I remember my introduction to industrial “fieldbus” technology that came even before I became an editor with Control Engineering. That was in the 90s. Another indication of the maturity of the automation and control market lies in this announcement from the EtherCat Technology Group.
I love press releases. The writers are not bashful about proclaiming their virtues. I’m sure there are a couple of others who would contest some of the proclamations. But, this network did bring Ethernet early on and works well with motion control more so than some others.
Beckhoff Automation, a pioneer in automation solutions, proudly commemorates the 20th anniversary of EtherCAT, the groundbreaking industrial Ethernet ystem that transformed the world of industrial networking. Since its introduction at Hannover Messe in 2003, EtherCAT has emerged as the leader in speed, flexibility and openness, solidifying its position in the global market through its reliability and continuous technical advancements. Today, EtherCAT remains an open IEC standard and empowers companies across industries to leverage its key technological advantages.
EtherCAT combines the standard Ethernet protocol with the reliability, performance and stability required for industrial communication, delivering significant advantages:
Fast communication and nanosecond synchronization via distributed clocks
Reduce CPU loads by up to 30%
Flexible topology: tree, star, drop, line, circle, etc. – or any combination of these is possible
Automatic addressing of nodes
Comprehensive and highly localized diagnostics
Noise immunity and high bandwidth
No switches are necessary, masters only need an Ethernet port, and sub-devices can use a variety of ESC chips – all of which keep expenses near or less than legacy fieldbus costs.
While I see companies that are predominantly American rushing to capture open technology initiatives and make them as proprietary as possible, here is another predominantly German initiative pushing for using standards to move manufacturing technology forward.
This news came to me indirectly from the PI (Profibus and Profinet standards organization). Check it out. Do you find this potentially useful?
What is MTP?
By now, we all know OPC UA is really good at supporting the use-cases for not only horizontal integration like machine to machine, but also vertical integration like device to cloud. Now, most recently, OPC UA is being applied to those industries considered to be process control or hybrid industries with factory automation.
Rather than have every single I/O point controlled by one large distributed control system (DCS), MTP seeks to modularize the process into more manageable pieces. The point is to construct a plant with modular equipment to ease integration and allow for better flexibility should changes be required. With the help of a Process Orchestration Layer (POL), MTP-enabled equipment can “Plug & Operate” reducing the amount of time to commission a process or make changes to that process… pretty cutting-edge stuff.
The POL is the superordinate software into which an MTP file is imported. When an MTP file is imported into the POL, offline service engineering (orchestration) is performed along with communication configuration (OPC UA). Note: if recipe/batch engineering is applicable, MTP utilizes the ISA 88 standard here. The next step is an Orchestration Test (“Plug”) and then to begin (“Operate”). It is truly “Plug & Operate”.
Why should you care?
MTP files describe Equipment Assemblies. These are individual automated units providing the functionality to realize a step in a process. They have their own mechanical equipment, sensors, actuators, and controller. A great example would be skid integration. Here, an end-user can quickly integrate skids into their plant DCS to reduce engineering effort. The MTP file describing the skid is employed to shorten the time-to-market. According to ZVEI the benefits from first pilot projects can be summarized as follows:

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.

Betacom recently talked with me about its new Private 5G Ecosystem. To me the term ecosystem implies a (usually) proprietary software platform where a company hopes to recruit a critical mass of companies to commit. This ecosystem looks more like what I’ve been taught to be more resilient and perhaps useful—loosely coupled. And certainly private 5G networks are finally coming to fruition after a long gestation.
Betacom and its partners, including Google Cloud, Intel, Ingram Micro Inc. and Qualcomm Technologies, are collaborating to design, validate and deploy solutions for a variety of enterprise applications – setting the stage for the next phase of economic and business evolution driven by connectivity, automation, artificial intelligence, machine learning and real-time data. (I apologize for allowing almost every buzz word into the article.)
The partner initiative will help to expedite solutions through open collaboration aimed at building an ecosystem of pre-tested Industrial IoT devices and applications, integrated with mobile edge compute, supported by established system integrators and powered by private 5G.
The ecosystem currently includes 15 companies from across the technology spectrum – each with unique domain and industry expertise. Charter members include:
