IO-Link is an open standard that is globally supported by sensor and controls companies. The IO-Link master replaces a traditional analog input card and allows for a digital communication path to process sensors. The final result is a 100% digital path from a SCADA system, to PLC, to the field-mounted sensor.
IO-Link transmits a true digital process signal for more reliable and accurate signals than analog outputs.
With IO-Link, process sensors have the ability to transmit multiple sensor values. For example, ifm’s flow sensors can accurately transmit both flow and temperature measured values to the controller. This two-in-one capability reduces the need for multiple sensors and installation time.
The IO-Link master stores all parameters of the connected sensors. If a sensor must be replaced, the previous parameters are automatically written to the new sensor. Looking up the required sensor settings is not necessary.
No need to shut down the machine to make changes to sensor parameters. IO-Link allows remote parameterization without incurring unnecessary downtime. Parameters are easily changed via the plc.
IO-Link’s machine condition monitoring sensors are capable of tracking machine components, such as rolling element bearings, rotational turbulences, gear drive trains, etc. Predictive diagnostic sensor data is transmitted to the plc for early detection of critical failures. A proven solution for efficient predictive maintenance plans, IO-Link increases uptime and reduces maintenance costs.
IO-Link reduces the cost of analog functionality. The need for analog electronics in sensors or costly analog cards is eliminated.
