Digital I/O Operation
1715 Digital Module
Overview
The 1715 digital I/O modules are I/O modules that provide On/Off
detection and actuation. By using the producer/consumer network model,
digital I/O modules can produce information when needed while providing
additional system functions.
The 1715 digital I/O modules mount in a 1715 Redundant I/O System and
use an I/O termination assembly mounted in an I/O base unit to
communicate via redundant 1715 adapter modules.
Before you install and use your module, you must do the following:
• Install and ground a user-supplied, 24V DC power supply.
• Determine if you are using your digital I/O module in Simplex or Duplex
mode.
• Install the correct termination assembly based on your determination for
either simplex or duplex operation.
• Configure the project in RSLogix 5000 software or the Logix Designer
application to accept the number and type of modules for the project.
