Protocol Stacks
Protocol Stack
CANopen / CANopen FD Slave
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 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)
- Synchronization Messages (SYNC Consumer & Producer)
- Layer Setting Services (LSS Slave)
- Time server ( TIME Producer / Consumer)
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.
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.
