CANopenIA Stand-Alone Mode
CANopenIA solutions implementing the stand-alone mode directly implement an
entire CANopen Device Profile including both CANopen and application code. These
implementations provide the fastest design cycles, as the modules or chips
directly implement complete CANopen nodes.
The block diagram above shows the components of a CANopenIA stand-alone
system. Digital and analog inputs and outputs are provided as they are available
in the specific CANopenIA hardware (microcontroller used). Optional
high-resolution analog components might be available via SPI or I2C
interface. How the process and configuration data is stored in the process image
is determined by the setup information stored in the EEPROM or other
non-volatile memory available in the CANopenIA device. The setup information
also determines how the process data is made available via CANopen SDOs and PDOs
(Service Data Objects and Process Data Objects).
When designing a device with a CANopenIA stand-alone solution, one can focus
on providing the digital and analog inputs and outputs as all CANopen aspects
are completely handled by the CANopenIA device.
