Identifier-Related Diagnostics:

For each identifier byte assigned during configuration (for example, 0 x 10 for 1 byte input), a bit is reserved.

In the case of a modular system with an identifier byte each per module, module-specific diagnostics can be indicated. One bit respectively will then indicate diagnostics per module.

	Bit 7	Bit 6	Bit 5-0
Header Byte	0	1	Block length in bytes including header
Bit Structure	1				1
	Identifier Byte 7 has			etc.	Identifier Byte 0 has
		diagnostics			diagnostics

Channel-Related Diagnostics:

In this block, the diagnosed channels and the diagnostics cause are entered in sequence. Three bits are required per entry.

	Bit 7	Bit 6	Bit 5	Bit 4 - 0
Header Byte	1	0	Identification Number
Channel Number	Coding		Channel Number
	Input/Output
Type of Diagnostics	Coding			Coding
	Channel Type			Error Type

Coding of the error type is in part manufacturer-specific; other codings are specified in the Standard.

Example:

0	0	0	0	0	1	0	0	Device-related diagnostics.
Device-specific								Meaning of the bits
diagnostics field of								is specified
length 3								manufacturer-specific.
0	1	0	0	0	1	0	1	Identifier-related diagnostics.
							1	Identification number 0 has diagnostics.
			1
						1		Identification number 18 has diagnostics.
								Channel-related diagnostics, identification number 0.

1	0	0	0	0	0	0	0
0	0	0	0	0	0	1	0	Channel 2.
0	0	0	1	0	1	0	0	Overload, channel organized bit by bit.
1	0	0	0	1	1	0	0	Channel-related diagnostics identification number 12.
0	0	0	0	0	1	1	0	Channel 6.
1	0	1	0	0	1	1	1	Upper limit evalue xceeded, channel organized word by word.

Status

If the Bit EXT_DIAG is set to 0 , data is viewed as status info from the system view. f.e. cancellation of the error triggering the diagnostics.
