6. 6
−Currently not so much present on Automation level
−Widely used in IT-/Office-environment
−IoT / Industry 4.0: IT/Office needs data from Shopfloor
• Predictive Maintenance / Condition Based Monitoring
• Production Cost (energy, raw material, water, scrap, etc.)
• Increase of Quality and Effectiveness
• Reduction of Cost and Equipment Downtime
• Order Information
• Compliance / Governmental Reporting

9. What is OPC?

10. −Standarized protocol to exchange
data between different
communcation partners
• Back then only on shopfloor
• Today also for secure
communication from shopfloor to
topfloor
−Client/Server architecture

What is OPC?
Shopfloor

11. ▪ Communication via Microsoft DCOM
▪ Only for Windows-OS
▪ Access only via Windows-Components
▪ No VPN-Access
▪ No direct communication through Firewalls
OPC S er ver : Classic (DA) an d Un ified Ar ch itectu r e (UA)
OPC Insight
OPC Classic OPC UA (Unified Architecture)
▪ Communication via TCP/IP
▪ Platform-independent
▪ Encryption/Access via Webstandard
(RSA, x509) and User Authentication
▪ Enables Communication across Domain-borders
(WAN, Internet)

12. Communication exchange not
only of data, but also of
complex information models
(metadata, instances) and
thus enables interoperability
on a semantic level

13. • Binary with UA-TCP:
• Optimized for Performance
• Thorughout Protocol
• Single TCP-Port used for Communication
• opc.tcp-Protocol
• Webservice (XML-SOAP):
• „Firewall friendly“
• XML-Structure through https-Protocol
• Easier for Java or dotnet-Environments
• By default single-port 443 needs to be unlocked
• Hybrid (UA-Binary via HTTPS)
• Advantages of both worlds (firewall friendly binary coded
implementation in https-frame)
• By default single-port 443
