Bus cable
CANopen is based on a linear topology with shielded, two-lead twisted-pair cables and termi-
nal resistances at both bus ends. The shielding is connected to ground at both ends. The
transmission rate depends on the network length and ranges from 125 kbit/s to 1000 kbit/s.
The potential network lengths range from 20 m at 1000 kbit/s to 500 m at 125 kbit/s.

EDS file
The equipment characteristics are described with the aid of the electronic data sheet (EDS) fi-
le), that makes use of any standard bus configuration tool.
You will fin the EDS file and the equipment symbol for integration into a PLC of the product
website of the SP-CANopen module on the Internet (https://eshop.wieland-electric.com/).
