RA EtherNet/IP Driver

The
RA EtherNet/IP Driver
 supports importing tags in the online and offline modes.

Controller tags

The Logix Driver supports both
L5X
 and
ACD
 file formats for importing tags in the offline mode. The file format of exported tags depends on the controller. Refer to the
Logix 5000™ Controllers Import/Export Reference Manual
, publication
1756-RM014A
.
For every
Add-On Instruction
, a structure containing the local data is created. An imported structure is associated with a dynamic link of
Input/Output
 type. You can manage the
Add-On Instruction
 function blocks as if they were a user-declared data type.
IMPORTANT: It is the designer responsibility to set the necessary restrictions on the controls to which they attach the members that are declared in
ADD-ON
 as
Read Only
 or
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.

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
\Backplane
Chassis_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
RA EtherNet/IP Driver
.
