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.
