EtherCAT® Master Stack

Feature set according to ETG.1500

• Support of the EtherCAT Master (MainDevice) Class-B feature set
• Most important features of the EtherCAT Master Class-A

EtherCAT mailbox protocols

• CoE (CAN over EtherCAT)
• SoE (Servo Drive Profile over EtherCAT)
• EoE (Ethernet over EtherCAT)
• FoE (File Transfer over EtherCAT)
• VoE (Vendor specific)

Synchronization

• Distributed Clocks (DC)
• DC master mode and DC slave mode

Other EtherCAT functionalities

• Cable redundancy: base functions and diagnosis functions
• Slave-to-Slave communication
• Read / write access to SII (Slave Information Interface) [NEW]

EtherCAT network configuration

• Network configuration via ENI information
• Either via the integrated XML parser or via generated source code

EtherCAT communication

• Cyclic communication (PDO) in one or more cyclic tasks with different cycle times
• Acyclic communication via mailbox protocols and EtherCAT commands by the application
• Different modes for the scheduling of cyclic and acyclic frames
• Support of time-triggered send (TTS) feature of Ethernet controller

Diagnosis

• Configurable state monitoring and network supervision
• Statistics and error counters
• Event API for notification of errors in the network

Detailed information is given in the datasheet

Software architecture with flexibility

• The master stack library provides a C API.
• Easy integration in existing applications – the stack does not impose the software architecture to the application.
• The EtherCAT master tasks (cyclic, acyclic) can be driven by the application. Usage in single-threaded or multi-threaded application, main-loop architecture and ISR
• Multiple instances of the master stack are possible in one application.
• Adaptation layer allowing an easy integration of the portable stack and the sample applications on an operating system

Driver for EtherCAT communication

• The EtherCAT network can be accessed via the network stack of the underlying operating system and an existing network driver.
• As alternative, optimized link layer drivers with DMA support are available for common Ethernet controllers.

Optimized for performance

• Zero-copy transfer of cyclic frames via DMA when using an optimized link layer driver
• Direct access to the process image in the cyclic frame via macros and functions
• Cycle time of 100 microseconds and shorter even on small platforms

Optimized for usage also on microcontrollers

• Usage is possible without an operating system based on a main-loop architecture and an ISR
• Usage is possible without a filesystem, network stack, etc.
• Small footprint (ROM, RAM) – stack features which are not necessary can be removed at compile time.
