1769-IF4XOF2 Input Image
The input image file represents input channel data words I/O, channel
status bits. Input words 0 through 3 contain the converted analog
input data from the field device. Word 4, bits 0 to 3 are the over-range
flag bits for input channels 0 to 3. Word 5, bit 0 and 1 are the
over-range flag bits for channels 0 and 1. Words 6 and 7, bits 7
through 14 are the data echo. These words provide output
loopback/data echo through the input array. The Input Data File is
explained in more detail on page 4-3. To receive valid status
information, the channel must be enabled.
For example, to obtain the over-range status of input channel 2 of the
1769-IF4XOF2 analog module located in slot 3, use address I:3.4/2.
TIP
You can access information in the input image file
using the programming software configuration
screen.
TIP
The end cap does not use a slot address.
