1.1 Introduction

EtherNet/IP™ is the most commonly used industrial communication protocol managed by Open DeviceNet Vendors Association (ODVA). EtherNet/IP is an application layer protocol that is transferred inside a TCP/IP Packet. That means that EtherNet/IP is simply the way data is organized in a TCP or UDP packet. EtherNet/IP is part of CIP, the Common Industrial Protocol. CIP defines the Object structure and specifies the message transfer. CIP protocol over Ethernet is EtherNet/IP.

This document describes how to enable EtherNet/IP protocol support in Smart Wireless Gateway (Gateway). This document also explains the procedure to import Order Options, enable protocol

support, and establish various types of connections with Rockwell ControlLogix UCMM, and Class3 connections.

The document also explains about understanding different user interface pages within the Smart Wireless Gateway. These pages include, EtherNet/IP statistics, the communication page, and how to map device variables in the EtherNet/IP mapping page. It is assumed that there is general knowledge of how to establish connections using the Rockwell ControlLogix PLC. Consult the manual for the specific PLC. This document is just aimed at users looking to incorporate data values from the Smart Wireless Gateway. For assistance, contact your local wireless specialist.

1.3 Connecting to the ControlLogix PLC

This section assumes knowledge of Allen-Bradley software. The IO Module is configured with a valid IP address on the same subnet as the Gateway and the PC.

A basic knowledge of the Emerson Smart Wireless Gateway is required. The Gateway will need to be configured with a valid IP address on the same subnet as the Allen-Bradley control system and the PC.

The Emerson 1420 device uses multiple Class 1 CIP connections within a Generic Profile. The latest version of RSLogix5000 is required for you to use this capability. This requires V19 and higher of RSLogix5000. V20 of RSLogix5000 includes features that automatically populate parameters such as for input/output instances for the Generic CIP Module making some of the steps in this manual unnecessary.

Note

 The PLC processor has to be taken offline to be configured, then downloaded to accept

the EtherNet/IP setup. This means the protocol can't be implemented when the process is running.

 EtherNet/IP can only be implemented on ControlLogix processor firmware revision 17

and up.

Manual Supplement

00809-0500-4420, Rev BB

 EtherNet/IP will only work on the Ethernet 1 connection on the Gateway.

 When mapping data, only use one input “instance” and one output “instance”. An

Allen-Bradley Ethernet card can only handle one instance per setup in the PLC.

 EtherNet/IP can only be implemented on redundant ControlLogix processors starting

with firmware revision 20 and above.

 See “Other information” on page 36 for limitations with explicit messaging before

proceeding.

Section 1.3.2, 1.3.4, 1.3.5 and 1.3.6 detail connecting to the ControlLogix PLC using four separate methods, Class 1 Connections: CIP BUS Module, UCMM Connection, Class 3 Connections and Generic Gateway Module respectively. The methods are defined below. Use only one of these methods to connect to the PLC.

Class 1 Connections (I/O): CIP BUS Module - Establishes a periodic exchange of data between a scanner and an adapter. Messages are sent as connected messages which utilize resources within each node that are dedicated in advance to a particular purpose. The messaging is implicit and is time-critical in nature. Implicit messaging (or I/O) is typically used for real-time data exchange when speed and low latency is important. They include very little information about their meaning so its transmission is more efficient, but less flexible than explicit.

UCMM Connection (explicit messaging - unconnected) - Commands or data requests sent from the scanner to individual target nodes (Class 3 messages). Unconnected messaging is used during connection establishment and for infrequent, low-priority messages. The Unconnected Message Manager, or UCMM, refers to the unconnected resources in a device. Explicit messaging connections in general are request-response transactions between two nodes typically used for non-real time data, normally for information. They include a description of their meaning so the transmission is very flexible but less efficient.

Allen-Bradley Integration

Manual Supplement

00809-0500-4420, Rev BB

Class 3 Connection - Similar to UCMM connection Class 3 connection is used for individual request/response transactions. A request from a scanner always results in a response from the adapter indicating the success or failure of the request. Messaging is explicit and connected rather than unconnected.

Generic Gateway Module - Similar to CIP BUS Module the Generic Gateway Module is established to move application specific I/O data at regular intervals. The Generic Gateway Module however establishes class 1 connection to a single pair at a time whereas the Ethernet CIP BUS Method allows connection to multiple pairs.

For status and output capability, the use of the CIP Bus method is recommended. It should be noted that the CIP Bus method does require more memory than the generic Gateway method.

These are just examples of ways to bring in the data from the network. There are many possible configurations.

Note

For instructions on how to first establish a connection to the Gateway, see either the Quick Start Guide (document number 00825-0200-4420) or the Smart Wireless Gateway manual (document number 00809-0200-4420).

6. Write the appropriate value in the output tabs as shown. (In this case 1 is written to both mapped parameters.)

Note

Data is written properly only in online mode.

1.5 Troubleshooting

Problem Suggested solution

Unable to see the Gateway on rslinx as described, although the EDS file was successfully installed.

Manual Supplement

00809-0500-4420, Rev BB

We consider that the machine on which rslinx is installed is in the same subnet as the Gateway. We can explicitly add the Gateway IP address by choosing the AB_ETH-1 driver. See attached screenshots. Also screenshots for EDS file Installation (Allen-Bradley Integration Document are in the user manual already.

Unable to find where to allocate the 'reliability' float and the tools for 'online,' 'PV_healthy,' etc. How do I poll them? Is it a different class instance? (The manual only shows dint/int/real/sint).

Are the definitions for SYSTEM_DIAG.ADDITIONAL_STATUS shown anywhere for the predefined registers?

Do Predefined Registers hold last state if the instrument goes offline like the data does?

1.6 Other information

1. Only 124 members are allowed for mapping per pair.

In EtherNet/IP, Each Instance Pair can hold the data up to 496 bytes, but the user can only map a maximum of 124 members per instance pair. (Whatever may be the data type of mapped variables, for e.g. If user wants to map all Boolean variables in particular instance, maximum 124 Boolean variables they can map in the selected instance pair.) Some of the hosts support maximum 1500 bytes of data. Hence presently for device variable mapping chosen 3 instance pairs of size 496 bytes each.

Float = real, Booleans also can be mapped. You can map any variable which you can see on Explorer>Device Name>Published data web page and read in RsLogix with the datatype mentioned on web page.

Navigate to Explorer>Device name(e.g.wihartgw)>See Additional status tab.Let us know if you are looking for anything else by means of definition.

It will not hold the last state like other data, It will change according to the particular parameter status i.e good or bad. (Whatever Additional status is seen in the webpage, the same will appear in the RSLogix).

2. 32-bit error value, for the Point Name which does not exist or the Point Name which is having bad status while first time mapping.

While mapping of a particular variable for the first time, if mapped variable status is bad/offline, EtherNet/IP will treat that variable as 32 bit (Undefined Data). So as shown in communication page, it will show the error as 32 bit value. (Whatever may be the actual data type of mapped variable).

3. The user can map variables/Point Names of mix data types in any instance pair. (100-101, 102-103, 104-105) In this case it’s user’s responsibility to find a particular mapped variable value in RSLogix Class1 I/O Connection. Here depending on different data types (8, 16, 32 bit) user need to see mapped variable values in Class 1 Connection.

4. Rosemount 702 written data becomes zero after reestablishment of Class 1, Class 3

5. Currently in the application there are 3 pairs of assembly objects 100-101, 102-103,

6. Regarding Input Size 124:

Connections.

 EtherNet/IP uses producer consumer model. So on every RPI EtherNet/IP scanner

and adapter produces its own data for each other.

 In Rosemount 702 write case, whenever Class 1, Class3 connection

re-establishes, scanner will produce data with all zeros so Smart Wireless Gateway adapter will consume this data.

 In case of Class 1, Class 3 connection reestablishment, the previous written data

to Rosemount 702 devices will be zero (Here only those writable variable values become zero, which mapped to that particular instance). The user needs to record the Rosemount 702 written data before removing the particular connection and rewrite again.

104-105 (decimal) can be read. The mapped values from 101, 103 & 105 (in case of explicit messaging) can be read depending on the mapping done in webpage.

Size of assembly object is 496 bytes (fixed). When you are reading DINT or REAL (float values) which are of 4 bytes you have to read it as an array. For example, float values from the assembly object which is 496 bytes, so the size will be 124 or 496/4. If you want to read values as INT (2 bytes), the size will be 248, 496/2.

Note

Retaining old values vs. using “all zeros” on a new connection is “scanner specific” functionality, there are no rules in EtherNet/IP specs about this behavior.
