Allen-Bradley ControlLogix Ethernet Driver Help

24

It is important to verify communications with the proper controller. In the example above, if 10 was entered as the ControlNet Node ID in the ControlNet Gateway Device ID, communications will take place with Node 12 (octal equivalent of 10 decimal), not Node 10 (octal). If Node 12 (octal) does not exist, then the CNB module will return DF1 STS 0x02. This means that the link layer could not guarantee delivery of the packet. In short, the ControlNet Node could not be located on the ControlNet network.

Note 1: For more information on supplementing a Device ID with a routing path to remote ControlNet node, refer to Communications Routing.

Note 2: For more information on communications parameters, refer to ENI DF1/DH+/ControlNet Gateway Communications Parameters.

EtherNet/IP Gateway Setup

EtherNet/IP Gateway provides a means of communicating with MicroLogix, SLC 500, and PLC-5 series PLC on EtherNet/IP with the Allen-Bradley ControlLogix Ethernet Driver.

Requirements

2 or more Ethernet/IP Interface modules (such as 1756-ENBT). MicroLogix, SLC500, or PLC-5 series PLC with EtherNet/IP connectivity.

Note: EtherNetIP Gateway models do not support automatic tag database generation.

EtherNet/IP Gateway Device ID

The Device ID specifies the local device IP address as well as the remote EtherNet/IP address necessary for making a connection. Device IDs are specified as the following:

<IP or Hostname>,1,[<Optional Routing Path>],<ENBT Slot>.<ENBT Channel>.<Remote IP>

Designator Type*

Description

N/A

IP Address or host name of the local EtherNet/IP interface module.

Port ID

Port to backplane.

Multiple Link, Port pairs

Specifies a way out of the EtherNet/IP interface module and must equal 1 (port

to the back plane).

Link Address

The slot number of the second EtherNet/IP interface module.

Port ID Link Address

The EtherNet/IP port to use. The remote IP address of the target PLC.

*For more information, refer to Connection Path Specification.

Example 123.123.123.123,1,2.A.192.168.1.10

This equates to a local IP of 123.123.123.123. The second EtherNet/IP card resides in slot 2: use port A and addressing target device with IP 192.168.1.10.

Note 1: For information on supplementing a Device ID with a routing path to a remote EtherNet/IP device, refer to Communications Routing.

Note 2: For more information on communications parameters, refer to ENI DF1/DH+/ControlNet Gateway Communications Parameters.

Note 3: When configuring the Device ID, users should verify that the device can be detected using the same route through RSLinx.

Serial Gateway Setup

Serial Gateway provides a means of communicating with ControlLogix, CompactLogix, FlexLogix, and SoftLogix PLCs on a serial network with the Allen-Bradley ControlLogix Ethernet Driver.
