Today’s Presentation u u u Overview of OPC Data. Hub and Redundancy Overview of Tunneling Live Demo New Features in v 7. x Questions and Answers

OPC Data Hub Functionality Overview http: //www. softwaretoolbox. com/opcdatahub

Redundancy Overview u Where is it used? u u u Mission critical systems Single point of failure exists Why is it used? u u Increase system reliability and availability Limit interruptions in sending and receiving data

Levels of Redundancy u Device u u Server u u Redundant connections between server and multiple devices Redundant connections between client and multiple servers Client u Redundant client connections

Types of Redundancy u Cold u u Application will only connect to one server at a time If connection to primary server is lost, connection will be established with secondary

Types of Redundancy u Hot u u Application tries to maintain a connection to both primary and secondary servers at all times Callback is initialized for both servers

Redundancy and the OPC Data. Hub u Gamma u u Engine u u C-based scripting language Dynamic environment Event driven Object oriented Redundancy scripts u u Switchover. g Enable. OPCConnection. g

Expanding Redundancy with the Data. Hub u Combine all features of the Data. Hub to make most of your data u u u SMS/Email alerts when fail over occurs Bridge data between domains Log to a Database Data Tunneling Data Aggregation Easy set-up

What is Tunneling? OPC Tunneling u u Moving OPC Data via simple TCP/IP port connection Eliminating DCOM and Expanding Data Transport Choices Computer #1 Computer #2

3 Steps to Tunneling with OPC Data. Hub u u u Step 1: Connect Master to OPC Server Step 2: Connect Master to Slave Step 3: Connect OPC Client to Slave

OPC Tunneling Why Tunnel? u u u u No DCOM! No Remote Procedure Calls (RPC) Handles Network Interruptions Handles Low-bandwidth networks Improve System Performance & Reliability Reduce Network Traffic Remove Firewall Issues Connecting to Non-Windows Systems

Live Demonstration u Hot Redundancy u u u Primary: Tunnel to Remote OPC Server Secondary: Local OPC Server Cold Redundancy u u Primary: Local TOP Server v 5 Secondary: Local TOP Server v 4
