Verifying an Island Configuration
890USE18000 September 2003 65
If one or more standard CANopen devices are used on an island, the last module
on the last rail of the island shall be a CANopen extension module. A termination
plate shall be installed on the rail after the CANopen extension module.
The address of any standard CANopen device shall not duplicate the address of
an Advantys STB module or a preferred module on the island.
There shall be at least one CANopen device and no more than twelve CANopen
devices after the CANopen extension module
The last module on the island shall be terminated with a 120 Ω resistor.
Design Rules
that May Not Be
Checked by the
Software
Two important design rules are not checked in the build process by the software.
You need to be aware of these rules and incorporate them in the design of your
physical island:
If the last module on the island is a preferred module or a standard CANopen
device, you shall provide120 Ω termination on that module/device.
The maximum length of the physical island shall be no more than 15 m if standard
CANopen devices are not used and no more than 6.5 m if standard CANopen
devices are used. Standard CANopen devices and cables shall be calculated as
part of the total island length.
Validating the
Build
If the configuration is not valid, the build will fail. The Log Window will display the
associated error messages.
If the configuration is valid, the build will succeed. The Log Window will display the
following message: "Build completed successfully".
