Important Interface Considerations

Before you begin using your interface, note the following important
considerations.

ATTENTION: You must use firmware version 2 or later Guardmaster Safety
Relays equipped with the optical bus with the interface. Firmware version 1
Guardmaster Safety Relays do not work with the interface.

Rockwell Automation Publication 440R-UM009B-EN-P - February 2014 7

Chapter 1 About the Interface

About the Interface

The Guardmaster EtherNet/IP Network Interface provide connectivity to

EtherNet/IP networks for Guardmaster Safety Relays.

The interface is for the optical bus backplane that provides connectivity through

two RJ-45 connectors for 2-port pass-through support of daisy chain or ring, and

the existing star and tree network topologies.

Power Up a System

Each time the interface is powered up, the adapter compares the number of I/O

modules present on its backplane to the chassis size value from non-volatile

memory. The adapter does not allow any I/O connection until the number of

I/O modules present equals the chassis size value minus one for the adapter itself.

On power up, the interface assigns an address to every Guardmaster Safety Relay

(up to six) in the backplane. The addressing starts from left to right with the

Guardmaster Safety Relay to the immediate right of the interface taking the first

address of 1.

RIUP Situations

Interface Features

You must observe the following rules for Guardmaster Safety Relay system

construction and the

• Actual Guardmaster Safety Relay identification (such as, electronic
keying) is done when connection establishment requests are received from
the controller or controllers. The interface will not allow any I/O
connections until the number and type of Guardmaster Safety Relays
match the configuration in the connection request.

• A Guardmaster Safety Relay removed under power disrupts
communication of the other Guardmaster Safety Relays in the system.
Connections to all safety relays are disallowed until the entire system,
including the interface, is power cycled to initiate re-addressing the system.

• If safety relays of different types are removed and returned to the wrong
locations, attempts to connect to these safety relays will fail during
verification of the electronic ID (providing that keying has not been
disabled).

• If safety relays of the same type are removed and returned to the wrong
locations, they accept connections from the controller or controllers once
they pass their electronic keying check.

Features of the interface include:

• Use of EtherNet/IP messages encapsulated within standard TCP/UDP/
IP protocol

• Common application layer with ControlNet and DeviceNet networks

• Interfacing via Category 5 rated twisted pair cable

removal and reinsertion of safety relays.

Use of the Common Industrial Protocol (CIP)

Understand the Producer/ Consumer Model

The adapter uses the Common Industrial Protocol (CIP). CIP is the application
layer protocol specified for EtherNet/IP, the Ethernet Industrial Protocol, as well
as for ControlNet and DeviceNet networks. It is a message-based protocol that
implements a relative path to send a message from the producing device in a
system to the consuming devices.

The producing device contains the path information that steers the message
along the proper route to reach its consumers. Since the producing device holds
this information, other devices along the path simply pass this information; they
do not store it.

This has the following significant benefits:

• You do not need to configure routing tables in the bridging modules,
which greatly simplifies maintenance and module replacement.

• You maintain full control over the route taken by each message, which
enables you to select alternative paths for the same end device.

The CIP producer and consumer networking model replaces the old source and
destination (master and slave) model. The producer and consumer model reduces
network traffic and increases speed of transmission. In traditional I/O systems,
controllers poll input modules to obtain their input status. In the CIP system,
input modules are not polled by a controller. Instead, they produce (multicast or
unicast) their data either upon a change of state (COS) or periodically.

Multicast is the default mode for version 17 Logix and earlier controllers and
unicast is the default for version 18 with multicast as a selectable option.

The frequency of update depends upon the options chosen during configuration
and where on the network the input module resides. The input module,
therefore, is a producer of input data, and the controller is a consumer of the data.

The controller also produces data for other controllers to consume. The
produced and consumed data is accessible by multiple controllers and other
devices over the EtherNet/IP network. This data exchange conforms to the
producer and consumer model.

10 Rockwell Automation Publication 440R-UM009B-EN-P - February 2014

About the Interface Chapter 1

Specify the Requested Packet Interval (RPI)

Support of Data Connections

The Requested Packet Interval or RPI is the update rate specified for a particular
piece of data on the network. The RPI can be specified for the interface and
include all of the Guardmaster Safety Relays in the system.

When you add an interface to the I/O configuration of a controller, you must
enter the RPI as a parameter. This value specifies how often to produce the data
for that device. For example, if you specify an RPI of 50 ms, it means that every
50 ms the device should send its data to the controller and the controller should
send the consumed (output) data to the device.

Use RPIs only for devices that exchange data. For example, a ControlLogix
EtherNet/IP bridge module in the same chassis as the controller does not require
an RPI, because it is not a data-producing member of the system. Its use is only as
a bridge to remote racks.

TheGuardmaster EtherNet/IP Network Interface supports data connections.

A data connection to the interface is a grouping of data from one or more
Guardmaster Safety Relays into a single block of data sent over a single
connection at the same data rate.

Chapter 3

Configure the Interface for Your EtherNet/ IP Network

Overview

Before using your interface in an EtherNet/IP network, you need to configure it
with an IP address, subnet mask, and optional Gateway address. This chapter
describes these configuration requirements and the procedures for providing
them. Here are ways you can do this:

• Use the Rockwell BootP/DHCP utility, version 2.3 or later, that ships
with RSLogix 5000 or RSLinx software.

– You can also use this utility to reconfigure a device with an IP address

you must change.

• Use a

• Use the Network Address rotary switches.

• Have your network administrator configure the interface via the network

See the table for a list of where to find information in this chapter.

Configuration Requirements

Before you can use your interface, you must configure its IP address, its subnet
mask, and, optionally, a gateway address. You can use the Rockwell BootP utility,
version 2.3 or later, to perform the

configuration. You can also use a DHCP

server or the network address switches to configure these parameters.

ATTENTION: You must use firmware version 2 or later Guardmaster Safety
Relays equipped with the optical bus with the interface. Firmware version 1
Guardmaster Safety Relays do not work with the interface.

If you need to reset the interface to factory defaults, set the network address
rotary switches to 888 and perform a power cycle to the device.

IP Address

The IP address identifies each node on the IP network (or system of connected
networks). Each TCP/IP node on a network (including the interface) must have
a unique IP address.

The IP address is 32 bits long and has a Network ID part and Host ID part.
Networks are classified A, B, C, (or other). The class of the network determines
how an IP address is formatted

.

You can distinguish the class of the IP address from the first integer in its dotted­decimal IP address as follows:

Range of first integer Class Range of first integer Class

0 1…127 A 192…223 C

128…191 B 224… 255 other

Each node on the same physical network must have an IP address of the same
class and must have the same network ID. Each node on the same network must
have a different Host ID thus giving it a unique IP address.

IP addresses are written as four decimal integers (0…255) separated by periods
where each integer gives the value of one byte of the IP address

For example, the 32-bit IP address:

10000000 00000001 00000000 00000001 is written as

128.1.0.1
