Chapter 3 I/O Memory Mapping
Configuration Data File
The manipulation of the bits from this file is normally done with programming
software, such as RSLogix 500, RSLogix 5000, or RSNetWorx for DeviceNet,
during initial configuration of the system. In that case, graphical screens are
provided by the programmer to simplify configuration. However, some systems,
like the 1769-ADN DeviceNet adapter, also allow the bits to be altered as part of
the control program, using communication rungs. In that case, it is necessary to
understand the bit arrangement. The channel configuration words, words 0 and
1, are described on page 131. Refer to the Compact Analog I/O User Manual,
publication number 1769-UM002
for additional details.
