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 |
|
1319 | 17 |
* EtherCAT-capable versions of standard Linux drivers for wide-spread |
18 |
Ethernet devices. |
|
19 |
- Interrupt-less operation of Ethernet devices. |
|
20 |
- Easy implementation of additional Ethernet drivers through common device |
|
270 | 21 |
interface of the master. |
1319 | 22 |
- Operation possible with any device supported by the standard drivers, |
23 |
including PCMCIA devices. |
|
270 | 24 |
|
1319 | 25 |
* Supports any realtime environment through independent architecture. |
26 |
- RTAI, Xenomai, RT-Preempt, etc. |
|
27 |
- Operation possible even without any realtime extension. |
|
270 | 28 |
|
1319 | 29 |
* Common API for Realtime-Applications in kernel- and userspace. |
30 |
- Requesting and releasing masters. |
|
31 |
- Dynamic slave configuration, even for slaves that are offline. |
|
32 |
- Detailed configuration of the slaves' Pdos and Sdos. |
|
33 |
- Creation of process data domains (see below). Registration of Pdo entries |
|
34 |
for exchange within a domain. |
|
35 |
- Monitoring the states of masters, slave configurations and domains. |
|
36 |
- Sdo handlers for application-triggered CoE transfers (see below). |
|
37 |
- VoE handlers for Vendor-specific mailbox protocols (see below). |
|
38 |
- Similar userspace implementation of the kernel API via a C-library. |
|
270 | 39 |
- Avoidance of unnecessary copy operations for process data. |
40 |
||
41 |
* Separating slave groups through domains. |
|
42 |
- Handling of multiple slave groups with different sampling rates. |
|
43 |
- Automatic calculation of process data mapping, FMMU- and sync manager |
|
44 |
configuration within the domains. |
|
1319 | 45 |
- Process data exchange can be monitored via a per-domain mechanism. |

|
47 |
* Master finite state machine (FSM). |
1319 | 48 |
- The same state machine runs when the master is idle and also when an |
49 |
application is connected. |
|
50 |
- Bus monitoring. Slave states are read cyclically. Automatic scanning of the |
|
51 |
bus on a topology change. |
|
52 |
- Automatic configuration of slaves, if a application-layer state change is |
|
53 |
requested. |
|
270 | 54 |
|
555 | 55 |
* Implementation of the CANopen-over-EtherCAT (CoE) protocol. |
1319 | 56 |
- Configuration of CoE-capable slaves. |

|
57 |
- Sdo information service (dictionary listing). |
1319 | 58 |
- Sdo transfers via the application interface and the command-line tool. |
270 | 59 |
|
555 | 60 |
* Implementation of the Ethernet-over-EtherCAT (EoE) protocol. |
1319 | 61 |
- Creates a virtual network interface for any EoE-capable slave. |
62 |
- Natively supports either a switched or a routed EoE network |
|
63 |
architecture. |
|
270 | 64 |
|
1319 | 65 |
* Userspace command-line tool 'ethercat'. |
66 |
- Detailed information about master, slaves, domains and bus configuration. |
|
67 |
- Reading/Writing alias addresses. |
|
68 |
- Listing slave configurations. |
|
69 |
- Viewing process data. |
|
70 |
- Sdo download/upload; listing Sdo dictionaries. |
|
71 |
- Access to slave registers. |
|
72 |
- Slave SII (EEPROM) access. |
|
73 |
- Requesting application-layer states. |
|
74 |
- Generation of slave description XML from existing slaves. |
|
270 | 75 |
|
1319 | 76 |
* Seamless integration in any GNU/Linux distribution. |
77 |
- Master and Ethernet device configuration via sysconfig file. |
|
555 | 78 |
- "Linux standard base"-compatible init script for master control. |
270 | 79 |
|
1319 | 80 |
* Virtual read-only network interface for debugging and traffic monitoring |
81 |
purposes (using Wireshark, etc.). No additional hardware necessary. |
