Software Configurable
You use the Logix Designer application to configure the module, monitor
system operation, and troubleshoot issues. You can also use the Logix Designer
application to retrieve the following information from any module in the
system:
• Serial number
• Firmware revision information
• Product code
•Vendor
• Error and fault information
• Diagnostic information
By minimizing the need for tasks, such as setting hardware switches and
jumpers, the software makes module configuration easier and more reliable.
Requested Packet Interval
The Requested Packet Interval (RPI) is a configurable parameter that defines a
specific rate at which data is exchanged between the owner-controller and the
module.
You set the RPI value during initial module configuration and can adjust it as
necessary after module operation has begun.
For more information on guidelines for specifying RPI rates, see the
Logix 5000™ Controllers Design Considerations Reference Manual,
publication 1756-RM094
.
IMPORTANT If you change the RPI while the project is online, the connection to the
module is closed and reopened in one of the following ways:
• You inhibit the connection to the module, change the RPI value, and
uninhibit the connection.
• You change the RPI value. In this case, the connection is closed and
reopened immediately after you apply the change to the module
configuration.
