Chapter 3 I/O Memory Mapping
1769-IG16
The following I/O memory mapping lets you configure the 1769-IG16 module.
Input Data File
For each module, slot x, word 0 in the input data file contains the state of the
module’s input points. The module implements inverted logic on the TTL
inputs. A logix low-input voltage results in the corresponding Input Data File bit
being set to 1. A logic high-input voltage results in the corresponding bit being
cleared to 0.
