Who Moved My Data? Part 2: Insourcing Condition Monitoring

In my previous blog on this topic, “Who Moved My Data? Outsourcing Condition Monitoring,” I established the case for condition-based monitoring of critical assets to ensure a reduction in unplanned downtime. I also explored the advantages and disadvantages of outsourcing condition monitoring from critical assets. Here I discuss the do-it-yourself (DIY) approach to condition monitoring and explore its advantages and disadvantages.

Understanding the DIY approach

Now, let me be clear to avoid any confusion, when I refer to “do it yourself,” I don’t mean literally doing it yourself. Instead, this is something you own and customize to fit your applications. It may require a fair amount of input from your maintenance teams and plants. It’s not a one-day job, of course, but an ongoing initiative to help improve productivity and have continuous improvements throughout the plant.

Advantages and disadvantages of DIY condition monitoring (insourcing)

Implementing the solutions for continuous condition monitoring of critical assets by yourself has many advantages, along with some disadvantages. Let’s review them.

Advantages of insourcing (DIY) condition monitoring:

    1. Data ownership: One of the greatest benefits or advantages of implementing the DIY approach to condition monitoring is the control it gives you over data. You decide where the data lives, how it is used, and who has access to it. As I emphasized in my previous blog and numerous presentations on this topic, “Data is king” – a highly valuable commodity.
    2. Flexibility and customization: Of course, the DIY solution is not a one-size-fits-all approach! Instead, it allows you to customize the solution to fit your exact needs – the parameters to monitor, the specific areas of the plant to focus on the critical systems and the method of monitoring. You choose how to implement the solutions to fit your plant’s budget.
    3. Low long-term costs: As you own the installations, you own the data and you own the equipment; you don’t need to pay rent for the systems implemented through outsourcing.
    4. The specification advantage: As a plant or company, you can add condition monitoring features as specifications for your next generation of machines and equipment, including specific protocols or components. This allows you to collect the required data from the machine or equipment from the get-go.

Disadvantages of insourcing (DIY) condition monitoring:

    1. High upfront cost: Implementing condition monitoring with a data collection system may involve higher upfront costs. This is because there is a need to invest in data storage solutions, engage experts for condition monitoring implementation (typically from an integration house or through self-integration), and employ developers to create or customize dashboards to fit user needs.
    2. Limited scalability: collecting more data requires additional storage and enhanced analytics capabilities, especially when transitioning from condition-based maintenance to predictive analytics. Designing your own solution with limited budgets may hamper the scalability of the overall system.
    3. Infrastructure maintenance: This is another area that requires close attention. Whether the infrastructure is located on-premises, centralized, or in the cloud, the chosen location may require investments in manpower for ongoing maintenance.

Another point to emphasize here is that opting for a DIY solution does not preclude the use of cloud platforms for data management and data storage. The difference between insourcing and outsourcing lies in the implementation of condition monitoring and related analytics – whether it’s carried out and owned by you or by someone else.

Strategic decision-making: beyond cost considerations

The final point is not to make outsourcing decisions solely based on cost. Condition-based monitoring and the future of analytics offer numerous advantages, and nurturing an in-house culture could be a great source of competitive advantage for the organization. You can always start small and progressively expand.

As always, your feedback is welcome.

Understanding Machine Safety: The Power of Risk Assessments

My last blog post was about machine safety with a focus on the different categories and performance levels of machine safety circuits. But I just briefly touched on how to determine these levels. By default, we could design all equipment with the highest-level category and performance levels of safety with an abundance of caution, but this approach could be extremely expensive and not the most efficient.

Enter the important concept of risk assessments which enable us to identify, evaluate, and prioritize potential hazards and risks associated with specific activities, processes, or systems. Whether it’s in the domain of occupational health and safety, environmental health, or product safety, risk assessments can guide us toward ensuring the safety of those who may interact with these hazards. This process involves the following well-defined series of steps, including hazard identification, risk analysis, risk evaluation, and risk control.

Hazard identification

Hazard identification involves identifying potential hazards and risks associated with the activity, process, or system you’re assessing. This can be done using a variety of methods, such as observing the process, reviewing relevant documentation, or consulting with experts.

Looking at Figure 1, what are the hazards? They are pinch points from the robot, crush points from the robot, and shock or burn from the end effector. Another potential hazard that cannot be determined by the picture is the speed at which the pallet is traveling. Identifying the hazards is an important step because you cannot mitigate a risk without properly identifying it first.

Risk analysis

Analyzing the likelihood and severity of the identified hazards and risks is key to risk analysis. Various methods, including the use of historical data, simulations, or mathematical models can facilitate this.

Risk evaluation

Risk evaluation involves assessing the significance of the identified hazards and risks by considering their exposure, severity of injury, and the likelihood of avoiding that hazard. In this example, the robot could potentially crush you, making it a high severity. When the robot operates at full speed, the likelihood of avoiding it is low. In the case of an automated cell, exposure may be infrequent, but maintenance on the robots will still be necessary.

Risk control

Risk control encompasses the identification and implementation of measures to prevent or mitigate the identified hazards and risks. This can include redesigning the process, implementing safety controls, or providing training to employees.

Again, the category and performance levels of safety controls required are based on the defined risks.

In our robot example above, the first control we would implement is an enclosure around the robot to prevent people from getting close to the hazard. We cannot have an enclosure without some method for entering the enclosure, so we will add a door to the enclosure. It’s the door’s interaction with the cell that must have the appropriate category and performance level based on our evaluation. When the door is open, we will limit the operation and speed of the robot. We can use a teach pendant with a “dead man” switch that requires the person inside the cell to hold it while operating the robot at a slower speed. This will decrease the likelihood of a hazard. Additionally, we would need to have a method for the pallet to enter in and out of the enclosure.

Risk assessments should be conducted with a group of qualified people which may include safety personnel, engineers, managers, and potentially end users familiar with the automation process. The risk assessment process is iterative in that it may need repeating if new hazards or risks are identified, or if changes are made to the activity, process, or system being assessed.

Have a safe day!

From Wired to Wireless Automation Advancements in Automotive Manufacturing

Looking back, the days of classic muscle cars stand out as a remarkable period in automotive history. Consider how they were built, including every component along the assembly line connected through intricate wiring, resulting in prolonged challenges related to both wiring and maintenance. Advancements in technology led to the introduction of junction blocks, yet this didn’t entirely solve the persistent problems associated with time and connections.

In the mid-2000s, a collaborative effort among multiple companies resulted in the development of the IO-Link protocol. This protocol effectively tackled the wiring and maintenance issues. Since its inception, IO-Link has continued to progress and evolve.

In 2023, we’re taking the next step with a wireless IO-Link master block.

In modern manufacturing, the process involves using independently moving automated guided vehicles (AGVs), also known as skillets. These AGVs are responsible for performing various tasks along the production line before completing their circuit and returning to their initial position. Initially, when these AGVs were integrated, each of these skillets was equipped with a programmable logic controller (PLC), which incurred significant expenses and extended the setup time. Additionally, the scalability of this system was limited by the available IP addresses for the nodes.

Demand for wireless IO-Link blocks

In recent years, there has been a growing demand for wireless IO-Link blocks. Now, a solution to meet this demand is available. The wireless IO-Link block works in a manner similar to the existing current blocks but without the need for a PLC, simplifying wiring and using existing Wi-Fi infrastructure.

Imagine a conveyor scenario where numerous AGVs follow a designated path, each with a hub attached. The setup would look something like this: up to 40 hubs communicating simultaneously with a central master. Each hub has the capacity to accommodate up to eight connected devices, resulting in a total of 320 distinct IO points managed by a single IO-Link master.

Communication among these blocks employs a protocol akin to that of a cell phone. As an AGV transitions from one master hub to another, it continues to transmit its data. Within each hub, an identity parameter not only designates the specific hub but also identifies the associated skillets and the location within the manufacturing plant.

Transitioning to a wireless system leads to a substantial reduction in your overall cost of ownership. This includes decreased setup times, simplified troubleshooting, lower maintenance efforts, and a reduced need for spare parts.

We are in an exciting time of technological advancement. Make sure you are moving alongside us!

Comparing IO-Link and Modbus Protocols in Industrial Automation


In the realm of industrial automation, the seamless exchange of data between sensors, actuators, and control systems is critical for optimizing performance, increasing efficiency, and enabling advanced functionalities. Two widely used communication protocols, IO-Link and Modbus, have emerged to facilitate this data exchange. In this blog, I’ll analyze the characteristics, strengths, and weaknesses of both protocols to help you choose the right communication standard for your industrial application.

    • Industry adoption:

   – IO-Link adoption is growing in industrial automation, especially in applications that demand high performance, advanced capabilities, and support of IIOT.

   – Modbus has been widely adopted over the years and remains prevalent, especially in legacy systems or simpler applications.

Both IO-Link and Modbus are valuable communication protocols in industrial automation, each with its strengths and weaknesses. IO-Link excels in high-performance applications that demand real-time data exchange, bidirectional communication, and advanced diagnostics. On the other hand, Modbus remains a viable option for simpler systems where ease of implementation and broad device support are essential.

The choice between IO-Link and Modbus depends on the specific requirements of your industrial application, the level of complexity needed, and the devices you plan to use. Understanding the capabilities of each protocol will empower you to make an informed decision, ensuring your communication system optimally supports your automation needs.

Revisiting the Key Points of IO-Link

IO-Link is a communication protocol for use in industrial automation systems to connect sensors and actuators to a central control system. It provides a standardized interface for the communication and configuration of devices, allowing for seamless integration and easy parameterization.

Here are some key points about IO-Link

    • Communication: IO-Link uses a point-to-point serial communication link between the IO-Link master and the IO-Link devices (sensors or actuators). Typically, the communication occurs over a standard 3-wire sensor cable.
    • Master/device architecture: The IO-Link system consists of an IO-Link master, which serves as a gateway between the IO-Link devices and the control system. The IO-Link master can connect to multiple IO-Link devices in a network.

Using MQTT Protocol for Smarter Automation

In my previous blog post, “Edge Gateways to Support Real-Time Condition Monitoring Data,” I talked about the importance of using an edge gateway to gather the IoT data from sensors in parallel with a PLC. This was because of the large data load and the need to avoid interfering with the existing machine communications. In this post, I want to delve deeper into the topic and explain the process of implementing an edge gateway.

Using the existing Ethernet infrastructure

One way to collect IoT data with an edge gateway is by using the existing Ethernet infrastructure. With most devices already communicating on an industrial Ethernet protocol, an edge gateway can gather the data on the same physical Ethernet port but at a separate software-defined number associated to a network protocol communication.

Message Queue Telemetry Transport (MQTT)

One of the most commonly used IoT protocols is Message Queue Telemetry Transport (MQTT). It is an ISO standard and has a dedicated software Ethernet port of 1883 and 8883 for secure encrypted communications. One reason for its popularity is that it is designed to be lightweight and efficient. Lightweight means that the protocol requires a minimum coding and it uses low-bandwidth connections.

Brokers and clients

The MQTT protocol defines two entities: a broker and client. The edge gateway typically serves as a message broker that receives client messages and routes them to the appropriate destination clients. A client is any device that runs an MQTT library and connects to an MQTT broker.

MQTT works on a publisher and subscriber model. Smart IoT devices are set up to be publishers, where they publish different condition data as topics to an edge gateway. Other clients, such as PC and data centers, can be set up as subscribers. The edge gateway, serving as a broker receives all the published data and forwards it only to the subscribers interested in that topic.

One client can publish many different topics as well as be a subscriber to other topics. There can also be many clients subscribing to the same topic, making the architecture flexible and scalable.

The edge gateway serving as the broker makes it possible for devices to communicate with each other if the device supports the MQTT protocol. MQTT can connect a wide range of devices, from sensors to actuators on machines to mobile devices and cloud servers. While MQTT isn’t the only way to gather data, it offers a simple and reliable way for customers to start gathering that data with their existing Ethernet infrastructures.

Automated Welding With IO-Link

IO-Link technologies have been a game-changer for the welding industry. With the advent of automation, the demand for increasingly sophisticated and intelligent technologies has increased. IO-Link technologies have risen to meet this demand. Here I explain the concepts and benefits of I-O Link technologies and how they integrate into automated welding applications.

What are IO-Link technologies?

IO-Link technologies refer to an advanced communication protocol used in industrial automation. The technology allows data transfer, i.e., the status of sensors, actuators, and other devices through a one-point connection between the control system and individual devices. Also, it enables devices to communicate among themselves quickly and efficiently. IO-Link technologies provide real-time communication, enabling continuous monitoring of devices to ensure optimal performance.

Benefits of IO-Link technologies

    • Enhanced data communication: IO-Link technologies can transfer data between the control system and sensors or devices. This communication creates an open and transparent network of information, reflecting the real-time status of equipment and allowing for increased reliability and reduced downtime.
    • Cost-efficiency: IO-Link technologies do not require complicated wiring and can significantly reduce material costs compared to traditional hardwired solutions. Additionally, maintenance is easier and more efficient with communication between devices, and there is less need for multiple maintenance employees to manage equipment.
    • Flexibility: With IO-Link technologies, the control system can control and monitor devices even when not attached to specific operator workstations. It enables one control system to manage thousands of devices without needing to rewrite programming to accommodate different machine types.
    • Real-time monitoring: IO-Link technologies provide real-time monitoring of devices, allowing control systems to monitor failures before they occur, making it easier for maintenance teams to manage the shop floor.

How are IO-Link technologies used in automated welding applications?

Automated welding applications have increased efficiencies and continuity in processes, and IO-Link technologies have accelerated these processes further. Automated welding applications have different stages, and each step requires real-time monitoring to ensure the process is efficient and effective. IO-Link technologies have been integrated into various parts of the automated welding process, some of which include:

    1. Positioning and alignment: The welding process starts with positioning and aligning materials such as beams, plates, and pipes. IO-Link sensors can detect the height and gap position of the material before the welding process begins. The sensor sends positional data to the control system as a feedback loop, which then adjusts the positioning system using actuators to ensure optimal weld quality.
    2. Welding arc monitoring: The welding arc monitoring system is another critical application for IO-Link technologies. Monitoring the arc ensures optimal weld quality and runs with reduced interruptions. IO-Link temperature sensors attached to the welding tip help control and adjust the temperature required to melt and flow the metal, ensuring that the welding arc works optimally.
    3. Power supply calibration: IO-Link technologies are essential in calibrating the power output of welding supplies, ensuring consistent quality in the welding process. Detectors attached to the power supply record the energy usage, power output and voltage levels, allowing the control system to adjust as necessary.
    4. Real-time monitoring and alerting: Real-time monitoring and alerting capabilities provided by IO-Link technologies help to reduce downtime where machine health is at risk. The sensors monitor the welding process, determining if there are any deviations from the set parameters. They then communicate the process condition to the control system, dispatching alerts to maintenance teams if an issue arises.

Using IO-Link technologies in automated welding applications has revolutionized the welding industry, providing real-time communication, enhanced data transfer, flexibility, and real-time monitoring capabilities required for reliable processes. IO-Link technologies have been integrated at various stages of automated welding, including positioning and alignment, welding arc monitoring, power supply calibration, and real-time monitoring and alerting. There is no doubt that the future of automated welding is bright. With IO-Link technologies, the possibilities are endless, forging ahead to provide more intelligent, efficient, and reliable welding applications.
