IO-Link, the first standardized IO technology for communication with sensors and actuators, is a powerful point-to-point communication based on the long established 3-wire sensor and actuator connection. In addition to working smoothly in any control system, IO Link encompasses features that give you better diagnostics and can reduce wiring for your devices.
IO Link gateways allow you to connect multiple smart devices via one IP address, saving you time and money in installation time.
With IO-Link, you can reduce the time needed to fix a broken sensor. Say a sensor fails. If you have a large control system, it may take a while for that sensor to be found. Then when it is found, it may be difficult to reach. IO-Link gives you all the information you need to find and fix that sensor, including diagnostics of the process control system, remote programming, and even custom replacements that can be done automatically. Comtrol’s IO-Link Masters provide diagnostics about both sides of a given connection; you will get information about the IO Link connection that is running from the IO-link master to the end device and you will get detailed information about the industrial data protocol.
The ability to do remote parameterization can be combined with the support for remote diagnostics. Troubleshooting and fixing problems with a system can all be done remotely. Additionally, for those processes or systems where a “recipe” architecture is appropriate, IO-Link sensors and actuators can be remotely parameterized by the PLC in bulk via a simple selector switch or other minimal operator action. This powerful feature could be used to maximize quality or increase duty cycle via extended capital versatility without the burden of re-configuring each device one at a time.
IO Link is the further development of the existing, tried-and-tested connection technology for sensors and actuators, which can be easily integrated into a system network with existing and new industrial Ethernet installations. Come and see why you should implement IO Link in your system today.
