How IO-Link Sensors With Condition Monitoring Features Work With PLCs

As manufacturers continually look for ways to maximize productivity and eliminate waste, automation sensors are taking on a new role in the plant. Once, sensors were used only to provide detection or measurement data so the PLC could process it and run the machine. Today, sensors with IO-Link measure environmental conditions like temperature, humidity, ambient …

IO-Link Event Data: How Sensors Tell You How They’re Doing

I have been working with IO-Link for more than 10 years, so I’ve heard lots of questions about how it works. One line of questions I hear from customers is about the operating condition of sensors. “I wish I knew when the IO-Link device loses output power,” or, “I wish my IO-Link photoelectric sensor would …

IO-Link Benefits in Robotic Weld Cell Tooling

By Scott Barhorst Working previously as a controls engineering manager in robotic welding, I have seen some consistent challenges when designing robotic weld cell systems. For example, the pre-engineered-style welding cells I’ve worked with use many types of tooling. At the same time, space for tooling and cabling is limited, and so is the automation …

IO-Link: End to Analog Sensors

With most sensors now coming out with an IO-Link output, could this mean the end of using traditional analog sensors? IO-Link is the first IO technology standard (IEC 61131-9) for communications between sensors and actuators on the lower component level. Analog sensors A typical analog sensor detects an external parameter, such as pressure, sound or …

What is IO-Link? A Simple Explanation of the Universal Networking Standard

Famed physicist Albert Einstein once said, “If you can’t explain it simply, you don’t understand it well enough.” When the topic of IO-Link comes up, whether a salesperson or technical expert is doing the explaining, I always find it’s too much for the layman without a technical background to understand. To simplify this complex idea, I’ve created an analogy to something we use in our everyday lives: highways.   Prior to the Federal Highway Act …

IO-Link Wireless – IO-Link with Even Greater Flexibility

In a previous blog entry, I discussed IO-Link SPE (Single-Pair Ethernet). SPE, in my opinion, has two great strengths compared to standard IO-Link: cable length and speed. With cable lengths of up to 100 meters and speed of 10 Mbps, compared to 20 meters and max baud rate of 230.4 Kbps, what could be out …

Use IODD Files with IO-Link for Faster, Easier Parameterization

Using IO-Link allows you to get as much data as possible from only three wires. IO-Link communicates four types of data: device data, event data, value status, and process data. Value status data and process data are constantly sent together at a known rate that is documented in each device’s manual and/or data sheet. Device …

IO-Link Simplifies Connectivity on Robotic End-Effectors

In my last two blogs, Rise of the Robots: IO-Link… and Realize Productivity Gains with Smart Robotic Tooling , I shared how implementing IO-Link and incorporating pneumatic and electric smart grippers can help maximize your use of robotics in your applications. In this blog, I will discuss how you can get more from your robots …
