Expanding your Data Redundancy Options Presenters: Renee Sikes, Product Support Engineer Win Worrall, Product Support Engineer and Developer OPC DataHub Redundancy Options Combining redundancy with other DataHub features
2
Today’s Presentation Overview of OPC DataHub and Redundancy Overview of Tunneling Live Demo New Features in v7.x Questions and Answers
3
OPC Data Hub Functionality Overview http://www.softwaretoolbox.com/opcdatahub
4
Redundancy Overview Where is it used? Mission critical systems Single point of failure exists Why is it used? Increase system reliability and availability Limit interruptions in sending and receiving data
5
Levels of Redundancy Device Redundant connections between server and multiple devices Server Redundant connections between client and multiple servers Client Redundant client connections
6
Types of Redundancy Cold Application will only connect to one server at a time If connection to primary server is lost, connection will be established with secondary
7
Types of Redundancy Hot Application tries to maintain a connection to both primary and secondary servers at all times Callback is initialized for both servers
8
Redundancy and the OPC DataHub Gamma C-based scripting language Engine Dynamic environment Event driven Object oriented Redundancy scripts Switchover.g EnableOPCConnection.g

Expanding Redundancy with the DataHub Combine all features of the DataHub to make most of your data SMS/Email alerts when fail over occurs Bridge data between domains Log to a Database Data Tunneling Data Aggregation Easy set-up
10
What is Tunneling? OPC Tunneling Moving OPC Data via simple TCP/IP port connection Eliminating DCOM and Expanding Data Transport Choices Computer #2Computer #1
11
3 Steps to Tunneling with OPC DataHub Step 1: Connect Master to OPC Server Step 2: Connect Master to Slave Step 3: Connect OPC Client to Slave
12
OPC Tunneling Why Tunnel? 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
