Using 1715 Analog I/O Module Features Chapter 4
Fully Software Configurable
The 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:
• 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.
The keying options available with your 1715 analog I/O are outlined in
Appendix B .
Status Indicator Information
Each 1715 analog I/O module has status indicators on the front of the module
that allow you to check the module health and operational status of a module.
Module Inhibiting
Module inhibiting lets you indefinitely suspend a connection between an owner-
controller and an analog I/O module. This process can occur in either of these
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.
• In your application, a controller already owns a module, has downloaded
configuration to the module and is currently exchanging data over the
connection between the devices. In this case, you can inhibit the module
and the owner-controller behaves as if the connection to the module does
not exist.
IMPORTANT Whenever you inhibit an output module, it enters the Program mode and
all outputs change to the state configured for the Program mode. For
example, if an output module is configured so that the state of the outputs
go to zero (0) during Program mode, whenever that module is inhibited,
the outputs goes to zero (0).
