FLEX 5000 HART I/O Modules
Top ic Pa ge
Module Overview 13
HART Communication 13
HART-enabled I/O Modules 15
Logix 5000 controllers use FLEX 5000 analog HART I/O modules to control
devices in a control system. The controllers access the modules over an
EtherNet/IP network. FLEX 5000 analog HART I/O modules use terminal base
(TB) assemblies to connect field-side wiring.
FLEX 5000 analog HART I/O modules connect a Logix controller to your
process. HART input modules (5094-IF8IH, 5094-IF8IHXT) receive signals
from process value transmitters and convert them to corresponding
measurement values for use in the Logix controller (for example, temperature,
flow, pressure, or pH). HART output modules (5094-OF8IH, 5094-OF8IHXT)
provide current or voltage output signals that adjust the settings of valves and
other devices in accord with desired process behavior.
Module and Software Compatibility
Instruments that support the HART protocol allow several process parameters
to be measured with one field device, provide status and diagnostics
information, and allow remote configuration and troubleshooting.
FLEX 5000 analog HART I/O modules implement the Producer/Consumer
network communication model for both the module itself and the HART
devices that are attached to it. This communication is an intelligent data
exchange between modules / HART devices and other system devices in which
each module / HART device produces data without first being polled. You use
the Studio 5000 Logix Designer application, version 32.02 or later, to configure
the modules and HART devices.
Controller and programming software compatibility requirements apply when
you use FLEX 5000 standard and safety I/O modules. A module type and how it
is used affect which requirements apply.
You must also consider Logix Designer application version requirements when
you design your system. For example, you can use High Availability with only
version 33 or greater of the Logix Designer application.

HART Communication The HART field communication protocol is widely accepted in industry as a
standard for digitally enhanced 4…20 mA communication with smart
(microprocessor-based) field devices. A digital signal is superimposed on the
4…20 mA current loop to provide two means of communication from the
device. The 4…20 mA analog channel lets the primary process variable be
communicated at the fastest possible rate while the digital channel
communicates multiple process variables, data quality, and device status. The
HART protocol lets these simultaneous communication channels be used in a
complementary fashion.

FLEX 5000 analog HART I/O modules support the HART protocol and perform
these operations:
• Conversion of 4…20 mA analog signals to digital numeric values in
engineering units (such as kg, m, or percent) that are used in the Logix
controller.
• Conversion of digital numeric values in engineering units to 4…20 mA
analog signals to control process devices.
• Producer/Consumer network communication model directly to each
HART device.
• Automatic collection of dynamic process data from the connected HART
device. For example, temperature, pressure, flow, or valve position.
• Automatic collection of device-specific variables from the connected
HART device.
• Execution of commands through Studio 5000 Logix Designer using
input and output tags.
• Facilitation of configuration and troubleshooting of the HART field
device from your control room using FDT/DTM supported software.
With the FLEX 5000 analog HART I/O modules, both the controller and
software for device maintenance and management can access field device
data.
14 Rockwell Automation Publication 5094-UM007B-EN-P - October 2020
The FLEX 5000 analog HART I/O modules support command-response
communication protocol in a point-to-point wiring architecture.
The FLEX 5000 analog HART I/O module is the primary master device and
continuously obtains information from the connected HART devices. The
secondary master can be used for device maintenance, for example a handheld
communicator, as shown here.
Chapter 1 FLEX 5000 HART I/O Modules
Primary master
Secondary master
(handheld communicator

Slave
Most 4…20 mA transmitters are available with a HART protocol interface. The
type of data available depends on the type of instrument.
An example application is a HART enabled mass flowmeter. The standard mA
signal from the flowmeter provides one primary measurement - flow. The mA
signal with HART provides more process information. The mA signal that
represents flow is still available. The HART configuration of the flowmeter can
be set to communicate primary variable (PV), secondary variable (SV), tertiary
variable (TV), and quaternary variable (QV). These values can represent mass
flow, static pressure, temperature, total flow, and other conditions.
Dynamic variables, device-specific variables, device status, and command
execution are all available through input and output controller tags in Studio
5000 Logix Designer.
Device status information is also provided through HART.
HART connectivity provides all this information with no changes to the
existing 4…20 mA wiring.
FDT/DTM technology through HART connectivity is supported and also
provides remote configuration and troubleshooting of HART devices through
software.
HART-enabled I/O Modules
The FLEX 5000 analog HART I/O modules have built-in HART modems, so
there is no need to install external HART multiplexers or clip-on HART
modems. The 5094-IF8IH, 5094-OF8IHXT, 5094-OF8IH, and 5094-OF8IHXT
modules have separate HART modems for each channel.
HART implementation in 5094 provides a connection between the controller
and each HART device.
A HART device that is configured in a 5094 I/O module supports a configurable
connection that can include up to four Dynamic Variables, eight Device
Variables, and four HART Commands.

Types of Analog I/O Modules
Ta b l e 3 describes the types of FLEX 5000 analog HART I/O modules.
Table 3 - FLEX 5000 Analog HART I/O Modules
Cat. No. Description
5094-IF8IH, 5094-IF8IHXT 8-channel isolated current/voltage/HART input module
5094-OF8IH, 5094-OF8IHXT 8-channel isolated current/voltage/HART output module
Power the Modules FLEX 5000 analog HART I/O modules receive the following power types:
• System-side power that powers the system and lets modules transfer
data and execute logic. System-side power is also known as Backplane
power.
• Field-side power that powers field-side devices that are connected to
some FLEX 5000 I/O modules. Field-side power is also known as
SA power.
18 Rockwell Automation Publication 5094-UM007B-EN-P - October 2020
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
System-side power begins at the FLEX 5000 EtherNet/IP adapter and passes
across the FLEX 5000 module internal circuitry via terminal base power bus,
that is, Backplane power.
Field-side power, that is, SA power begins at the first terminal base assembly
and can be daisy chained to the next terminal base assembly on the right. You
can also install a separate field-side power source to each terminal base
assembly.
For more information on how to power FLEX 5000 analog HART I/O modules,
see the FLEX 5000 EtherNet/IP Adapter User Manual, publication 5094-
UM005.
SA Power Requirements
Take note of the following when supplying SA power to your system:
• You must limit the SA field-side power source to 10 A, max, at
18...32V DC.
• Confirm that the external module power supply is adequately sized for
the total module power bus current draw in the system.
• For example, if the total module power current draw, including current
inrush requirements, is 5 A, you can use a module power supply that is
limited to 5 A.
• You must use SELV-listed power supplies for module power if there are
functional safety modules that are connected to the FLEX 5000 I/O
family.
• Not all power supplies are certified for use in all applications, for
example, nonhazardous and hazardous environments.
• Isolated source power of up to 25 mA available from the module to
simplify the channel to channel isolation wiring for current sensors.
IMPORTANT
We recommend that you use separate external power supplies for the
adapter and the adjacent terminal base. This practice can prevent
unintended consequences that can result if you use one supply.
Ownership Every I/O module in a Logix 5000 control system must be owned by a
controller, also known as the owner-controller. When the FLEX 5000 Analog
HART I/O modules are used in a Logix 5000 control system, the ownercontroller performs the following:
• Stores configuration data for every module that it owns.
• Can reside in a location that differs from the FLEX 5000 I/O modules.
• Sends the I/O module configuration data to define module behavior and
begin operation in the control system.
Each FLEX 5000 Analog HART I/O module must continuously maintain
communication with its owner-controller during normal operation.
FLEX 5000 Analog HART I/O modules are limited to one owner-controller.
Rockwell Automation Publication 5094-UM007B-EN-P - October 2020 19
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
Configure Analog HART I/O Modules
You must create a Studio 5000 Logix Designer application project for the
Logix 5000 controller that owns the FLEX 5000 analog HART I/O modules and
attached HART devices. The project includes module configuration data for
the FLEX 5000 Analog HART I/O modules.
The Studio 5000 Logix Designer application transfers the project to the ownercontroller during the program download. Data is then transferred to the
FLEX 5000 analog HART I/O modules over the EtherNet/IP network.
The FLEX 5000 analog HART I/O modules can operate immediately after
receiving the configuration data.
Connections
During module configuration, you must define the module. Among the
Module Definition parameters, you must choose a connection type for the
module. A connection is a real-time data transfer link between the ownercontroller and the module that occupies the slot that the configuration
references.
During HART device configuration, you must define the input and output tags
for any connected HART device.
When you download module configuration to a controller, the controller
attempts to establish a connection to each module in the configuration.
Because part of module configuration includes a slot in the FLEX 5000 I/O
system, the owner-controller checks for the presence of a module or connected
HART device there. If a module or HART device is detected, the ownercontroller sends the configuration. One of the following occurs:
• If the configuration is appropriate to the module or HART device that is
detected, a connection is made and operation begins.
• If the configuration is not appropriate to the module or HART device that
is detected, the data is rejected and the Studio 5000 Logix Designer
application indicates that an error occurred.
The configuration can be inappropriate for many reasons. For example, a
mismatch in electronic keying that helps prevents normal operation.
The owner-controller monitors its connection with a module and HART
devices. Any break in the connection, for example, the loss of power to the
FLEX 5000 I/O system, causes a fault. The Studio 5000 Logix Designer
application monitors the fault status tags to indicate when a fault occurs on a
module or HART device.
Connection Types Available with FLEX 5000 Analog HART I/O Modules
When configuring an analog HART input or output module, you must define
the module. Connection is a required parameter in the Module Definition. The
choice determines what data is exchanged between the owner-controller and
the module.

The module returns the following to the
owner-controller:
General fault data

When a Listen Only data connection is used, another controller owns the module.
A controller that makes a Listen Only connection to the module does not write
configuration for the module. It merely listens to the data exchanged with the ownercontroller.
IMPORTANT: If a controller uses a Listen Only connection, the connection must use the
Multicast option.
For more information on Listen Only connections, see Listen Only Mode
this case, all other connections to the module, for example, the connection to the
owner-controller must also use the Multicast option.
The module returns the following to the
owner-controller:

Data Types Available with FLEX 5000 Analog HART I/O Modules
The Module Definition includes a Data parameter that matches the module
type. Input modules use Input Data, and output modules use Output Data.
The available Data parameter choices are as follows:
• 5094-IF8IH and 5094-IF8IHXT – The Input Data choice is either Analog,
Analog and Discrete, or Discrete.
• 5094-OF8IH and 5094-OF8IHXT – The Output Data choice is always
Analog.
For more information on the Connection and Data parameter choices
available with FLEX 5000 I/O modules, see the Studio 5000 Logix Designer
application.
Requested Packet Interval
The Requested Packet Interval (RPI) is a configurable parameter that defines a
specific rate at which data is exchanged between the owner-controller and the
module.
You set the RPI value during initial module configuration and can adjust it as
necessary after module operation has begun. Valid RPI values for analog HART
I/O modules are 0.2…750 ms. Valid RPI values for HART devices are
500…9999.9 ms.
Rockwell Automation Publication 5094-UM007B-EN-P - October 2020 21
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
IMPORTANT
If you change the RPI while the project is online, the connection to the
module is closed and reopened in one of the following ways:
• You inhibit the connection to the module, change the RPI value, and
uninhibit the connection.
• You change the RPI value. In this case, the connection is closed and
reopened immediately after you apply the change to the module
configuration.
For more information on guidelines for specifying RPI rates, see the
Logix 5000 Controllers Design Considerations Reference Manual, publication
1756-RM094
.
Connection Over an EtherNet/IP Network
During module and connected HART device configuration, you must
configure the Connection over EtherNet/IP parameter. The configuration
choice dictates how input data is broadcast over the network.
The FLEX 5000 analog HART I/O modules use one of the following methods to
broadcast data:
• Multicast - Multicast connections deliver information from one sender
to multiple receivers simultaneously.
Copies of one transmission are passed to a selected subset of possible
destinations.
• Unicast - Unicast connections are point-to-point transmissions between
a source node and destination node on the network.
A transmission is sent to one destination controller depending on the
module configuration.
Unicast is the default setting. We recommend that you use Unicast because it
reduces network bandwidth usage. However, if you are using a ControlLogix
5580 High Availability controller, you must use multicast.
Multicast is more efficient than sending multiple unicast streams to multiple
notes. Use multicast in the following situations:
• FLEX 5000 I/O is used in a Redundancy application
• Communication is with multiple destinations
IMPORTANT When using a ControlLogix 5580 High Availability controller, a HART
modules occupies 1 multicast connection and HART devices occupy up
to 4 multicast connections. These connections total a maximum of 5
connections per HART module and limits the adapter to a maximum of 6
HART modules.
22 Rockwell Automation Publication 5094-UM007B-EN-P - October 2020
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
You can verify how many multicast connections are on your network by looking at
your adapter Diagnostic Overview web page.
Input Module Operation Logix 5000 controllers do not poll the FLEX 5000 analog input modules for
input data. Instead, the input modules send their input data, that is channel
and status data, at the RPI.
At the RPI, not only does the module send input data to the controller, but also
the controller sends data to the module inputs. For example, the controller
sends data to command the module to unlatch alarms or enable alarms.
FLEX 5000 analog input modules reside in a FLEX 5000 I/O system that is
accessible to a Logix 5000 controller over an EtherNet/IP network. A
FLEX 5000 EtherNet/IP adapter is the first component in a FLEX 5000 I/O
system and connects the system to the EtherNet/IP network.
FLEX 5000 analog input modules communicate input data to the FLEX 5000
EtherNet/IP adapter at the defined RPI. The input data consists of channel and
status data.
At the RPI, the following events occur.
1. The remote analog input module scans its channels for input data.
2. The module sends the data to the FLEX 5000 EtherNet/IP adapter.
3. The FLEX 5000 EtherNet/IP adapter in the FLEX 5000 I/O system sends
the data over the EtherNet/IP network.
4. One of the following:
• If the controller is directly connected to the EtherNet/IP network, it
receives the input data immediately.
• If the controller is connected to the EtherNet/IP network through
another communication module, the module sends the data to its
backplane and the controller receives it.
Output Module Operation The controller sends data to an output module at the RPI or after an
Immediate Output (IOT) instruction is executed.
Rockwell Automation Publication 5094-UM007B-EN-P - October 2020 23
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
The RPI defines when the controller sends data to the FLEX 5000 analog
output module and when the output module reads back data. The controller
sends data to an output module only at the RPI.
At the RPI, not only does the controller send data to the output module, but
also the output module sends data to the controller. For example, the output
module sends an indication of the channel data quality.
FLEX 5000 analog input modules reside in a FLEX 5000 I/O system that is
accessible to a Logix 5000 controller over an EtherNet/IP network. A
FLEX 5000 EtherNet/IP adapter is the first component in a FLEX 5000 I/O
system and connects the system to the EtherNet/IP network.
FLEX 5000 analog output modules receive output data from a controller. The
output module also sends data to the controller.
Controller to Remote Analog Output Module Data Transmission
The controller broadcasts data to its local backplane at one of the following:
•RPI
• An IOT instruction is executed.
IMPORTANT
An IOT instruction sends data to all output modules in the system
immediately, and resets the RPI timer.
Based on the RPI rate and the length of the controller program scan, the output
module can receive and readback data multiple times during one program
scan.
When the RPI is less than the program scan length, the output channels can
change values multiple times during a program scan. The owner-controller
does not depend on the program scan to complete to send data.
These events occur when the controller sends data to a FLEX 5000 output
module.
1. Data is sent in one of the following ways:
• If the controller is directly connected to the EtherNet/IP network, it
broadcasts data to the network.
In this case, skip to step 3
.
• If the controller is connected to the EtherNet/IP network via a
communication module, the controller transmits the data to the
backplane.
In this case, proceed to step 2.
2. The EtherNet/IP communication module transmits the data to the
EtherNet/IP network.
3. The FLEX 5000 EtherNet/IP adapter in the FLEX 5000 I/O system
receives the data from the network and transmits it to the backplane.
4. The remote analog output module receives the data from the backplane
and behaves as dictated by its configuration.
24 Rockwell Automation Publication 5094-UM007B-EN-P - October 2020
Chapter 2 Analog HART I/O Module Operation in a Logix 5000 Control System
Remote Analog Output Module to Controller Data Transmission
When a FLEX 5000 analog output module receives new data and the requested
data value is present on the RTB, the output module sends, or reads back a data
value back to the controller and to the rest of the control system. The data value
corresponds to the signal present at its terminals. This feature is called Output
Readback.
In addition to the Output Readback, the output module sends other data to the
controller at the RPI. For example, the module alerts the controller if a short
circuit condition exists on the module.
The following events occur when a remote FLEX 5000 analog output module
sends data to the controller at the RPI.
1. The module sends the data to the backplane.
2. The FLEX 5000 EtherNet/IP adapter in the FLEX 5000 I/O system sends
the data over the EtherNet/IP network.
3. One of the following:
• If the controller is directly connected to the EtherNet/IP network, it
receives the input data from the network without need for a
communication module.
• If the controller is connected to the EtherNet/IP network through
another communication module, the module transmits the data to its
backplane and the controller receives it.
Listen Only Mode Any controller in the system can listen to the data from an I/O module. An
owner-controller, as described in Ownership
analog I/O modules.
Other controllers can use a Listen Only connection with the analog I/O
module. In this case, the ‘listening’ controller can only listen to input data or
output readback data. The listening controller does not own the module
configuration or exchange other data with the module.
During the I/O configuration process, you can specify a Listen Only
connection. For more information on Connection options, see Input Module
Definition on page 76.
IMPORTANT
Remember the following:
• If a controller uses a Listen Only connection, the connection must use
the Multicast option. In this case, all other connections to the module,
for example, the connection of the owner-controller, must also use the
Multicast option.
• If a controller attempts to use a Listen Only connection to a module but
the owner-controller connection uses the Unicast option, the attempt at
a Listen Only connection fails.
The ‘Listen Only’ controller receives data from the module as long as a
connection between an owner-controller and module is maintained.
• If the connection between an owner-controller and the module is
broken, the module stops sending data and connections to all ‘listening
controllers’ are also broken.
• Connected HART devices cannot be added to Listen Only connections.

HART Device Operation Before using the HART capabilities, be sure that:
• the I/O module and the associated field device are working properly in
the analog 4…20 mA mode.
• the channel is configured as 4…20 mA range with HART enabled.
• the field device is HART capable.
• no more than one HART field device is connected to each channel.
• Notch Filter of input channel or Ramping Rate of output channel is set to
a valid value.
Input data of HART device, that is device status, dynamic, or device variable
values and status, are sent to Logix Controller at the RPI.
At the RPI, not only does the module send input data of the HART devices to
the controller, but also the controller sends data for the HART devices to the
module. For example, the controller sends data to reset Configuration
Changed status or initiate an execution of a pre-configured HART command.
IMPORTANT If you switch the controller to Program mode or inhibit an output
module, it may cause the output channels to de-energize and the HART
device to not power up.
To power up the HART device, switch the controller to Run mode and
uninhibit the output module.

This chapter describes module features that are available on both FLEX 5000
HART input and output modules.
FLEX 5000 analog HART input modules convert an analog signal to a digital
value. For example, the modules can convert the following:
•Volts
•Milliamps
You can configure FLEX 5000 HART input modules to support digital input
signals when your application requires channel to channel isolation. The
following types of discrete device types are supported:
• Digital Input
• IEC 61131-2 Type 3-d Digital Input
For information on digital input points, see Chapter 5
FLEX 5000 analog HART output modules convert a digital value to an analog
signal. For example, the modules can convert the following:
•Volts
•Milliamps
FLEX 5000 analog HART enabled modules decodes HART information from
signal embedded within the channel.
Software Configurable You use the Studio 5000 Logix Designer application to configure the module,
monitor system operation, and troubleshoot issues. You can also use the
Studio 5000 Logix Designer application to retrieve the following information
from any module in the system:
• Serial number
Rockwell Automation Publication 5094-UM007B-EN-P - October 2020 29
Chapter 3 Common I/O Module Features
• Firmware revision information
• Product code
•Vendor
• Error and fault information
• Diagnostic information
By minimizing the need for tasks, such as setting hardware switches and
jumpers, the software makes module configuration easier and more reliable.
Fault and Status Reporting The FLEX 5000 analog HART I/O modules report fault and status data along
with channel data. Fault and status data is reported in the following ways:
• Studio 5000 Logix Designer application
• Module status indicators
For more information on fault reporting, see the individual module feature
chapters and Appendix A, Troubleshoot Your Module
on page 107.
Module Inhibiting Module inhibiting lets you indefinitely suspend a connection, including Listen
Only connections, between an owner-controller and an analog I/O module
without removing the module from the configuration. This process lets you
temporarily disable a module, such as to perform maintenance.
IMPORTANT
You can use module inhibiting in the following ways:
• You write a configuration for an I/O module but inhibit the module to
help prevent it from communicating with the owner-controller. The
owner does not establish a connection and the configuration is not sent
to the module until the connection is uninhibited.
• In your application, a controller already owns a module, has downloaded
the configuration to the module, and is exchanging data over the
connection between the devices.
You can use module inhibiting in these instances:
• You want to update an analog I/O module, for example, update the
module firmware revision. Use the following procedure.
a. Inhibit the module.
b. Perform the update.
c. Uninhibit the module.
• You use a program that includes a module that you do not physically
possess yet. You do not want the controller to look for a module that does
not yet exist. In this case, you can inhibit the module in your program
until it physically resides in the proper slot.
Once a module is inhibited, the connections to the module and attached
HART devices are also closed and the CIP messaging to the HART
devices is disabled.
To see where to inhibit a FLEX 5000 analog HART I/O module, see page 77
