Byte Description
46, 47
14, 15
Module setup, a bitmapped word
bit 0 indicates whether defaults are defined in the configuration
structure. If this bit is ‘1’, then input segments mode, output
segments mode, default input values, and default output values
fields are included below.
Bit 1 enables fault reporting for the module. bits 2-15 are reserved
and must be set to zero.
48, 49
16, 17
Reserved (must be 00)
50, 51
18, 19
Length in bytes of module-specific data
52, 53
20, 21
Reserved (must be 00)
54, 55
22, 23
Reserved (must be 00)
Optional I/O configuration fields
56,… N
Input segments list, an eight-byte reference description field for
each discrete or analog input segment, see below.
Output segments list, an eight-byte reference description field for
each discrete or analog output segment.
Input segments mode, a bitmapped word with a bit representing
each reference description in the input segments list. If the bit is
‘1’, then inputs hold the last state. If the bit is ‘0’, then the input's
default values are in the default input values field below.
Output segments mode, a bitmapped word with a bit
representing each reference description in the output segments
list. If the bit is
‘1’, then outputs hold the last state. If the bit is ‘0’, then the
outputs default to values in the default output values field below.
Default input values (one byte for each byte of inputs defined for
the module)
Default output values (one byte for each byte of outputs defined
for the module)
Module-specific data
Context-dependent data fields
Pad bytes (must be 00) round the bytes in the record up to the
next larger multiple of 26.
