Configuration File
The read/writable configuration data file allows the setup of the digital filter settings
for each of the two input groups. Group 0 is inputs 0…7, Group 1 is inputs 8…15.
The manipulation of the bits from this file is normally done with programming
software (for example, RSLogix 500 or RSNetworx for DeviceNet software) during
initial configuration of the system. In that case, graphical screens are provided via
the programmer to simplify configuration. However, some systems (for example,
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.
