The ENB_CLX object represents the physical Allen-Bradley EtherNet/IP Communications module within a ControlLogix chassis.

The ENB_CLX object is hosted by CIP.

Note: A maximum of 65535 ENB_CLX objects can be created for the Communication Driver.

Add ENB_CLX objects to your ABCIP hierarchy

Select and right-click on the New_PORT_CIP_000 object.
Select Add ENB_CLX Connection from the shortcut menu. A New_ENB_CLX_000 object is created.
Rename the newly created object as appropriate. The ENB_CLX Parameters configuration view is displayed.

This configuration view has three parameters, two of which are configurable:

Module Type: Information provided automatically by the OI Server Manager (Ethernet Comm).
Host Name: Host Name or IP Address of the destination 1756-ENET/ENBT/EN2T/EWEB module.
- The Host Name is defined in the system Host file, usually found in: \Windows\system32\drivers\etc\hosts folder.
- Type in the network address where the PLC is located (for example, "10.11.12.13") or type in a host name if one is defined in the LocalHost list. The number of characters cannot be more than 255. The field cannot be blank.
  
  Note: The Host Name defaults to the LocalHost. If the LocalHost is selected and deleted, resulting in a blank Host Name box, and you apply the changes, this will result in an error message.
  
  Important: If setting up a SoftLogix or GuardLogix device, the host or IP address of the corresponding SoftLogix or physical GuardLogix device must be entered in the Ethernet/IP Bridge Module (ENB) node within the ABCIP Communication Driver hierarchy to establish communications with the device. For more information, see SoftLogix 5800 controllers or GuardLogix controllers.
Connection Timeout: Time (in milliseconds) allowed for establishing a socket connection to a target device.
- The valid range is 10 - 10000 milliseconds.
- The default value is 2000.
- The connection timeout is used if the object is underneath PORT_CIP.
