How Communication Takes Place and I/O Image Table Mapping
1769-IF4 (Series A and B)
Analog Current/Voltage
Input Module (4 Channel)
Input Data
For each 1769-IF4 input module, input data words 0-3 contain the
analog value of the inputs. Word 4 and 5 contain analog status and
error information.
1769-IM12 240V AC Input
Module (12 Point)
Input Data
For each 1769-IM12 input module, input data word 0 contains the
current state of the field input points. Bits 12 to 15 are not used.
1769-IQ16 24V DC
Sink/Source Input Module
(16 Point)
Input Data
For each 1769-IQ16 input module, input data word 0 contains the
current state of the field input points.

SGN= sign bit in two’s format
Sx = general status bit for channels 0 through 3. This bit is set (1) when an error (over- or
under-range) exists for that channel.
Ux = under-range flag bits for channels 0 through 3. These bits can be used in the control
program for error detection.
Ox = over-range flag bits for channels 0 through 3. These bits can be used in the control
program for error detection.
