For many industries, where having access to process data is critical, it's common to implement redundancy on many levels to ensure there is no disruption to data collection. While there are different levels of redundancy, the one we see users most interested in is with OPC data source redundancy.
The following short video blog demonstrates step-by-step just how easy it is to configure the Cogent DataHub to handle redundant failover between OPC UA data sources, OPC DA data sources and more.
In this video you will learn how to setup the Cogent DataHub for redundant hot-standby data sources. Specifically, you'll see how to setup redundancy for OPC UA data source and OPC DA data sources, though DataHub supports redundancy for any data sources that it supports. For an in-depth discussion of OPC Redundancy, check out this other blog post!
Just to summarize, in this video, you've seen:
- A review of what you'll need for OPC UA or OPC DA data sources when configuring a redundant connection.
- How to add a redundant connection for OPC DA data sources including:
- Defining primary and secondary OPC DA data sources
- Defining the condition for failover between OPC DA data sources
- Defining tags for status and control of the redundant DA connection
- How to add a redundant connection for OPC UA data sources including:
- Defining primary and secondary OPC UA data sources
- Defining the condition for failover between OPC UA data sources
- Defining tags for status and control of the redundant UA connection
- How to determine which DataHub data domain your client applications should access to take advantage of the configured redundancy.
Are you ready to beef up your process data collection by adding redundancy?
