How Communication Takes Place and I/O Image Table Mapping 2-5

The following sections, as referenced above, give the input and

output data definitions for each Compact I/O module type. Their

mapping into the adapter’s input and output images are dependent on

their slot number and configured input and output sizes (as defined in

the I/O Structure section on page 2-1).

1769-IA8I Individually

Isolated 120V AC Input

Module (8 Point)

Input Data

For each 1769-IA8I input module, input data word 0 contains the

current state of the field input points. Bits 8 to 15 are not used.

1769-IA16 120V ac Input

Module (16 Point)

Input Data

For each 1769-IA16 input module, input data word 0 contains the

current state of the field input points.

1769-OW8 AC/DC Relay Output Module (8 Point) 2-13

1769-OW8I Individually Isolated AC/DC Relay Output Module (8 Point) 2-14

1769-OW16 AC/DC Relay Output Module (16 Point) 2-15

1769-IQ6XOW4 24V DC Sink/Source Input AC/DC Relay Output Module (6 Point In, 4 Point Out) 2-16

1769-IT6 Thermocouple/mV Input Module 2-17

1769-IR6 RTD/Resistance Input Module 2-18

1769-IF4XOF2 Combination Analog Module 2-19

1769-HSC High-Speed Counter Module 2-21

Module Description For I/O data
