Schneider Electric 890USE17700 manual Standard, CANopen, Devices, Length, Island Bus

Introduction

Standard	You may also install one or more standard CANopen devices on an island. These
CANopen	devices are not auto-addressable, and they must be installed at the end of the island
Devices	bus. If you want to install standard 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 standard 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 standard CANopen devices cannot be auto-addressed on the island bus, they must be addressed using physical addressing mechanisms on the devices. The standard 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 120 Ω. The rest of the island bus needs to be terminated after the CANopen extension module with an

Length of the	The maximum length of an island bus—the maximum distance between the NIM and
Island Bus	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.
