OPC UA for Devices
• Better Performance
• Less Complexity
• More Stable - Fewer Points of Failure
• Less Expensive (no OPC Server)
• Faster Commissioning Time (no mapping of
process variables)
• Reduced Chances of Error
• More Secure (authentication and encryption)
• Windows and non-Windows Clients
Advantages
IoT (Internet of Things)
Hardware
Ethernet / WLAN / Bluetooth
All about connected devices
IoT = Industry 4.0 = M2M
Industry 4.0 needs OPC UA to enable integration between devices and systems
OPC UA to play a huge role in the Internet of Things
Software Integration
Take Away - OPC UA
• Information Model
• Open Standard
• Secure
• Scalable
• Multi-Platform
• Web and Cloud Friendly
OPC UA, the “glue” for bringing applications together
Take Away – HMI/SCADA Software
• Better organization
• More relevant information
• Reduce development time and cost • screen reuse
• parallel development
• engineers and designers
• Interoperability
• New capabilities
Using an Information Model in Remote Monitoring Solutions:
Take Away - IoT / Industry 4.0
• Embedded Devices
• WLAN / Bluetooth / Ethernet
Internet of Things is Here
Industry 4.0
• OPC UA Servers on Devices / Chips
• OPC UA to provide software integration
