Get Network Heartbeat function blocks allow nodes on the CAN port network to
regularly announce their presence and to detect the presence (or absence) of other nodes on the network.
10.6 Using CAN for I/O Expansion (Network I/O)
Connecting Network I/O devices to the I3N CAN port allows the I3N I/O to be economically expanded and
distributed. A variety of modules are available for this purpose.
