I/O Configuration for Discrete Input Modules
Overview This section provides information on configuration of 16-, 24-, 32-, and 96-point input
modules.
16-Point Input
Modules
The 16-point input modules are:
z 140DAI34000 (AC Input 24 Vac 16x1)
z 140DAI44000 (AC Input 48 Vac 16x1)
z 140DAI54000 (AC Input 115 Vac 16x1)
z 140DAI54300 (AC Input 115 Vac 8x2)
z 140DAI74000 (AC Input 230 Vac 16x1)
z 140DDI84100 (DC Input 10 ... 60 Vdc 8x2 Sink)
I/O Map Register
Assignment
The input modules listed above can be configured as either 16 contiguous 1x
references or as one 3x register.The following figure shows the 16-point register.
I/O Map Status
Byte
There is no I/O map status byte associated with these modules.

Zoom Selections
Push <Enter> to display and select the input type. This selection appears if the
module is I/O mapped to a 3x register. The following figure shows the input type
display.
24-Point Input
Module
There is only one 24-point input module: 140 DDI 673 00 (DC Input 125 VDC 3x8
Sink).
I/O Map Register
Assignment
The input module listed above can be configured as either 24 contiguous discrete
input (1x) reference, or as two contiguous input (3x) registers in the following format.
The following figures show the input point for Register 1 and Register 2.
