General Features: |
|
10 |
||
11 |
* Runs as kernel module for Linux 2.6. |
|
12 |
||
13 |
* Comes with EtherCAT-capable network driver for RTL8139 and compatible |
|
14 |
network interface cards. |
|
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. |
|
24 |
- Runs well even without realtime extensions. |
|
25 |
||
26 |
* Common kernel interface, for realtime modules using EtherCAT functionality. |
|
27 |
- Synchronous and asynchronous sending and receiving of frames. |
|
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. |
|
34 |
||
35 |
* Master finite state machine (FSM). Thus: |
|
36 |
- Bus monitoring during realtime operation. |
|
37 |
- Automatic reconfiguration of slaves on bus power failure during realtime |
|
38 |
operation. |
|
39 |
- Controlling of slave states during realtime operation. |
|

|
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 |
||
45 |
* Implements the CANopen-over-EtherCAT (CoE) protocol. |
|
46 |
- Configuration of CoE-capable slaves via SDO interface. |
|
47 |
- SDO dictionary listing. |
|
48 |
||
49 |
* Implements the Ethernet-over-EtherCAT (EoE) protocol. |
|
50 |
- Creates virtual network devices that are automatically coupled to |
|
51 |
EoE-capable slaves. |
|
52 |
- Thus natively supports either a switched or a routed EoE network |
|
53 |
architecture. |
|
54 |
||
55 |
* User space interface via the System Filesystem (SysFS). |
|
56 |
- User space tool for bus visualisation. |
|
57 |
- Slave EĀ²PROM image reading and writing. |
|
58 |
||
59 |
* Seamless integration in your favourite Linux distibution. |
|
60 |
- Master and network device configuration via sysconfig files. |
|
61 |
- UnitedLinux compatible init script for master control. |
|
62 |
||
63 |
* Virtual read-only network interface for debugging purposes and for |
|
64 |
"sniffing" the EtherCAT traffic (through Ethereal, or others). |
