Enhanced CANopen Devices
You may also install one or more enhanced CANopen devices on an island. These
devices are not auto-addressable, and they must be installed at the end of the island
bus. If you want to install enhanced CANopen devices on an island, you need to use
an STB XBE 2100 CANopen extension module as the last module in the last
segment.
NOTE: If you want to include enhanced CANopen devices in your island, you need
to configure the island using the Advantys Configuration Software, and you need to
configure the island to operate at 500 kbaud.
Because enhanced CANopen devices cannot be auto-addressed on the island bus,
they must be addressed using physical addressing mechanisms on the devices. The
enhanced CANopen devices together with the CANopen extension module form a
sub -network on the island bus that needs to be separately terminated at the
beginning and end. A terminator resistor is included in the STB XBE 2100 CANopen
extension module for one end of the extension sub-network; the last device on the
CANopen extension must also be terminated with a 120 Ω resistor. The rest of the
island bus needs to be terminated after the CANopen extension module with an
STB XMP 1100 termination plate:
1 primary segment
2 NIM
3 STB XBE 1100 EOS bus extension module
4 1 m length STB XCA 1002 bus extension cable
5 extension segment
6 STB XBE 2100 CANopen extension module
7 STB XMP 1100 termination plate
8 typical CANopen cable
9 enhanced CANopen device with 120 Ω termination
Length of the Island Bus
The maximum length of an island bus (the maximum distance between the NIM and
the last device on the island) is 15 m (49.2 ft). This length must take into account the
extension cables between segments, extension cables between preferred modules,
and the space consumed by the devices themselves.
