SpeedMonitor TimerRelays What does Safety normally look like? • Safety Relays within the cabinet • Safety application by discrete wiring PLC I/O Servo Additional DI/DO module Extra wiring of safe sensors Extra wiring required to control safe actuators SafetyRelays Extra speed monitor for safe motion control functions Timer Relays for synchronous shutdown
Reduced Wiring Benefit1 StandardDI SafetyRelays • Additional Wiring • Failure of standard I/O’s can affect safety. • Data of safety and standard I/O’s transfered via the same communication network. • No Unnecessary Wiring
Decreased Response Time Benefit2 Speed Monitor > 80 ms32 mm < 7 ms0,25 mm Relays • Response time of several tens of miliseconds • Latency induced by the relay • Response time less than 10 ms • Significantly reduces the energy delivered and thus the danger. • Reduces safety distances
Elimination of Setup Errors Benefit3 ??? SLS Limit 10A? • Significant risk of errors during maintenance • Wrong Parameterization • Poor positioning of switches • Using wrong power class • Automatic Parameterization • Consistent configuration through configuration files (EDS) • Traceability of maintenance(registration, password protection)
Intelligent Safety Features Benefit4 • Ease of implementation of safety features • Control of all features via communication bus • Fully integrated and secure settings • Implementing safety features is complex • Function control require many wires • Large number of parameters difficult to configure
Safety market overview • Available Safety Protocols • ProfiSafe islimitedto Profibus and Profinet • CIPSafety islimitedto Rockwell protocols and SERCOS • Safety EtherCAT islimitedto EtherCAT • Safety Net p is aproprietaryprotocol from PILZ • openSAFETYis opened and available for any transport protocol • These protocol are proprietary or limited to certain Fieldbus! • These technologies are NOT compatible with each other !
openSAFETY is open and independent • Independence of underlying hardware, software and networking technologies • Totally independent from technical and legal aspects
openSAFETY market • openSAFETY is already operational on: • EtherNet/IP • Modbus TCP/IP • POWERLINK • SERCOS III • PROFINET • openSAFETY covers 91% of Industrial Ethernet market !
openSAFETY for the component manufacturer • One time development investment • same safety standard for all fieldbuses • Reduced development time • Certified openSAFETY stack available • Investment security • legal and technical independence • open source protocol stack • Easy certification • TÜV certified conformance test • guaranteed interoperability
openSAFETY for the end user • One safety standard for your entire production plant • Cost reduction • Less down-time • Higher productivity • Easy maintenance
