Standard

CANopen

Devices

An island bus can support standard CANopen devices as well as Advantys STB I/O

modules and preferred modules. A maximum of 12 standard CAN open devices can

be added to an island. They do count as part of the 32-module system limit.

Standard CANopen devices are not mounted in segments. They are added at the

end of the primary segment or the last segment on the island. The segment before

the standard CANopen device/s are connected must end with an STB XBE 2100

CANopen extension module (in a STB XBA 2000 base) followed by an

STB XMP 1100 termination plate. The CANopen extension module has a 9 pin

standard open style receptacle that connects to your supplied extension cable. The

last CANopen device must be terminated with a 120 Ω resistor. This is usually a

switch located on the standard CANopen device itself or it may need to be hard

wired in. Only the CAN H and CAN L communication signal is passed from the last

segment to the standard CANopen device/s.

The following illustration shows a primary segment connected to two standard

CANopen devices.

Note: The use of CANopen devices on systems using 800 kBd reduces the

maximum island length to 6.5 m (21.3 ft).

Note: Advantys STB supports all V4 standard CANopen devices.
