18 CompactBlock I/O for DeviceNet Modules Series D
Publication 1791D-IN003A-EN-P - June 2003
The table below is an example of the word/bit definitions for an 8 in/
8 out combination module that uses a 16 input expansion module.
The table below describes input and output bits used in both of the
example tables above.
The DeviceNet Network uses advanced network technology,
producer/consumer communication, to increase network

Produces 1 I15 I14 I13 I12 I11 I10 I9 I8
Produces 2 I23 I22 I21 I20 I19 I18 I17 I16
Produces 3 ES Reserved
Consumes 0 O7 O6 O5 O4 O3 O2 O1 O0
ES = Expansion Status
Byte Bit Description
Produces 0-2 O0-O7 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.
Produces 3 O7 If Expansion Status (ES) bit is set, the expansion module is not
functioning properly or missing.
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.
