I/O Memory Mapping Chapter 3
Configuration File
For each input module, slot x, words 0 and 1 in the configuration file control the
amount of filtering applied to the signals from the field input points. The amount
of filtering applied can be configured individually for both the On-to-Off and
Off-to-On edges of each isolated group of input signals.
1769-IQ6XOW4
The following I/O memory mapping lets you configure the 1769-IQ6XOW4
module.
Input Data File
For the inputs on this module, slot x, word 0 in the input data file contains the
current state of the field input points. For the 1769-IQ6XOW4, bits 6 to 15 are
not used.
For the outputs on this module, slot x, input data file word 1 contains the state of
the module’s output data (output data echo) file word 0. During normal
operation, these input bits represent the logic state that the outputs are directed
to by the control program. They are also dependent upon these configurations:
• Program Mode configuration, if supported by the controller
• Fault Mode configuration, if supported by the controller
For the 1769-IQ6XOW4, bits 4 to 15 are not used.
