* ...Application Layer Notes...

51

*

52

* Application Layer Decoding based on information available in

53

* DNP3 Basic 4 Documentation Set, specifically the document:

54

* "DNP V3.00 Application Layer" v0.03 P009-0PD.APP & Technical Bulletins

55

*

56

* ---------------------------------------------------------------------------

57

*

58

* Several command codes were missing, causing the dissector to abort decoding

59

* on valid packets. Those commands have been added.

60

*

61

* The semantics of Variation 0 have been cleaned up. Variation 0 is the

62

* "Default Variation". It is used only in Master -> Slave read commands

63

* to request the data in whatever variation the Slave is configured to use by

64

* default. Decoder strings have been added to the Binary Output and

65

* Analog Output objects (10 and 40) so that group read commands will

66

* decode properly.
