Modern flow control software driver based on FDT/DTM technology extends standardized device management to mobile and OPC UA applications.
Glad to see movement with the latest technology from the FDT Group. It certified the first Device Specific DTM based on FDT 3.0 standard supporting the HART protocol from Flowserve Corp. The newest certified Logix 3820 Series DTM is deployable using their positioners supporting HART 6 / 7, tackling flow control challenges designed for modern IIoT architectures.
FDT DTM certification to the FDT 3.0 specification and webUI is a process whereby rigorous compliance testing using dtmINSPECTOR5 ensures the viability of the states of the DTM; its correct installation, de-installation, and multi-user environment capability; mandatory and optional user interface functionality and robustness; network scanning communication performance and the ability to import and export the topology; and the audit trail capability.
FDT 3.0 DTMs are crucial to unlocking universal device integration with essential advantages such as platform independence, mobility solutions, and a contemporary development environment to reduce costs and expedite the DTM certification process. Users can use secure and seamless data exchange/interrogation from the sensor to the cloud and achieve new levels of information technology (IT) and operational technology (OT) integration.
“This certification is a milestone in market penetration and technology development,” says Steve Biegacki, FDT Group managing director. “Flowserve has always been a leader in flow control using DTM technology and now offers the first flow control management DTM standardized for IIoT architectures based on FDT 3.0 for HART applications. HART users can deploy this new DTM and reap the benefits by using an FDT 3.0-based device management tool, such as PACTware 6.1, and can enjoy an IT/OT data-centric model by deploying an FDT Server, extending the data reach to mobile applications and the enterprise.”

I’ve had many conversations with Arlen Nipper of Cirrus Link, co-developer of MQTT, and Benson Hougland of Opto 22, early adopter of MQTT and Sparkplug, at the Inductive Automation Ignition Community Conference over several years about the demand for lightweight communications. OPC UA has a place in the toolbox, but many engineers desired a lightweight alternative. MQTT is a fast and lightweight transport protocol, but using it required engineers to specify their own payload technology. Enter Sparkplug. I call it a sort-of OPC-light (but people get mad at me for saying that).
Sparkplug has been developed as open source way for engineers to standardize their messages from IIoT devices to databases.
The Eclipse Foundation, one of the world’s largest open source software foundations, in collaboration with the Eclipse Sparkplug Working Group, announced that the Sparkplug 3.0 specification has been published as an International Standard. This publication is the outcome of a transposition of the specification through the Publicly Available Specification (PAS) transposition process offered by the ISO and IEC Joint Technical Committee (JTC 1) for information technology, a consensus-based, voluntary international standards group.
The International Organization for Standardization and International Electrotechnical Commission (ISO/IEC) are global organisations that facilitate the development of International Standards that support innovation, sustainability, and global trade. Sparkplug is an open software specification that enables mission-critical operational technology (OT) clients to use industry standards, including OASIS MQTT, to seamlessly integrate data from their applications, sensors, devices, and gateways with most Industrial Internet Of Things (IIoT) infrastructure. As a result, Sparkplug enables businesses to easily deploy complex, mission-critical IIoT systems in record time.
The PAS transposition process for reviewing and approving externally developed specifications at JTC 1 is neutral to all contributors and includes industry-wide participation. Going forward, the Sparkplug specification will also be known as ISO/IEC 20237. The Eclipse Foundation retains stewardship of the specification and intends to submit future revisions through the PAS transposition process.
The Sparkplug Working Group is simultaneously launching a product compatibility program for Sparkplug implementers. The program will ensure that Sparkplug-compatible products and implementations demonstrate a high degree of compatibility and interoperability.
Sparkplug provides an open and freely available specification for how Edge of Network (EoN) gateways or native MQTT-enabled end devices and MQTT Applications communicate bi-directionally within an MQTT Infrastructure. It is recognized that OASIS MQTT is used across a broad spectrum of application solution use cases and an almost indefinable variation of network topologies.
By design, the MQTT specification does not dictate a Topic Namespace or any payload encoding. However, as the IIoT and other architectures leveraging the publisher/subscriber model are adopted by device OEMs in the industrial sector, having different Topic Namespace and payload encoding can inhibit interoperability for the end customer. To that end, the Sparkplug specification addresses the following components within an MQTT infrastructure:
- Sparkplug defines an OT-centric Topic Namespace
- Sparkplug defines an OT-centric Payload definition optimised for industrial process variables.
- Sparkplug defines MQTT Session State management required by real-time OT SCADA systems.

I was invited to a presentation by a wireless technology provider called InterDigital. They wished to discuss the current state of global standard development especially in the wireless communication space.
My career has wandered through a maze of standard setting from chairman of the standards and technical committee of a trade association, to ASHRAE and UL committees, to sitting in on meetings of some international technical standard development, not to mention researching and writing about ISA standards. To draw from the movie title, I have witnessed the Good, the Bad, and the Ugly.
One thing I was taught early was the dance of the big companies in the industry joining standards development committees, their representatives being smart and nice people, and those same representatives doing all in their power by asking questions endlessly to slow or halt the standards development process. Or, best, would be like an early part of my engineering career which involved rewriting the specs to match our products.
This presentation led us from the past global economic strategies of companies to the current situation of nationalism—especially by China—where they try to do the same thing. Devise alternative standards, slow development of unfriendly standards, from the standpoint of Geopolitical strategies.
We know the benefits of standardization for all of us as users. The struggle is to implement enough despite that highly evolved dance so that we do benefit.
To recap things I’ve written about for more than 20 years:
- Interoperability
- Safety and Reliability
- Economies of Scale
- Innovation
- Open Market Access
What can I say. Get involved with standards where you can!

ODVA announced that process device profiles have been added to The EtherNet/IPTM Specification to provide automation practitioners with another critical tool to help optimize plant operations. Process device profiles provide a standard format for process variables and diagnostics across an array of devices for smoother vendor interoperability and easier DCS and PLC data integration from EtherNet/IP-enabled field devices.
Device profiles are available for Coriolis flow, electromagnetic flow, vortex flow, standard pressure, and scaled pressure devices. Process end users can now take advantage of EtherNet/IP devices with better communication of critical diagnostics such as NAMUR NE 107 status signals, and improved alignment with the Process Automation Device Information Model (PA-DIM).
EtherNet/IP process device profiles are made up of process measurement value objects for variables such as current pressure, level, flow, etc., process totalized value objects that track cumulative data totals such as total flow, and process device diagnostics objects that enable plant operators and maintenance personnel easier access to additional device and process status information. Process device profiles help convert sensor signals and actuator positions into valuable information that enables action to be taken to improve product quality and operational efficiency. Additionally, process device profiles can help evaluate the reliability of the measuring signal and aid in preventing plant shutdowns by identifying premature device failures.
As an example, the process totalized value object can track total device usage and device health can be inferred from the process measurement value and diagnostics objects. This allows users to shift from time-based maintenance to condition-based maintenance, potentially saving devices from unnecessarily being replaced during plant shutdowns while identifying other devices that are failing prematurely, which can reduce both unnecessary maintenance costs and potential downtime.
The EtherNet/IP process device profiles were designed with additional parameters and modified data types to better align with PA-DIM, which is a joint standard between FieldComm Group, ISA100 WCI, NAMUR, ODVA, OPC Foundation, PI, VDMA, and ZVEI. PA-DIM represents information from process devices in a standardized way for easier access.
In addition to exposing measurement values and the quality or status of those values, EtherNet/IP process device profiles can also simulate the measurement values. This enables critical safety functions such as partial stroke tests in valves to take place without interfering with the process data. The standard formatting of live process variables, data totals, and diagnostics that process device profiles provide will also increase vendor interoperability for end users given that the information will be the same across EtherNet/IP devices, regardless of vendor.
The addition of process device profiles adds to the process automation capability of EtherNet/IP, including the ability to use the Ethernet-APL physical layer. Ethernet-APL unlocks the advantages of commercially based industrial control hardware, an object-oriented foundation, and standard internet protocol compatibility including TCP/IP, HTTP, FTP, SNMP, and DHCP in process plants. Ethernet-APL is a combination of Single Pair Ethernet (IEEE 802.3cg-2019, 10BASE-T1L), engineered power, Intrinsic Safety (IEC 60079, 2-WISE), and Type A fieldbus cable (IEC 61158-2, for intrinsic safety) that is able to reach 1,000 meter distances and speeds of 10Mbit/s.
Additionally, EtherNet/IP supports process automation through NE 107 diagnostics, HART integration, and IO-Link integration. Further, ODVA is continuing to expand the EtherNet/IP ecosystem with the next generation of digitized device description files, including FDT, FDI, and xDS, to simplify integration into process asset management tools. Lastly, ODVA has also just released the availability of concurrent connections allowing for failsafe controller redundancy for the most critical of process applications.
“The introduction of process device profiles to EtherNet/IP is another critical step in meeting the full set of requirements of the process industries,” said Dr. Al Beydoun, President and Executive Director of ODVA. “EtherNet/IP process device profiles will help end users operate plants with superior yields, minimal downtime, and reduced costs. Additionally, better integration with PA-DIM will help process automation practitioners have the most valuable diagnostics and process variables available in both the control room and in the cloud to allow for enhanced insights and timely intervention measures for optimization of operations.”
EtherNet/IP process device profiles enable enhanced vendor interoperability, easier access to process variables and critical diagnostics such as NAMUR NE 107 status signals, and more seamless integration with PA-DIM. Additionally, process field device profiles will allow for simpler commissioning and enhanced asset monitoring and integration into higher level PLC, DCS, and cloud-based systems.
