overall control system because, while the module is being removed or inserted,
there is no additional disruption to the rest of the controlled process.
Module Fault Reporting
1715 digital I/O modules provide hardware and software indication when a
module fault has occurred. The status indicator of each module, and the Logix
Designer application, graphically displays this fault and includes a fault
message describing the nature of the fault. This feature lets you 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.
• In your application, a controller already owns a module, has downloaded
configuration to the module, and is 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.
