The following table is an example of the word/bit definitions for an
8 in/8 out combination module.
The following table is an example of the word/bit definitions for an
8 in/8 out combination module that uses a 16 input expansion module.
The following table describes input and output bits used in both the example
tables above.
The PROFIBUS configuration tools require a GSD file in order to configure
the module’s parameters. The GSD file can be found at the Web site

Byte Bit Description
Produces 0-2 00-07 Input Status bits - when the bit is set (1), the input is on.
Bit 00 corresponds to input I0, bit 01 corresponds to
input I1, bit 02 corresponds to input I2, and so forth.
Consumes 0 00-07 Output bits - when the bit is set (1), the output will be
turned on. Bit 00 corresponds to output O0, bit 01
corresponds to output O1, bit 02 to output O2, and so
forth.
