14Safety Event Monitoring in third partymonitoring application
15Conclusions and future work1. Detailed safety information2. Safety levels improved3. Interoperable solution4. Safety information can be monitored by operator through embedded HMIs5. Safety information are published as events and can be integrated to any 3rd party monitoring application supporting WS-Eventing6. Future work is to develop new applications for utilising both safety and non-safety information
