Configuring Channel Properties: The EtherNet/IP page

The EtherNet/IP Page

Use the EtherNet/IP page of the Channel Properties window to configure:

properties that determine how the EtherNet/IP communication module, in its role as an I/O scanner, opens both implicit and explicit connections
the frequency for transmitting produced data over implicit connections
the timeout period for explicit connections
the behavior of the module, in its role as an I/O scanner, when:
- the application is stopped, or
- the EtherNet/IP module receives a reset service request

NOTE: This page is displayed only when you are using . Advanced mode properties are indicated by the

icon.

To turn on Advanced Mode, select: File → Preferences → Advanced

NOTE: Refer to the topic Configuring Properties in the Devices Window for information on how to display property descriptions and edit property values.

Configuring EtherNet/IP Properties

Note: Only an experienced developer of EtherNet/IP networks should edit any of the following read-write properties.

Name	Description
Timeout
FW_Open IO Connection Timing	The amount of time the EtherNet/IP module waits for the Forward_Open IO messaging transaction to open an implicit messaging connection. Default = 5000 ms
FW_Open EM Connection Timing	The amount of time the EtherNet/IP module waits for the Forward_Open IO messaging transaction to open an explicit messaging connection. Default = 3000 ms
EM Connected RPI	The value used to set the T->O (target to originator) and O->T (originator to target) requested packet interval (RPI) for all explicit message connections. This value is used to calculate the lifetime of a connection. Default = 10000 ms.
EM Request Timeout	The amount of time the EtherNet/IP module waits between a request and reply of an explicit message. Default =10 s.
Output
STOP Behavior	The state of the EtherNet/IP module when the CPU application goes into a STOP state: TRUE indicates that the module enters STOP state (implicit connections are closed). FALSE indicates that the module enters IDLE state (implicit connections are not closed). Default = FALSE
Allow Reset Explicit Message	The behavior of the EtherNet/IP module—as I/O scanner—when it receives a reset service request: TRUE indicates the module resets itself. FALSE indicates the module ignores the reset service request and continues uninterrupted operations. Default = FALSE
