Configuration Data File

The manipulation of the bits from this file is normally done with programming software (for
example, RSLogix 5000 or RSNetWorx for DeviceNet software) 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.
