Profiles for medical devices – Part 6: Dose measurement system
1 Scope
This specification defines the CANopen device profile for dose measurement systems.
A prerequisite for the conformity to this CANopen device profile is conformity with the
CANopen communication profile. Additionally, in the case that the module is programmable
conformance to the framework for programmable CANopen devices is required. It is
recommended to consulted these specifications in parallel to this device profile specification.
