cards. |
270 | 15 |
- Interrupt-less network driver operation. |
16 |
- Easy implementation of additional network drivers through common device |
|
17 |
interface of the master. |
|
18 |
- Runs even with PCMCIA cards. |
|
19 |
||
20 |
* Supports multiple EtherCAT masters on one machine. |
|
21 |
||
22 |
* Supports any realtime extension through independent architecture. |
|
23 |
- RTAI, IPIPE, ADEOS, etc. |
|
555 | 24 |
- Runs well even without realtime extension. |
270 | 25 |
|
555 | 26 |
* Common kernel interface for realtime modules using EtherCAT functionality. |
27 |
- Synchronous transmission and reception of EtherCAT frames. |
|
270 | 28 |
- Avoidance of unnecessary copy operations for process data. |
29 |
||
30 |
* Separating slave groups through domains. |
|
31 |
- Handling of multiple slave groups with different sampling rates. |
|
32 |
- Automatic calculation of process data mapping, FMMU- and sync manager |
|
33 |
configuration within the domains. |

- Setting slave states during realtime operation. |
270 | 40 |
|
555 | 41 |
* Special IDLE mode, when master is not in use. |
270 | 42 |
- Automatic scanning of slaves upon topology changes. |
43 |
- Bus visualisation and EoE processing without realtime process connected. |
|
44 |

555 | 50 |
* Implementation of the Ethernet-over-EtherCAT (EoE) protocol. |
270 | 51 |
- Creates virtual network devices that are automatically coupled to |
52 |
EoE-capable slaves. |
|
53 |
- Thus natively supports either a switched or a routed EoE network |
|
555 | 54 |
architecture with standard GNU/Linux tools. |
