Output Parameters

This communication driver supports importing custom data types defined in the controller project.

NOTE: The driver supports Logix firmware versions v20, v24, v28 and higher. However, not all controllers and controller families are supported on all versions of Logix.

NOTE:

5560 Redundancy v20 supports IP Address Swapping only.

5570 Redundancy v20 and greater supports IP Address Swapping only.

5580 Redundancy v33 and greater supports IP Address Swapping only.

Controller variables

The

Controller

category in the Dynamic Link browser displays the variables related to the Rockwell Automation EtherNet/IP driver. Bind these variables to objects in your project to display controller status information.

Controller variables
Variable	Type	Definition	Read/Write	Restart Required
Active data items	UInt32	Number of active data items that are being read from the controller	Read-only	Restart not required
Activity counter	UInt32	Number of communication packets received from the controller	Read-only	Restart not required
Catalog number	String	Catalog number read from the controller	Read-only	Restart not required
Controller name	String	Name of the controller	Read-only	Restart not required
Failed data items	UInt32	Number of active data items that currently could not be read from the controller	Read-only	Restart not required
Major rev	UInt32	Major version of the controller firmware	Read-only	Restart not required
Minor rev	UInt32	Minor version of the controller firmware	Read-only	Restart not required
Mode	String	Operating mode of the controller. The modes are Run, Program, Fault, Remote Run, and Remote Program.	Read-only	Restart not required
Optimized blocks	UInt32	Number of optimized data blocks sent between the controller and the HMI device	Read-only	Restart not required
Path	String	Communication path to the controller	Read-only	Restart not required
Present	Boolean	Indicates if the controller is on the network	Read-only	Restart not required
Product code	UInt32	Product code read from the controller	Read-only	Restart not required
Product type	UInt32	Product type read from the controller	Read-only	Restart not required
Recoverable major faults	Boolean	Indicates if the controller has detected a recoverable major fault	Read-only	Restart not required
Recoverable minor faults	Boolean	Indicates if the controller has detected a recoverable minor fault	Read-only	Restart not required
Run mode	Boolean	Indicates if the controller is in run mode	Read-only	Restart not required
Synchronized	Boolean	Indicates if the data in the controller is synchronized with the data in the runtime application	Read-only	Restart not required
Synchronization state	String	Synchronization status of the controller	Read-only	Restart not required
Unrecoverable major faults	Boolean	Indicates that the controller has detected an unrecoverable major fault	Read-only	Restart not required
Unrecoverable minor faults	Boolean	Indicates that the controller has detected an unrecoverable minor fault	Read-only	Restart not required
Vendor	UInt32	Vendor code read from the controller	Read-only	Restart not required

Communication

To establish communication with a Logix controller, specify the

Route

property of the corresponding

Station

object in the following format

IP_Address\Backplane\Chassis_Slot_Number

The 1756-CMEE Embedded Edge Compute Module supports the following format

\Backplane\Chassis_Slot_Number

to access the controller tags directly from the backplane, without the EtherNet/IP connectivity.

To configure routing that involves multiple Logix controllers, use the following format

IP_Address\Backplane\Port\Address\BackplaneChassis_Slot_Number

. If needed, repeat the

Port\Address

part.

TIP: Use

FactoryTalk® Linx™

to browse the network and determine the

Route

value.

In the following example, the

OptixPanel™

reads tags from the Logix rack 2 CPU and the

Route

property of the

Station

object has the following value

192.168.1.10\Backplane\2\A\192.168.2.3\Backplane\0

Accessing a controller on a different network through the backplane

Ethernet communication modules support

You cannot use the 1756-ENET EtherNet/IP Bridge Module with the
