In a recent blog post about MongoDB, we discussed how non-relational database differ from relational databases like SQL and MySQL. The fact of the matter is, relational databases are widely used and still just as popular in the industrial automation space as ever. A popular alternative to SQL and MySQL is MariaDB which is an open source relational database.

This blog post (based on the article "What is MariaDB? A comparison with MySQL" by our partner company, inray Industriesoftware GmbH) discusses what MariaDB is, comparing it to MySQL so you can determine if MariaDB is a better database option for your company.

MongoDB and How a NoSQL Database is Different

I think it's safe to say that when we're discussing databases in the context of industrial process control, SQL Server is where most of our brains tend to jump. The proliferation of SQL (and other traditional relational databases) across most, if not all, industries for process control applications cannot be denied. But SQL (and others) do certainly have some limitations.

This blog post (based on an article by partner company, inray Industriesoftware GmbH) discusses how MongoDB, a non-relational database (i.e. NoSQL database) are fundamentally different from the SQL Servers of the world and how MongoDB can be a good alternative to relational databases for some applications.

How to Log Data From Your S7-1500 via OPC UA using OPC Data Logger

4 min read

By Tyler Lindsey on Aug 29, 2019 2:00:00 PM

With the relatively recent availability of OPC UA server capabilities in Siemens S7-1500 PLCs, access to live production data is now open to third-party applications. As a result, those applications can now communicate with hardware that was formerly locked behind proprietary communication drivers.

The OPC Data Logger's OPC UA client interface allows users to quickly and easily connect to S7-1500 PLC’s and log data to their preferred data storage option without the need for intermediate applications. This blog post covers the high-level steps involved with logging data from an S7-1500 controller and you can then download the free hands-on guide with detailed steps.

OmniServer Wedges are included with OmniServer Professional Edition.  Wedges are built-in components providing additional useful capabilities that expand the functionality of OmniServer beyond its core connectivity and data parsing abilities for non-standard devices.

The OmniServer Database Wedge allows you to log your device data to any ODBC-compliant database, including SQL, with a highly configurable format and flexible conditions.  And this ability is built into OmniServer, eliminating the need for separate external components or applications.

In this video blog, I'll show you how to get started using the OmniServer Database Wedge to easily log process data based on specified conditions, making it possible to monitor trends in your process and easily report on your process data or troubleshoot any issues that are discovered.

Yes, You Can Integrate Business & Other Databases with Control Systems

5 min read

By Win Worrall on Nov 16, 2017 2:00:00 PM

It is common for companies to use databases for long-term storage of their critical information.  In our experience, we also see machine setup information, short term operational data and much more besides traditional historical data put into shop floor databases in the operations technology or “OT” world.

Over on the business side or the “IT” world, everything somehow ends up in a database: Production plans, forecasts, orders, it’s all there.  Increasing business demands and IT/OT convergence are driving more real-time integration between these databases and control systems.

This blog discusses some of the key reasons users like yourself need this information and then shows how the DataHub can help move this data from a database to your control systems via OPC DA, OPC UA, Modbus and other interfaces or protocols that are common in the automation layer.

Can Your OPC Tunnel Unlock All of Your Data Sources?

2 min read

By Win Worrall on Aug 23, 2016 12:39:14 PM

The word tunneling, when it comes to industrial automation and data, typically goes together with OPC.  OPC tunneling is generally the most common form of tunneling, but what if your data sources aren't OPC?

What if you have more than just OPC clients and servers in your architecture and those non-OPC data sources have vital information that needs to be collected and shared with your other systems?

This blog post will discuss why it's  important for a tunneler solution to support more than just OPC-capable data sources in a diverse control system.
