Chapter 3 I/O Memory Mapping
1769-IF16V The following I/O memory mapping lets you configure the 1769-IF16V module.
Input Data File
For each module, slot
x, words 0…15 in the input data file contain the converted
value of the module’s analog input channels. Word 16 in the input data file
contains the time stamp value, if time stamping is enabled, that corresponds to
the module's last input data sampling period. Words 17…21 in the input data file
contain status bits for the analog input channels.
