Chapter 3 I/O Memory Mapping
Configuration Data File
The manipulation of 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 provided
by the programming software simplify configuration.
Some systems, like the 1769-ADN DeviceNet adapter system, 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.
