General Features: |
|
12 |
||
1319 | 13 |
* EtherCAT master implementation conforming to IEC/PAS 62407. |
14 |
- Runs as kernel module for Linux 2.6. |
|
15 |
- Multiple masters possible on one machine. |
|
270 | 16 |
|
1590 | 17 |
* Native EtherCAT-capable versions of standard Linux drivers for wide-spread |
18 |
Ethernet devices, as well as a generic driver for all chips supported by the |
|
19 |
Linux kernel. |
|
20 |
- Interrupt-less operation of Ethernet devices when using native drivers. |
|
21 |
- Easy implementation of additional native Ethernet drivers through common |
|
22 |
device interface. |
|
1319 | 23 |
- Operation possible with any device supported by the standard drivers, |
24 |
including PCMCIA devices. |
|
1590 | 25 |
- For any other hardware, the generic driver can be used. It uses the lower |
26 |
layers of the Linux network stack. |
|
270 | 27 |
|
1319 | 28 |
* Supports any realtime environment through independent architecture. |
29 |
- RTAI, Xenomai, RT-Preempt, etc. |
|
1320 | 30 |
- Operation possible without any realtime extension at all. |
270 | 31 |
|
1319 | 32 |
* Common API for Realtime-Applications in kernel- and userspace. |
33 |
- Requesting and releasing masters. |
|
34 |
- Dynamic slave configuration, even for slaves that are offline. |

- Creation of process data domains (see below). Registration of PDO entries |
1319 | 37 |
for exchange within a domain. |
38 |
- Monitoring the states of masters, slave configurations and domains. |

- SDO handlers for application-triggered CoE transfers (see below). |
1319 | 40 |
- VoE handlers for Vendor-specific mailbox protocols (see below). |
41 |
- Similar userspace implementation of the kernel API via a C-library. |
|
270 | 42 |
- Avoidance of unnecessary copy operations for process data. |
43 |
||
44 |
* Separating slave groups through domains. |
|
45 |
- Handling of multiple slave groups with different sampling rates. |
|
46 |
- Automatic calculation of process data mapping, FMMU- and sync manager |
|
47 |
configuration within the domains. |
|
1319 | 48 |
- Process data exchange can be monitored via a per-domain mechanism. |

* Master finite state machine (FSM). |
1320 | 51 |
- The same state machine runs both in idle mode and in realtime operation. |
52 |
- Bus monitoring: Slave states are read cyclically. Automatic scanning of the |
|
53 |
bus after a topology change. |
|
1319 | 54 |
- Automatic configuration of slaves, if a application-layer state change is |
55 |
requested. |
|
270 | 56 |
|
1364 | 57 |
* Implementation of the "CANopen over EtherCAT" (CoE) mailbox protocol. |
1319 | 58 |
- Configuration of CoE-capable slaves. |

64 |
- Both a switched and a routed EoE network architecture is natively supported |
|
65 |
and configurable with standard tools. |
|
