Chapter 8 EtherNet/IP Network
Requested Packet Interval
The Requested Packet Interval (RPI) is a configurable parameter that defines a rate at which
the owner-controller and the module exchange data. You set the RPI value during initial
module configuration and can adjust it as necessary after module operation has begun.
Type Definition in Module Dialog
The Type in the module creation defines the type of devices to be connected. There are five
types to choose from:
• Generic Device is for all EtherNet/IP devices that do not have supported predefined
data structures in the Micro800 controller.
• PowerFlex 523-E2P or PowerFlex 525-E2P are for PowerFlex 520-series drives that use
the dual-port Ethernet plug-in communication card.
• PowerFlex 525-EENET is for PowerFlex 525 drives that use the embedded Ethernet port.
• Kinetix 5100 is for all Kinetix 5100 servo drives. When this option is selected, a new field
that is called Catalog is shown where you must select the correct Kinetix 5100 catalog
number.
Table 16 - Module Keying Options
Keying Option
Description
Compatible Module
Lets the installed device accept the key of the device that is defined in the project
when the installed device can emulate the defined device. With Compatible Module,
you can typically replace a device with another device that has the following
characteristics:
• Same catalog number
• Same or higher Major Revision
• Minor Revision as follows:
– If the Major Revision is the same, the Minor Revision must be the same or higher.
– If the Major Revision is higher, the Minor Revision can be any number.
Disable Keying
Indicates that the keying attributes are not considered when attempting to
communicate with a device. With Disable Keying, communication can occur with a
device other than the type specified in the project.
ATTENTION:
Be cautious when using Disable Keying; if used incorrectly, this option
can lead to personal injury or death, property damage, or economic loss.
We
strongly recommend
that you
do not use
Disable Keying.
If you use Disable Keying, you must take full responsibility for understanding whether
the device being used can fulfill the functional requirements of the application.
IMPORTANT:
Do not use this option in Safety applications.
Exact Match
Indicates that all keying attributes must match to establish communication. If any
attribute does not match precisely, communication with the device does not occur.
IMPORTANT
You can change the RPI while the project is online. If you change the RPI
while the project is online, however, 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.
