CANopen / CANopen FD Slave Protocol Stack

The CANopen / CANopen FD slave protocol stack has been optimized for low resource requirements and is, thus, well suited for intelligent sensors and actuators. The CANopen / CANopen FD protocol stack offers the complete functionality for integration of the CANopen standards CiA 301 (FD: CiA 1301) and CiA 305 into your devices. The following CANopen services are supported:

  • Service Data Objects (SDO / USDO Server)
  • Process Data Objects (PDO Consumer / Producer)
  • Network Management (NMT Slave)
  • Emergency Messages (EMCY Consumer / Producer)
  • Synchronisation Messages (SYNC Consumer / Producer)
  • Layer Setting Services (LSS Slave)
  • Time Server (TIME Producer / Consumer

 

All services can be parameterized during runtime via the application or via the local object dictionary. Users may extend the local object dictionary according to their specific purposes. A variety of device profiles and application profiles are available to complement the protocol stack. Various callback functions can be used to send on messages of the CANopen / CANopen FD protocol stack to the application.

 

The number of PDOs can be configured within a range from 0 to 32 for Transmit-PDOs (TPDO) as well as for Receive-PDOs (RPDO). For any configuration the pre-defined connection set (CIA 301 / 1301) will be respected automatically. In addition, PDO linking can be disabled for safety-critical applications.

 

The option Mini-Master adds the following functions to our CANopen slave protocol stack:

  • SDO Client: parameterization of other CANopen slave devices
  • NMT master: change NMT condition of other CANopen slave devices
  • Network Management (NMT)
  • LSS master: adjustment of bit rates and node ID

 

The option Safety provides an implementation of the European standard EN 50325-5 featuring the following functions:

  • max. 8 SRDOs (SR Data Object)
  • global fail-safe command
  • expansion of the CANopen Slave object dictionary

 

Versatile configuration options allow individual customization to the target system. Example codes facilitate the startup phase, enabling the user to focus on the implementation of their own application. The open CAN driver (CANpie FD) provides the flexibility to use any CAN controller available on the market.
