IO Link Masters IFM photo

IFM I/O Link master is a special gateway for connection IO-Link devices. It can connect up to eight different devices to a single outlet (sensors, modules, valves, etc.). Through IO link master all data and parameters transmits to control systems.

The process of intellectualization of sensors is still ongoing; more and more new standards for data exchange between devices are emerging. This is precisely what the IO-Link Protocol became. Leading manufacturers of sensors and control systems have developed it. The result is a fieldbus-independent interface for automation. It provides the user with a point-to-point connection without complex addressing.

IO-Link allows sensors to transmit information about their status and events that have occurred, including allowing the settings of these sensors to be changed remotely. The IFM company is directly related to the creation of IO-Link and related devices, such as IFM IO-Link master modules, which we will talk about in more detail today.  

Overview of IO-Link Masters by IFM

The IO-Link master replaces the traditional analog input card with a digital communication link between the master and the device. Up to 8 IO-Link devices, such as sensors, valves, and I/O modules, can be connected to one master, depending on the master configuration. The master transfers machine data, process parameters, and diagnostic information to the PLC controller or directly to a higher-level Industrial IoT (IIoT) control system.

IFM has created the IO-Link Master series to help realize Industry 4.0. IFM is consistently promoting its IO-Link Master series as the fourth industrial revolution evolves.

Many of the benefits of Industry 4.0 and IIoT overlap with those of IO-Link. IFM currently has six IO-Link masters with a choice between three separate protocols: EtherNet/IP, Modbus TCP, and PROFINET IO.

IFM's IO-Link Master products are, simply put, “enabling the development of Industry 4.0 and IIoT.” The integration of IO-Link Master with sensors and actuators at the field level provides point-to-point communication all the way to the upper levels of the enterprise resource planning (ERP) data pyramid.

Industry 4.0 is actually the fourth industrial revolution. The first industrial revolution was the use of water and steam power, the second was the use of electricity, followed by the digital revolution. The goal of Industry 4.0 is to fully integrate the communication process used in manufacturing to improve the efficiency of enterprises through IIoT, industrial automation, data exchange, and manufacturing technologies.

There are several series of IFM IO Link master for different applications:

  • Filed mountable for industrial automation
  • Field mountable for high pressure cleaning
  • DIN rail mountable for control cabinets

IO-Link Technology

In the fast-paced industrial technology and factory automation world, IFM is committed to innovation, efficiency, and resource conservation. We strive for universal protocols and the development of interconnection between ecosystems.

IFM is a founding member of the IO-Link consortium. This group works with industry leaders to advance technology and integration, maintain quality standards, conduct workshops, and more. The consortium has more than 250 members and continues to grow.

IO-Link is a global communications standard (IEC 61131-9) that revolutionizes how you connect and interact with digital sensors and actuators. Using wired or wireless configurations, this technology solves integration problems and allows devices to exchange rich data sets seamlessly.

In addition to providing fast and cost-effective communication between devices to reduce downtime, IO-Link offers other benefits.

Data storage
IO-Link master module can store up to 2 KB of parameters that affect the operation of the sensor or actuator. If a sensor needs to be replaced, the IO-Link master quickly and automatically writes the parameters of the replaced IO-Link sensor to the new sensor. When the sensor needs to operate with new parameters, this information can be sent remotely and is automatically updated. After commissioning, format, or recipe changes, no manual intervention is required to restart the equipment. This saves valuable time and minimizes the chance of human error.

Remote configuration and monitoring
Device and sensor parameters can be easily changed remotely as needed, saving valuable time in production, such as during product changes (moving from small bottles to large bottles on a production line). This also makes it easier to reconfigure devices in hard-to-reach places. Sensor outputs and status alerts can be monitored remotely in real time, helping you quickly identify and resolve problems before they cause downtime.

Diagnostic capabilities
Intelligent sensors equipped with IO-Link can report their status via an IO-Link master to the PLC. Before processes stop, you will immediately know whether the sensor needs replacement, requires maintenance, or has an error. This allows you to optimize machine maintenance schedules and diagnose problems with a specific sensor without shutting down an entire line or equipment.

Cost savings
In addition to saving time, which results in a higher return on investment, IO-Link also reduces overall system costs. The sensors do not require an Ethernet interface; they rely on the IO-Link communication interface, which is much more cost-effective. Because IO-Link does not require unique or complex wiring, material costs are also lower. You can use the same cost-effective, unshielded cables for conventional discrete I/O to make wiring inexpensive and straightforward. IO-Link also eliminates the need for analog cards. This also reduces the wires you need to purchase and store in stock.

Overview of the production workshop
IO-Link acts as the eyes and ears of your plant, providing never-before-seen process information that allows you to make decisions to reduce downtime. For example, if a sensor is short, IO-Link alerts you, pinpoints the exact location of the sensor, and guides you straight to it, providing real-time diagnostic information. Hence, you know what's causing the problem.

Vendor independence
IO-Link is a vendor-independent technology that allows IO-Link devices to be used in any standard industrial fieldbus environment.
