Smart devices can be fully utilized with IO-Link, paving the way for Industry 4.0 in automation technology. International standards focus on sustainably reducing interface costs and increasing efficiency, thereby lowering operational and maintenance expenses. Through standardized device description files (IODDs) and software tools, IO-Link sensors are appropriately configured and integrated.
IO-Link Sensor Applications
A typical example of an IO-Link application is a pressure switch. In a standard digital input, parameters of the pressure switch (such as switching point, alarm point, range, etc.) need to be adjusted manually using buttons on the device or through a USB port mounted on the device. With IO-Link devices, parameters can be adjusted via fieldbus and IO-Link communication.
A significant advantage of IO-Link devices is cost reduction. This is because IO-Link sensors are cheaper than standard sensors as they do not require push buttons and displays. Additionally, since standard M12 connectors are used, shielded cables are not necessary. Finally, unlike analog sensors that lack standards, IO-Link provides a wiring standard. They may use 2, 3, or 4-wire devices without a standard pin configuration for connections.
IO-Link Sensors and Innovations
IO-Link is a powerful yet simple protocol with broad industry support. There are many reasons to use IO-Link. An IO-Link sensor can provide significantly more information, configurability, and control almost anywhere a digital or analog sensor is used. From installation to operation and even maintenance of an automation system, IO-Link offers clear advantages over older solutions.
Whether setting up a new system or improving an existing one, IO-Link makes system installation and commissioning much less cumbersome compared to traditional machine setups. Standard connectors and cables reduce wiring complexity by eliminating the need for custom cables, connectors, or terminations. IO-Link’s parameterization simplifies new sensor configuration through standardized interfaces.
System Maintenance
IO-Link provides class-leading accessibility to the information required to maintain and maximize productivity within an automation network. IO-Link helps in identifying issues and potential process errors before they occur. For example, a sensor can automatically notify a PLC when its batteries are running low, allowing for maintenance and preventing machine downtime.
