Connecting CANopen and Ethernet POWERLINK

By Christian Schlegel, IXXAT Automation

One solution circumventing the limitations of CANopen (limited bandwidth, limited system extension) would be switching completely to Ethernet POWERLINK. However, for many systems this would be like the tail wagging the dog since the POWERLINK technology is more expensive than the CANopen technology (e.g. cabling costs, hardware costs, system integration costs). Instead of converting a system completely from CANopen to POWERLINK, it often makes sense to build a new system structure using several subsystems. The following two system architectures are possible…
