About the Modules
What This Chapter Contains
This chapter includes important overview information and precautions
for use of the safety I/O modules that implement the DeviceNet safety
protocol. Also included is an overview on how these I/O modules are
used within a safety system.
Before You Begin
Always observe the following when using a module, noting that in
this manual we use safety administrator to mean a person qualified,
authorized, and responsible to secure safety in the design, installation,
operation, maintenance, and disposal of the machine.
Make sure that a safety administrator who thoroughly
understands the machine to be installed handles the module.
Thoroughly read and understand this manual before installing
and operating the module.
Keep this manual in a safe place where the operator can refer to
it when necessary.
Use the module properly according to the installation
environment, performance, and functions of the machine.
Verify that a safety administrator conducts a risk assessment on
the machine and determines module suitability before
installation.
Verify that the external power supply that provides power to the
I/O modules is safety extra-low voltage (SELV) rated.
Verify that the DeviceNet block safety I/O firmware version is
correct prior to commissioning the safety system, noting that
firmware information related to safety controllers is available at
http://www.rockwellautomation.com/products/certification/
safety/index.html.

About the Modules
Understand Suitability for
Use
Rockwell Automation is not responsible for conformity with any
standards, codes, or regulations that apply to the combination of the
products in your application or use of the product.
Take all necessary steps to determine the suitability of the product for
the systems, machine, and equipment with which it is used.
Know and observe all prohibitions of use applicable to this product.
Never use the products for an application involving serious risk to life
or property without making sure that the system as a whole was
designed to address the risks and that the Rockwell Automation
product is properly rated and installed for the intended use within the
overall equipment or system.
Follow Precautions for Use
ATTENTION
Safety state of the module and its data is defined as the off
state.
Use the module in applications where the safety status for
the module is off (0).
Serious injury may occur due to breakdown of safety outputs.
Do not connect loads beyond the rated value to the safety
outputs.
Serious injury may occur due to loss of required safety
functions. Wire the module properly so that supply voltages
or voltages for loads do not touch the safety outputs
accidentally or inadvertently.
ATTENTION
Use dc supply satisfying the following requirements to
prevent electric shock:
A dc power supply with double or reinforced insulation,
for example, according to IED/EN 60950 or EN 50178 or a
transformer according to IEC/EN 61558
A dc supply satisfies requirement for class 2 circuits or
limited voltage/current circuit stated in UL 508
Publication 1791DS-UM001E-EN-P - January 2007
About the Modules
ATTENTION
9
Follow these precautions for safe use.
Wire conductors correctly and verify operation of the module
before commissioning systems in which the module is
incorporated. Incorrect wiring may lead to loss of safety
function.
Do not apply dc voltages exceeding the rated voltages to the
module.
Apply properly specified voltages to the module inputs.
Applying inappropriate voltages causes the module to fail to
perform its specified function, which leads to loss of safety
functions or damage to the module.
Never use test outputs as safety outputs in any way. Test
outputs are not safety outputs.
Note that after installation of the module, qualified
personnel must confirm the installation and conduct trial
operation and maintenance.
Note that a safety administrator familiar with the machine in
which the module is to be installed must conduct and verify
the installation.
Do not disassemble, repair, or modify the module. This may
result in loss of safety functions.
Use only appropriate components or devices complying with
relevant safety standards corresponding to the required
safety category and safety integrity level.
Conformity to requirements of the safety category and
safety integrity level must be determined for the entire
system.
We recommend you consult a certification body
regarding assessment of conformity to the required
safety integrity level.
Note that you must confirm compliance with the applicable
standards for the entire system.
Disconnect the module from the power supply before wiring.
Devices connected to the module may operate unexpectedly
if wiring is performed while power is supplied.
Publication 1791DS-UM001E-EN-P - January 2007

About the Modules
For 1791DS-IB4XOW4 modules, follow these instructions on isolating
transformer use. Refer to the isolating transformer figure.
Use an isolating transformer to isolate between over-voltage
category III and II, such as TR1, to conform to IEC 60742.
Be sure the insulation between first input and secondary output
satisfies at least basic insulation of over-voltage category III.
Be sure one side of a secondary output of the isolating
transformer is grounded to prevent electric shock to personnel
due to a short to ground or short to the frame of the isolating
transformer.
Insert fuses, in case of a short to the frame, to protect the
isolating transformer and prevent electric shock to personnel,
per transformer specifications, at points such as F1, F2, and F3.

Follow Precautions for
Mounting, Wiring, and
Cleaning
11
Observe these precautions to prevent operation failure, malfunctions,
or undesirable effects on product performance.
When mounting modules, observe these precautions.
Use DIN rail that is 35 mm (1.38 in.) wide to mount the module
into the control panel.
Mount modules to DIN rail so that the module does not fall off
the DIN rail, for example, due to vibration.
Leave at least 50 mm (1.96 in.) above and below the module to
allow adequate ventilation and room for wiring for 1791DS-IB8,
1791DS-IB8XOB8, and 1791DS-IB4XOW4 modules.
Leave at least 5 mm (0.6 in.) above and below the module to
allow adequate ventilation and room for wiring for 1732DS-IB8,
1732DS-IB8XOBV4, and 1791DS-IB8XOBV4 modules.
When wiring modules, follow these instructions.
Do not place communication lines and I/O lines in the same

About the Modules
I/O Module Overview
The Guard I/O modules implement the CIP-safety protocol extensions
over DeviceNet networks and provide various features for a safety
system.
Use the modules to construct a safety-control network system that
meets the requirements for Safety Integrity Level 3 (SIL 3) as defined
in IEC 61508, Functional Safety of Electrical, Electronic, and
Programmable Electronic Safety-related Systems, and the requirements
for Safety Category 4 of the EN 954-1 standard.
Remote I/O communication for safety I/O data are performed through
safety connections supporting CIP safety over a DeviceNet network,
and data processing is performed in the safety controller.
The status and fault diagnostics of safety I/O modules is monitored by
a safety PLC through a safety connection using a new or existing
DeviceNet network.
Here is a list of features common to all Guard I/O modules.
CIP-safety protocol conformance
Safety inputs
– Contact output devices, such as emergency stop push
buttons, gate switches, and safety light curtains, can be
connected.
– Dual-channel mode evaluates consistency between two input
signals (channels), which allows use of the module for Safety
Category 4.
– The time of a logical discrepancy between two channels can
be monitored using a discrepancy time setting.
– An external wiring short-circuit check is possible by turning
on an input. The module must be wired in combination with
test outputs when this function is used.
– Independently adjustable on and off delay is available per
channel.
Test outputs
– Separate test outputs are provided.
– Broken wires detection is supplied on muting outputs.
– Power (24V) can be supplied to devices, such as safety
sensors.
– Test outputs can be set as standard outputs for use as monitor
outputs.
– All Guard I/O modules have numerous test outputs, of which
some can be used for control and monitoring of a muting
lamp.

Safety Communication
Standard Communication
Safety input devices such as emergency-stop switches and safety
output devices, such as safety contactors, can be connected to safety
I/O blocks. Standard devices, such as proximity switches,
pushbuttons, or lamps, can also be connected to safety I/O blocks.
Safety PLC controllers or safety network controllers control the safety
outputs. Safety PLC controllers, safety network controllers, or standard
PLC controllers can control the standard outputs.
The modules provide self-diagnostics to test the electronics within the
module. The safety outputs provide a pulse test feature for diagnosing
the external wiring of field actuators. Testing of input wiring is by
connecting the field input devices to one of the pulse test outputs
provided by the modules. Any pulse test outputs not used to test input
wiring can be used as a standard output. At least one of these
standard outputs is configurable with current monitoring to use it for
control and monitoring of a muting lamp.
Publication 1791DS-UM001E-EN-P - January 2007
About the Modules
15
The modules also allow configuration of input points as dual inputs,
and configuration of output points as dual outputs. The module
performs internal diagnostics on I/O channels configured to operate
in Dual mode.
Any discrepancy results in a safety state and status generated for the
master. Configuration of DeviceNet Guard I/O modules is via software
using either the network configuration tool, RSNetWorx for DeviceNet
Safety software, or the PLC programming tool, RSLogix 5000 software.

Set Dual-channel Mode and Discrepancy Time
The consistency between signals on two channels can be evaluated.
Either equivalent or complementary can be selected. This function
monitors the time during which there is a discrepancy in the logic
between the two channels set as dual channels.
If the length of the discrepancy exceeds the set discrepancy time
(0…65,530 ms in increments of 10 ms), the safety input data and the
individual-safety input status turns off for both inputs.
IMPORTANT
The dual-channel function is used with two
consecutive inputs that start from even input
numbers such as inputs 0 and 1, inputs 2 and 3, and
inputs 4 and 5.
The following table shows the relation between terminal input status
and remote I/O data.

Fault Recovery
If an error is detected, the safety input data remains in the off state.
The procedure for activating the safety input data again is as follows.
1. Remove the cause of the error.
2. Turn off the safety input.
The safety input status turns on after the input-error latch time
has elapsed. The I/O indicator (red) turns off. The input data
can now be controlled.
Input Delays
On-delay - An input signal is treated as being off during the on-delay
setting time (0…126 ms, in increments of 6 ms) after the input
contact’s rising edge. The input turns on only if the input contact
remains on after the on-delay time has elapsed. This helps prevent
chattering of the input contacts.

contact’s falling edge. The input turns off only if the input contact
remains off after the off delay time has elapsed. This helps prevent
chattering of the input contacts.

Safety Output with Test Pulse
When the output is on, the test pulse is turned off in a cycle for a
period of time as shown in the the table and figure.
Using this function, short-circuits between output signal lines and the
power supply (positive side) and short-circuits between output signal
lines can be detected. If an error is detected, the safety output data
and individual-safety output status turns off.

Fault Recovery
If a fault is detected, the safety output remains in the off state. The
procedure for activating the safety output data again is as follows.
1. Remove the cause of the error.
2. Turn off the safety output or outputs.
The safety output status turns on when the output-error latch
time has elapsed. The I/O indicator (red) turns off. The output
data can now be controlled.
I/O Status Data
In addition to I/O data, the module supports status data to check the
I/O circuits. The status data includes the following data, which can be
read by the PLC controllers.
Individual Point Input Status
(ON = Normal/OK, OFF = Fault/Alarm)
Combined Input Status
(ON = Normal/OK, OFF = Fault/Alarm)
Individual Point Output Status
(ON = Normal/OK, OFF = Fault/Alarm)
Combined Output Status
(ON = Normal/OK, OFF = Fault/Alarm)
Individual Output Readback
(actual ON/OFF state of the outputs)
Individual Test Output Status
(ON = Normal/OK, OFF = Fault/Alarm)
Normal flags indicate whether each safety input, safety output, or test
output is normal (normal status: ON, error (fault) status: OFF). For
fatal errors, communication connections may be broken, so the status
of the normal flags then cannot be read.
Combined flags are provided for an AND of the status of all safety
inputs or all safety outputs (when all inputs or outputs are normal:
ON, when one or more of them has an error: OFF). This is known as
the combined safety input/output status.
Output monitors indicate the actual ON/OFF status of each safety
output.

Japan
In Japan, type test requirements are provided in Article 44 of the
Industrial Safety and Health Law. These requirements apply to
complete systems and cannot be applied to a module by itself.
Accordingly, to use the module in Japan as a safety device for press
machine or shearing tool pursuant to Article 42 of the
above-mentioned law, it is necessary to apply for testing of the entire
system.
EC Directives
DeviceNet products conform to the EMC Directive and Low-voltage
Directive.
EMC Directive
Rockwell Automation devices that comply with EC directives also
conform to the related EMC standards so that they can more easily be
built into other devices or the overall machine. The actual products
have been checked for conformity to EMC standards. Whether they
conform to the standards in the system used by the customer,
however, must be confirmed by the customer.
EMC-related performance of Rockwell Automation devices that
comply with EC directives vary depending on the configuration,
wiring, and other conditions of the equipment or control panel in
which the Rockwell Automation devices are installed. The customer
must, therefore, perform the final check to confirm that devices and
the overall machine conform to EMC standards.
Compliance with EC Directives
DeviceNet products that comply with EC directives must be installed
as follows.
All Type IP20 DeviceNet units must be installed within control
panels.
Use reinforced insulation or double insulation for the dc power
supplies used for the communication power supply, internalcircuit power supply, and the I/O power supplies.
Publication 1791DS-UM001E-EN-P - January 2007
34
Understand the Operation of Safety Functions
DeviceNet products that comply with EC directives also conform
to the Common Emission Standard (EN 50081-2). Radiated
emission characteristics (10-m regulations) may vary depending
on the configuration of the control panel used, other devices
connected to the control panel, wiring, and other conditions.
You must confirm that the overall machine or equipment
complies with EC directives.
DeviceNet products that comply with EC directives must have
configurations with less than 30 m (98.43 ft) of I/O wiring and
less than 10 m (32.81 ft) of power supply wiring, which applies
to the 1791DS-IB12, 1791DS-IB8XOB8, and 1791DS-IB4XOW4

Install and Connect Your Modules
What This Chapter Contains
This chapter explains these general procedures for module use:
Install the module in the control panel.
Wire I/O power and cables.
Connect communication connectors.
Set the node address.
Configure the system, making settings for the module.
The communication baud rate of the entire network is determined by
the communication baud rate of the master unit. The communication
baud rate does not need to be set for each module.
ATTENTION
Test Output points configured as Pulse Test or Power Supply
become active whenever you apply network power and input
power to the module. These configured functions are
independent of the I/O connections to the module.
You can configure Test Outputs as Standard when they are used
as standard outputs. You can connect Actuators to Test Output
points that are expecting a Standard configuration.
If a module with Test Outputs configured as Pulse Test or Power
Supply is incorrectly installed in an application where actuators
are connected to these Test Output points, the actuators will be
activated when network power and input power are applied.
To prevent this possibility, use the following procedures:
When installing a module, be sure that the module is
correctly configured for the application or in the
out-of-box condition before applying input power.
When replacing a module, be sure that the module is
correctly configured for the application or in the
out-of-box condition before applying input power.
Reset modules to their out-of-box condition when
removing them from an application.
Be sure that all modules in replacement stock are in
their out-of-box condition.

Use a Phoenix Contact crimping tool (model CRIMPFOX UD6) for the
ferrules.
When crimping connection cables, follow these
instructions.
IMPORTANT
Use ferrules when wiring cables.
Note that I/O connectors are detachable.
Tighten the screws on the I/O connector to
0.25…0.3 Nm (2.16…2.59 lb-in).
Since the I/O connector has a structure that
helps prevent incorrect wiring, make
connections at the specified locations
corresponding to the terminal numbers.
Do not remove the shield from the module
before wiring.
Always remove the shield after completing
wiring to be sure of proper heat dispersion.

C. For Description, if desired, type a description.
For a detailed explanation of the safety network number (SNN),
see the GuardLogix Controller Systems Safety Reference Manual,
publication 1756-RM093, noting that in most cases, you use the
default provided by the RSLogix 5000 software.
Read the following for an overview explanation of why the
safety network number exists for DeviceNet safety.
The purpose of a SNN is to make sure that every module in a
system can be uniquely identified.
Publication 1791DS-UM001D-EN-P - January 2007
Configure Modules in RSLogix 5000 Software
45
For example, assume there are two identical GuardLogix
control systems - system A and system B - that are connected
to a common Ethernet network. Each GuardLogix control
system has three DeviceNet networks with assorted standard
and safety I/O modules. In a system like this, modules can
have the same node number, but no two modules have the
same SNN and node number combination.
If 1756-DNB modules were in the same chassis, and the
DeviceNet cables were inadvertantly disconnected, if
reattached incorrectly, the connections to the safety modules
are broken, because the 1756-DNB module is now connected
to devices with a different SNN.
Note that we suggest that all safety modules on a network have
the same SNN. This makes documentation easier. During
configuration, RSLogix 5000 software defaults a safety device’s
SNN to match the SNN of the lowest safety node on the
network.

See GuardLogix Controllers
User Manual, publication
number 1756-UM020, for more
information about the CRTL.
Make sure that input modules are set to match the need. The
smallest input RPI allowed is 6 ms. Selecting small RPI's
consumes network bandwidth and may cause nuisance trips
because other devices can't get access to the network.
As an example, a safety input module with only ESTOP switches
connected to it generally may work well with settings of
50…100 ms. An input module with a light curtain guarding a
hazard may need the fastest response that is possible.
Selecting appropriate RPI's will result in a system with maximum
(best) performance.
IMPORTANT
Publication 1791DS-UM001D-EN-P - January 2007
You should always analyze each safety channel to determine what is
appropriate. These examples are simply to convey concepts and
should not be used as any kind of official recommendation.

A connection status tag exists for every connection.
Connection
Faulted
If the RPI and CRTL for the network are set appropriately,
then this status tag will always remain HI. Monitor all
connection status bits to verify that they are not going LO
intermittently due to timeouts.
The configuration signature is created by RSLogix 5000 software
and verified by the safety module. The configuration signature
provides SIL 3 integrity of the configuration of a 1791DS module.
When a GuardLogix first connects to a 1791DS module, the
complete configuration is downloaded to the I/O module.
Any time the GuardLogix controller attempts to connect to a
1791DS module, if the configuration signatures are the same,
then the configuration does not need to be downloaded,
because they already match.
Any time the GuardLogix controller attempts to connect to a
1791DS module and the signatures do not match, the module
will check the module node number, keying, and safety
network number. If these are all correct, the controller will
attempt to configure the module.

Safety Test Pulse
The input is disabled. It remains logic 0 if 24V is applied to the input terminal.
Pulse testing is performed on this input circuit. A test source on the 1791DS
module must be used as the 24V source for this circuit. The test source is
configured using the test source pulldown. The pulse test will detect shorts
to 24V and channel-to-channel shorts to other inputs.
A safety input is connected but there is no requirement for the 1791DS
module to perform a pulse test on this circuit. An example is a safety device
that performs its own pulse tests on the input wires, such as a light curtain.
A standard device, such as a reset switch, is connected.
If pulse testing is being performed on an input point, then the test source that
is sourcing the 24V for the input circuit must be selected.

1. For Point Operation, for Type, select one of these and a value
for Discrepancy Time if set to Equivalent or Complementary:
Single
Inputs are treated as single channels. Note that in many cases,
dual-channel safety inputs are configured as two individual
single channels. This does not affect pulse testing because it
is handled on an individual channel basis.
Equivalent(1)
Inputs are treated as a dual-channel pair. The channels must
match within the discrepancy time or an error is generated.
Complementary(1)
Inputs are treated as a dual-channel pair. They must be in
opposite states within the discrepancy time or an error is
generated.

Be aware that configuring discrepancy time on safety I/O modules masks input inconsistent faults from the
safety controller.

Safety Pulse Test - Safety input is configured for pulse test
operation
Safety - Safety input is used with a safety field device
Standard - Safety input has a standard field device wired to it
3. Complete entries, noting the following:
For each safety input on the module, you can define if the
input will be pulse tested. If the inputs will be pulse tested,
select which test source to use. Test sources, such as 0…3,
correlate to the standard outputs, such as 0…3, on the
module. Test sources, such as 0…7, correlate to standard
outputs, such as 0…7, on 1791DS-IB8XOBV4 modules.
Off -> On and On -> Off delay times can be configured per
channel with each channel specifically tuned to match the
characteristics of the field device for maximum performance.
Input Error Latch Time is the time the module holds an error
to make sure the controller can detect it. This provides you
more reliable diagnostics and enhances the chances that a
nuisance error is detected.

Name(1)
x Point
Operation
Type
Value
Description
Default
Single
The output is treated as a single channel.
Dual-channel
The 1791DS module treats the outputs as a pair. It always sets them HI to LO as a
matched pair.
Safety logic must set both of these outputs ON or OFF at the same time or the module
will declare a channel fault.
x Point Mode Not Used
The output is disabled.
Not Used
Safety
The output point is enabled, and it does not perform a pulse test on the output.
Safety Pulse Test The output point is enabled and performs a pulse test on the output.
When the output is energized, the output pulses LO briefly. The pulse test detects if
24V remains on the output terminal during this LO pulse due to a short to 24V or if the
output is shorted to another output terminal.
1000 ms
x Output Error 0…65,530 ms (in The purpose for latching output errors is to make sure that intermittent faults that
Latch Time increments of 10 may only exist for a few milliseconds are latched long enough to be read by the

Save Module Configuration
We recommend that after a module is configured you save your work.
After downloading the program, if the MS and NS LED indicators on
the 1791DS module are not both solid green, this may be due to loss
of ownership. The ownership is based on the following:
1791DS DeviceNet node number
1791DS safety network number
GuardLogix slot number
GuardLogix safety network number
If any of these change, the connection between the GuardLogix
module and the 1791DS module is lost, and the yellow yield in the
RSLogix 5000 tree appears. Reset ownership to reestablish the
connection using this procedure.
1. From within RSLogix 5000 software, open the safety I/O module
properties.
2. Click the Safety tab.
3. From the dialog, click Reset ownership.
Status Data Supported by
Each Module

Maintenance
Read this section for information about routine cleaning and
inspection recommended as regular maintenance. Handling methods
when replacing the module are also explained here.
Clean the Modules
Clean the module regularly using these guidelines to keep the
network in optimal operating condition.
• Wipe the module with a dry, soft cloth for regular cleaning.
• When dust or dirt cannot be removed with a dry cloth, dampen
the cloth with a neutral cleanser (2%), wring out the cloth, and
wipe the module.
• When cleaning, remove smudges that remain on the module
from gum, vinyl, or tape left on for a long time.
IMPORTANT
Publication 1791DS-UM001E-EN-P - January 2007
Never use volatile solvents, such as paint thinner, benzene, or
chemical wipes, to clean the module. These substances may
damage the surface of the module.
Maintain Your Modules
107
Inspect the Modules
Inspect the system periodically to keep it in optimal operating
condition. In general, inspect the system once every 6 or 12 months,
but inspect more frequently if the system is used in high-temperature,
humid, or dusty conditions.
Prepare the following equipment before inspecting the system.
• Equipment required for regular inspection
– Phillips screwdriver
– Flat-blade screwdriver
– Screwdriver for connecting communication connectors
– Tester (or digital voltmeter)
– Industrial alcohol and clean cloth
• Other equipment that can be required
– Synchroscope
– Oscilloscope
– Thermometer or hygrometer

Maintain Your Modules
Replace Modules
The network consists of the DeviceNet master unit and safety I/O
modules. The entire network is affected when a safety I/O module is
faulty, so a faulty module must be repaired or replaced quickly. We
recommend having spare modules available to restore network
operation as quickly as possible.
Observe the following precautions when replacing a faulty module.
• After replacement, be sure there are no errors with the new
module.
• When returning a module for repair, attach a detailed
description of the problem and return the module to your
Rockwell Automation representative.
• If there is a faulty contact, wipe the contact with a clean,
lint-free cloth dampened with alcohol.
IMPORTANT
Perform a system test of the related safety functions after
replacing a module.
After replacing a module, set the new module’s switches to the same
settings that were on the old module. For related information see the
following publications.
• GuardLogix Controllers User Manual, publication 1756-UM020,
for information on replacing a module in the system
• GuardLogix Controller Systems Safety Reference Manual,
publication 1756-RM093, for safety considerations when
replacing I/O

• Destination Node Address - The node address of the module
that is sending the explicit messages is specified with a 1 byte
hexadecimal.
• Service Code, Class ID, Instance ID, Attribute ID - The
parameters used for specifying the command, processing object,
and processing content.
• Data - Data is not required when the read command is used.

Probability of Failure on Demand (PFD),
Probability of Failure per Hour (PFH), and
Mean Time Between (MTBF) Data
What This Appendix
Contains
This appendix lists calculated values for probability of failure on
demand, probability of failure per hour, and mean time between
failure.
Calculated Values
See the table that shows the values.
Calculated values of probability of failure on demand and probability
of failure per hour appear in the table and must be calculated for the
overall devices within the system to comply with the SIL level
required for application.
IMPORTANT
The proof test interval of the 1791DS-IB4XOW4 module must
not exceed 0.5 years because the maintenance interval for the
relay contacts must not exceed a period of 6 months to satisfy
safety category 4 in accordance with EN954-1.
Within the proof test interval, every I/O module must be functionally
tested by individually toggling each input point and verifying that it is
detected by the controller. Additionally, each output point must be
individually toggled by the controller and user-verified that the output
point changes state.

Safety Inputs
Item
Input Channel Mode
Dual-channel Mode
Input Delays
Description
Any of the following modes can be selected according to the external input device for each input.
• Not used - An external input device is not connected.
• Safety pulse test - Used with a contact output device in combination with a test output. Using this
setting, short circuits between input signal lines and the power supply (positive side) and short circuits
between input signal lines can be detected.
• Safety - A solid-state output safety sensor is connected.
• Standard - A standard device is connected, for example, a reset switch.
The consistency between signals on two channels can be evaluated. The following settings can be selected.
The discrepancy time is set for Dual-channel operation.
• Single channel - Used as a single channel.
• Dual-channel equivalent - Used as a dual channel pair. Status is OK when both channels are ON or
OFF.
• Dual-channel complementary - Used as dual channel. Status is OK when one channel is ON and the
other channel is OFF.
ON delay An input signal is treated as being OFF during the ON delay setting time (0…126 ms, in increments of 6 ms)
after the input contact’s rising edge.
The input turns ON only if the input contact remains ON after the ON delay time has elapsed.
This helps prevent chattering of the input contacts.
OFF delay An input signal is treated as being ON during the OFF delay setting time (0…126 ms, in increments of 6 ms)
after the input contact’s falling edge.
The input turns OFF only if the input contact remains OFF after the OFF delay time has elapsed.
Input Error Latch Time
This helps prevent chattering of the input contacts.
An input or test output error is held for a minimum of this amount of time.
This time should be set to ensure that the Safety Controller recognizes the error (0…65,530 ms, in increments
of 10 ms).

Description
Any of the following Safety Output modes can be selected.
• Not used - External output devices are not connected.
• Safety - When the safety output is ON, the test pulse is not output (remains ON).
Dual Channel Setting
• Safety pulse test - When the output is ON, the test pulse is turned OFF for 470 µs in a cycle of 648 ms.
Using this function, short-circuits between output signal lines and the power supply (positive side) and
short-circuits between output signal lines can be detected.
The consistency between signals on two channels can be evaluated.
Either of the following settings can be selected for 1791DS-1791DS-IB8XOB8 and 1791DS-IB4XOW4.
Dual-channel is the only setting for 1791DS-IB8XOBV4 and 1732DS-IB8XOBV4.
• Single channel - used as single channel.
• Dual channel - when both channels are OK, outputs can be turned ON. If an error is detected on one of
the channels, the other channel is also turned OFF.
Output Error Latch Time A safety output error will be held for a minimum of this amount of time. This time should be set to be sure that
the safety controller recognizes the error. (0…65,530 ms, in increments of 10 ms)
Short-circuit Protecton Supported.

Appendix
E
Get Point Status from Safety I/O Modules by
Using Explicit Messaging
What This Appendix
Contains
This appendix provides information about how to use explicit
messaging to get point status information from safety I/O modules.
One of the variables in maximizing throughput when using DeviceNet
safety I/O modules is the size of the I/O assembly, with the other
variables being the requested packet interval and baud rate.
For maximum throughput you need to keep the I/O assembly at two
bytes or fewer. The two-byte I/O assemblies do not provide the
individual point status needed to quickly diagnose what point faulted
from an operator terminal. Read this appendix for a description of
how to get the point status via explicit messaging.
Work with
1791DS-IB8XOB8 Modules
141
To work with 1791DS-IB8XOB8 modules, follow this procedure.
1. From the Module Definition dialog, use Combined Status-Muting
for Input Status.
Publication 1791DS-UM001E-EN-P - January 2007
142
Get Point Status from Safety I/O Modules by Using Explicit Messaging
This creates a two-byte input assembly, as shown for a module
called IB8XOB8.
2. Use the combined InputStatus and combined OutputStatus bits
to detect if one or more of the I/O points on the module have a
fault.
• If either InputStatus or OutputStatus bit goes low
(l0 = bad; 1 = good), use an explicit message to determine
which individual data points have faulted.
• Use the InputStatus and OutputStatus bits to condition your
msg rungs as follows.
• Note that the second rung can be used to read the status on
mode transition and once a fault is detected, continue reading
until the fault is corrected.
Publication 1791DS-UM001E-EN-P - January 2007
Get Point Status from Safety I/O Modules by Using Explicit Messaging
143
See the figure that shows 1791DS-IB8XOB8 message instruction
parameters.
Note that we created a UDT for the destination type.
• You can find the UDT called Assembly803_1791DS_IB8XOB8
in an ACD file. This UDT is based on the Assembly803 for
1791DS_IB8XOB8 module.
• There are other assemblies in the EDS file that can be used,
but this one is the most inclusive.
• Make sure the Communication Path is set to the correct
module.

Work with
1791DS-IB4XOW4 Modules
145
To work with 1791DS-IB4XOW4 modules, follow this procedure.
1. From the Module Definition dialog, use Combined Status-Muting
for the Input Status.
This creates a one-byte assembly, as shown in the figure, for a
module called IB4XOW4.
2. Use the combined InputStatus and combined OutputStatus bits
to detect if one or more of the I/O points on the module have a
fault.
• If either InputStatus or OutputStatus bit goes low (0 = bad;
1 = good) use an explicit message to determine which
individual data points have faulted.
• Use the InputStatus and OutputStatus bits to condition your
msg rungs as shown in the figure.

instruction parameters.
Note that we created a UDT for the destination type.
• You can find the UDT call Assembly819_1791DS_IB4XOW4 in
the ACD file. This UDT is based on Assembly819 for
1791DS_IB4XOW4 module.
• There are other assemblies in the EDS file that can be used,
but this one is the most inclusive.
• Make sure the communication path is set to the correct
module.

Work with 1791DS-IB12
Modules
To work with 1791DS-IB12 modules, follow this procedure.
1. From the Module Definition dialog, use Combined Status-Muting
for the Input Status.
This creates a two-byte input assembly, as shown in the figure,
for a module called IB12.
2. Use the CombinedStatus bit to detect if one or more of the I/O
points on the module have a fault.
• If the CombinedStatus bit goes low (0 = bad; 1 = good) use an
explicit message to determine which individual data points
have faulted.
• Use the CombinedStatus bits to condition your msg rungs as
shown in the figure.

• Note that you can use the second rung to read the status on
mode transition and once a fault is detected, continue reading
until the fault is corrected.
See the figure that shows 1791DS-IB12 message instruction
parameters.
Note that we created a UDT for the destination type.
• You can find the UDT called Assembly786_1791DS_IB12 in
the ACD file. This UDT is based on Assembly786 for the
1791DS_IB12 module.
• There are other assemblies in the EDS file that can be used
