tag for the channel is set to a value of 0.
Safety valid The safety circuit receives input signals that satisfy its requirements to allow
transition to an operational state.
Tap
A tap connects a safety device to the GuardLink circuit. GuardLink-enabled taps are
nodes on the GuardLink circuit. Passive taps are not GuardLink-enabled and therefore
must connect to a GuardLink-enabled device to be considered as a node on the
GuardLink circuit. A tap is not considered as a node when the tap is a passive or
passive power tap with a shorting plug.

Introduction
Overview A GuardLink® system is a collection of components to simplify a series
connection of safety devices while achieving the highest industrial safety
rating. The system has these important features:
• Simplifies the connection of series connected safety devices.
• Facilitates the scalability of the safety series connections.
• Provides diagnostic information about each device in the system without
having to run a separate status wire back to the machine control system.
• Allows the simultaneous or individual lock and unlock of guard locking
interlocks in the series connected system. No need for an additional wire
from the machine control system to lock and unlock the safety gate.
• Helps ease communication to the machine control system over
EtherNet/IP™. Communication includes sending non-safety commands
to devices and receiving status information back from the safety devices.
Figure 1 shows a typical safety system that uses the 432ES-IG3 network
interface module. A typical system consists of an HMI, a GuardLogix®
controller, the 432ES-IG3 GuardLink EtherNet/IP network interface module,
and a series connection of safety devices, which connect to the interface
through taps in a trunk and drop network configuration.
The GuardLogix controller and PanelView™ reside in an environmentally
protected control cabinet. The 432ES network interface module and associated
taps and devices are at various points on the machine.
Figure 1 - Typical 432ES-IG3 Network Interface Module Safety System
432ES-IG3 network interface module can control up to three safety zones, one
zone for each GuardLink channel. With logic, the channels can combine to
control only one or two zones.

Chapter 1 Introduction
Requirements
A GuardLogix controller must control the 432ES-IG3 network interface
module. See the publication 1756-SG001. As of the time of release, you can use
the following controllers:
• 1756 GuardLogix 5580 controllers
• 5069 Compact GuardLogix 5370 controllers
The controller must run Studio 5000® version 34.01 or later. You must use
FactoryTalk® Linx 6.30 or later for communications. A PanelView 5000 HMI is
required for automatic diagnostic reporting.
The 432ES-IG3 network interface module provides additional status
information and the ability to upgrade the firmware in GuardLink-enabled
devices. To achieve this functionality, the firmware in the taps and guard
locking switch is upgraded to 2.00x. The 432ES-IG3 network interface module
can operate with firmware 1.00x, but 2.00x is the preferred level. When
multiple levels of protocol connect on a channel, the channel operates at the
lowest level.
Automatic Diagnostics
Automatic diagnostics is a system-level feature in devices that provides device
diagnostics to HMIs and other clients, with zero programming. GuardLink 2.0
products come with the automatic diagnostics feature enabled by default, so
diagnostics - including device description conditions and state events - are
sent to an HMI device.
You can deactivate and activate the whole feature while online or offline from

Chapter 1 Introduction
Modes of Operation
The GuardLink system has four modes of operation for each channel:
• Start Up - Initializes the system when power is initially applied. The
432ES network interface module determines the number of channels in
use, and the number and type of nodes on each channel.
• Operational - All safety devices on the GuardLink channel are
safety-valid.
• Safe State - One or more of the devices on the GuardLink channel are not
safety-valid.
• Firmware Update - The 432ES network interface module or one of its
client devices is undergoing a firmware update. Updates can only occur
when the system is in the safe state.
The 432ES network interface module has three independent channels. Any
channel can be in the operational state, while the others can be in a safe state.
The 432ES-IG3 network interface module has one safety-rated controller
Status tag for each channel.
In the operational state, the 432ES network interface module transmits the
channel Status = 1 to the safety controller, which indicates the channel is in an
operating state. The machine must use the Status tag as part of the safety
function to allow the machine to enter Run mode.
In the safe state, the 432ES network interface module transmits the channel
Status = 0 to the safety controller, which indicates the channel is operating in a
safe state; one or more safety devices are actuated (not valid).
System Design GuardLink Components
Each GuardLink circuit accommodates up to 32 taps.
A typical GuardLink system consists of:
• One GuardLink interface
• One tap for each safety device
• One terminator for each GuardLink circuit
• Patchcords and cordsets
Taps Taps create nodes in the GuardLink circuit. A safety device connects to each
tap. The following types of taps are available:
• GuardLink-enabled taps that interface with devices that have
voltage-free safety contacts
• GuardLink-enabled taps that interface with devices that have OSSD
signals
• GuardLink-enabled 8-pin taps can be either Power to Release or Power to
Lock
• Passive taps that interface with devices that are GuardLink-enabled
• Passive power taps that interface with devices that are
GuardLink-enabled and add power to the link
GuardLink-enabled taps are available in an 8-pin and 5-pin device connection
version. Passive style taps are only available in a 5-pin device connection
version.

14 Rockwell Automation Publication 432ES-UM001A-EN-P - September 2022
Chapter 1 Introduction
The taps are intended to mount on the machine, near the location of the device
the tap monitors. You can mix and connect the different tap types and versions
in any order.
Tap Connections
Figure 3 identifies the tap connections. Follow the instructions to modify the
GuardLink circuit. The Link In (J1) connection supplies power to the tap.
Figure 3 - Tap Connections
Tap Cabling
The GuardLink system is designed to minimize wiring with quick-disconnect
patchcords, while also allowing some manual wiring to terminals, when
pin-out incompatibilities exist.
The preferred cables are the Bulletin 889D hardware (red jacket, PVC,
unshielded, with epoxy coat). Use any jacket color, however, the red is the
preferred color to indicate a safety circuit. To minimize the voltage drop due to
wire resistance, the preferred wiring gauge for the link cable is 18 AWG
(0.823 mm).

and-patchcords.html for other options, such as right-angle connectors,
stainless-steel couplings, and shielded cables.
Tap Type Description
OSSD Tap
The OSSD tap is designed to specifically interface with safety products that generate OSSD
outputs. The OSSD tap does not perform testing on the OSSD signals as the input device must
perform the test.
The OSSD tap verifies if the outputs of the connected device are energized or de-energized. If the
outputs are de-energized, then the tap goes to a safe state, and the input status indicator is red. If
the outputs of the device are energized, then the tap shows a solid or flashing green input status
indicator.
If the OSSD tap inputs are not the same state for 3 or more seconds, then the tap enters a
recoverable fault state. Both inputs must go to LO and then back to HI to recover.
EMSS Tap
The EMSS tap is designed to interface with two voltage-free contacts. The tap applies 24V to one
side of the contact on both channels and looks for the 24V on the monitoring input. The tap pulse
tests these contacts.
The tap verifies if both contacts are closed or open. When the contacts open, the tap goes to a
safe state, and the input status indicator is red. When the contacts close, the tap goes to an
operational state, which turns the input status indicator either solid or flashing green.
The EMSS tap has a 10 second simultaneity window. If one contact opens, the second contact must
open within 10 seconds. Similarly, if one contact closes, the second contact must close within 10
seconds. If the simultaneity window requirement is not met, the tap goes to a recoverable fault
state. To recover, both contacts must cycle open and then closed again within 10 seconds.
Passive Tap The passive tap is designed to interface with safety rated devices that have built-in GuardLink technology. The passive tap simply passes the GuardLink signals to and from the device. The
passive tap does not operate with safety devices that have OSSD or EMSS outputs.
PassivePower
Tap
The passive power tap has two significant features:
• The passive power tap acts as a passive tap by passing the GuardLink signals directly to
devices with built-in GuardLink technology
• The passive power tap allows additional power to be introduced into the GuardLink circuit to
compensate for voltage drops resulting from long cable lengths and numerous devices in the
circuit.

Chapter 1 Introduction
To maintain the integrity of the GuardLink signal, the wiring distance between
GuardLink-enabled devices is important. There are two application cases:
•Case 1: Includes Guard Locking Devices
•Case 2: No Guard Locking Devices on page 16
For both cases, the wiring distance between the taps and the safety device is
limited to 10 m (32.8 ft). Proper wiring requires at least 22 AWG (0.33 mm)
wire size for 5-conductor cables and for 8-conductor cables.
Case 1: Includes Guard Locking Devices
When the GuardLink circuit includes one or more guard locking devices, the
maximum distance between GuardLink-enabled devices is 30 m (98.4 ft). If the
distance between devices is greater than 30 m (98.4 ft), you must insert a
GuardLink-enabled tap at a maximum of every 30 m (98.4 ft). If a device is not
needed at a particular location, use a shorting plug for the device connection.
Figure 4 on page 15 shows an example GuardLink circuit that includes at least
one guard locking device.
Tap 1 is a GuardLink-enabled tap that can be connected to a guard locking or a
non-guard locking device.
Tap 2 is a passive tap, which is connected to a GuardLink-enabled device.
Figure 4 on page 15 shows tap 3 as a safety device with terminal block
connections. In this case, a cordset is used to connect the safety device to the
tap. The safety device can be a guard locking or non-guard locking device.
Because the GuardLink circuit has at least one guard locking switch, the
maximum distance between GuardLink-enabled devices is 30 m (98.4 ft).
When a passive tap is used, the cable length includes both the length of the link
cable and the length of the device cable.

Case 2: No Guard Locking Devices
Figure 5 shows an example of a GuardLink circuit with no guard locking
devices. When the GuardLink circuit excludes any guard locking devices, the
maximum distance between 2…32 GuardLink-enabled devices is 100 m (328.1
ft). The distance from the DG safety relay or the 432ES-IG3 network interface
to the first tap is limited to 30 m (98.4 ft). If a passive power tap is used with a
shorting plug, the total length between the two neighboring
GuardLink-enabled taps is 100 m (328.1 ft).
Figure 5 - Example of a Non-guard Locking Circuit
Tap Replacement
You can replace a GuardLink tap with the same type of tap while the link is
powered. When the connections are remade, the GuardLink circuit recovers
automatically.
When a GuardLink tap is replaced with another type of tap that is removed or
added to the circuit, cycle the power to the DG safety relay to relearn the
number and types of connected taps. If you use the 440R-ENETR interface,
cycle its power and update the AOP of the interface.
For applications with the 432ES network interface, momentarily remove a link
cable to cycle the power to the channel, or cycle the power to the 432ES network
interface. The 432ES network interface AOP must also be updated.
Channel Order
Each channel acts independently. You can add the nodes to any channel in any
order. For example, it is not necessary to add nodes to Channel 0 first. You can
add to Channel 1 or Channel 2 first.
Each channel can accommodate up to 32 nodes, numbered 0...31. The nodes
must be sequential with no skipping over numbers.
You can either add the hardware, then add the nodes into the Controller
Organizer (software), or vice versa. We recommend you add the hardware
before you change the controller tree as this order allows the Discover Modules
feature to add the nodes to the Controller Organizer quickly, in the correct
order, with the correct part number, and compatible electronic keying.

Chapter 1 Introduction
• Channels 0 and 1 can accommodate protocols 2.0 and 1.0.
• When multiple levels of protocol connect on a channel, the channel
operates at the lowest level. Protocol 1.0 provides basic on/off
information, with limited diagnostics. Protocol 2.0 provides on/off,
additional diagnostic information, and firmware updates.
• Channel 2 only operates with GuardLink 2.0 devices.
Terminator The terminator plays a key role in the GuardLink system. To understand the
role of the terminator helps you to understand the modifications you can apply
to the GuardLink circuit, such as how to change tap types, insert nodes, delete
nodes, and append nodes.
The terminator (Figure 6), must be installed on the J2 connector of the last tap
to complete the link connection. The terminator contains internal electrical
components specifically for a GuardLink system; other terminators cannot be
used as substitutes.
Figure 6 - Terminator (Catalog Number 898D-418U-DM2)
Figure 7 shows an example GuardLink circuit. When power is applied to the
GuardLink circuit, components in the terminator set a specific reference
voltage. The device, which connects to the terminator, reads this voltage and
determines that it is the last device. The last device is the safety source, as it
initiates the GuardLink safety signal. Upon initiation, the GuardLink safety
signal determines the number of devices and the identity of the devices in the
circuit. After initiation, the GuardLink signal monitors all devices for their
safety status.
Figure 7 - Terminator Determines the Source of the GuardLink Safety Signal
The terminator affects the closest GuardLink-enabled device. As of the date of
this publication, the device can be a Smart Tap or a 440G-MZ guard locking
switch. Additional GuardLink-enabled devices will be available in the future.
After the initial power-up and establishment of the GuardLink circuit, the
terminator plays no role. You can remove the GuardLink circuit with no effect
on the system, though this action causes the next power cycle to result in a
faulted state.
A new GuardLink configuration does not generate if you move the terminator
without a power cycle. Modifications to the GuardLink circuit are only realized
upon power-up with the terminator in place. For a simple power-up, break the
link signal at any point in the circuit before the device that last had the
terminator.

Chapter 1 Introduction
The terminator is also an important tool when you commission a new system,
troubleshoot an existing system, or make topology changes.
Commissioning Example
For example, the system requires 15 nodes. During commissioning, connect 5
nodes at a time, rather than connecting all 15 at once. After moving the
terminator, cycle power to the tap or switch from where the terminator is
removed. Reapply power to the channel after you install the terminator in its
new location.
To help troubleshoot a GuardLink system, reduce the number of taps in the
GuardLink circuit by relocating the terminator. After relocation, cycle power to the
DG safety relay to allow it to relearn how many taps are connected. If a
440R-ENETR interface is used, then you must cycle the power to it and update the
Add-on Profile (AOP) of the interface.
For applications with the 432ES network interface, momentarily remove a link
cable to cycle the power to the channel, or cycle the power to the 432ES network
interface. The 432ES network interface AOP must also be updated.
