  2. Overview • Requirements of Customers and Manufacturers • WhatisOSSDe all about? • Whya newsafecommunicationprofile? • Whatdidweachieve so far? • What'snext? IO-Link Safety Status

  3. Manufacturer's Situation Safetycontroller(FS-PLC) FS-PLC Fieldbus / FSCP Remote I/O with FS modules FS-DI Redundant signallines FS = functionalsafety PLC = programmablelogiccontroller e.g. Emergency Stop IO-Link Safety Status

  4. Customer's Situation • Machinemanufacturerdecides on fieldbustobeuseddepending on deploymentcase • Thus, specificdevicesforeachfieldbuswith separate sparesinventory, versionmaintenanceandservicearerequired • Thus, high degreeofpersistencetostaywith "classic" interfaces such as OSSD, 4 to 20 mA, and etc. on "remote IO" fielddevices, sincetheyareindependentfromfieldbus • However: noconnectionto Internet-of-Things (IoT) andIndustry 4.0 • Numerousnewapplications: (see "Smart Manufacturing")- New sensortechnologies, e.g. strain, torque, pressure, multi-sensing, and etc.- More measuringsensors, e.g. objecttypes, distance- Mechatronics, e.g. combinationssensors/actuators • Progressive miniaturization IO-Link Safety Status
