6.9.4 Identification-specific diagnostic data
The identification-specific diagnostics indicates where (in which module) the error occurred.
Byte 41, identification-specific diagnostic header
Bit 0 The length in bytes of the identification-specific diagnostics
Bit 1 The length in bytes of the identification-specific diagnostics
Bit 2 The length in bytes of the identification-specific diagnostics
Bit 3 The length in bytes of the identification-specific diagnostics
Bit 4 The length in bytes of the identification-specific diagnostics
Bit 5 The length in bytes of the identification-specific diagnostics
Bit 6 The code for identification-specific diagnostics is always equal to 0.
Bit 7 The code for identification-specific diagnostics is always equal to 1.
Byte 42, details of the module where the errors occurred, modules 1-8 (including gateway I/O)
Bit 0 1 = error in gateway I/O
Bit 1 1 = error in extension I/O at position 1
Bit 2 1 = error in extension I/O at position 2

Bit 4 1 = error in extension I/O at position 4
Bit 5 1 = error in extension I/O at position 5
Bit 6 1 = error in extension I/O at position 6
Bit 7 1 = error in extension I/O at position 7
Byte 43, details of the module where the errors occurred, modules 9-16
Bit 0 8 = error in extension I/O at position 8
Bit 1 9 = error in extension I/O at position 9
Bit 2 10 = error in extension I/O at position 10
Bit 3 11 = error in extension I/O at position 11
Bit 4 12 = error in extension I/O at position 12
Bit 5 13 = error in extension I/O at position 13
Bit 6 14 = error in extension I/O at position 14
