I/O Memory Mapping Chapter 3
1769-IQ16F
The following I/O memory mapping lets you configure the 1769-IQ16F module.
Input Data File
For each input module, slot x, word 0 in the input data file contains the current
state of the field input points.
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, such as RSLogix 500, RSLogix 5000, or RSNetWorx for DeviceNet,
during initial configuration of the system. In that case, graphical screens are
provided via 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.
