Chapter 3 Digital I/O Operation
Module Fault Reporting
1715 digital I/O modules provide hardware and software indication when a
module fault has occurred. Each module’s status indicator, as well as the Logix
Designer application, graphically displays this fault and includes a fault message
describing the nature of the fault. This feature lets you to determine how your
module has been affected and what action must be taken to resume normal
operation.
Fully Software Configurable
The Studio 5000 Logix Designer application uses a custom, easily understood
interface to write configuration. All module features are enabled or disabled
through the I/O configuration portion of the software. You can also use the
software to interrogate any module in the system to retrieve the following:
• Vendor
• Product Type
• Product Code
• Revision
• Serial Number
• Product Name
By eliminating such tasks as setting hardware switches and jumpers, the software
makes module configuration easier and more reliable.
Module Inhibiting
Module inhibiting lets you indefinitely suspend a connection between an owner-
controller and a digital I/O module without having to remove the module from
the configuration. This process lets you temporarily disable communication to a
module, such as to perform maintenance. You can do this in the following ways:
• You write configuration for an I/O module but inhibit the module to
prevent it from communicating with the owner-controller. In this case, the
owner does not establish a connection and configuration is not sent to the
module until the connection is uninhibited.
