1. 0:00Hello all, welcome to Aank Systems
2. 0:02YouTube channel. In this session, the
3. 0:04intricate canopen protocol is explained
4. 0:06in a straightforward manner. Ready to
5. 0:08dive in? Can open is a communication
6. 0:11protocol built on the canvas
7. 0:13specifically designed for industrial
8. 0:15applications such as motion control,
9. 0:18robotics, medical devices, and
10. 0:20automotive uses. This protocol
11. 0:22facilitates interoperability between
12. 0:24devices nodes and provides standardized
13. 0:27methods for configuring devices both
14. 0:29during and after
15. 0:30installation. Structure of kenopen can
16. 0:33be understood within the context of the
17. 0:35seven layer OSI model where the canvas
18. 0:37operates at the physical and data link
19. 0:40layers. Understanding Ken Open requires
20. 0:43knowledge of several key concepts
21. 0:45including communication models,
22. 0:47communication protocols, device states,
23. 0:49object dictionaries, electronic data
24. 0:52sheets, and device
25. 0:54profiles. There are three main models
26. 0:56for communication. The master or slave
27. 0:59model where a master node requests data
28. 1:01from slave
29. 1:02[Music]
30. 1:03nodes. The client or server model which
31. 1:06facilitates data requests and
32. 1:09responses. And the producer or consumer
33. 1:12model where data is broadcasted from a
34. 1:14producer to a
35. 1:17consumer. Central to CAN opens
36. 1:19functionality is the ability to encode
37. 1:21communication within CAN frames using
38. 1:24identifiers known as communication
39. 1:25object identifiers.
40. 1:27There are also seven service types used
41. 1:29for controlling can open devices
42. 1:31including network management
43. 1:35NMT process data objects
44. 1:39[Music]
45. 1:40PDO and service data objects
46. 1:46SDO. The object dictionary OD contains
47. 1:49the parameters defining a CAN open
48. 1:51node's behavior and is accessed via
49. 1:53SDOS's.
50. 1:56The SDO service allows for the reading
51. 1:58and modification of OD
52. 2:00entries while the PDIO service serves to
53. 2:03transmit real-time data
54. 2:06efficiently. The transmission methods
55. 2:08differ significantly with SDOS's being
56. 2:11more suitable for configuration tasks
57. 2:13and PDOS's being preferred for
58. 2:15operational data due to their minimal
59. 2:17overhead.
