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

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
What is Tunneling? OPC Tunneling
Moving OPC Data via simple TCP/IP port connection Eliminating DCOM and Expanding Data Transport
Choices
Computer #2Computer #1
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
OPC TunnelingWhy 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
Live Demonstration
Hot Redundancy Primary: Tunnel to Remote OPC Server Secondary: Local OPC Server
Cold Redundancy Primary: Local TOP Server v5 Secondary: Local TOP Server v4
What Tools are Needed?
For all usage scenarios No tag count limits No limits on # of clients, # of servers used with a
single DataHub
