The use of certificates in cryptographic applications and online communication protocols is nothing new and can practically be traced all the way back to the 1970's when the "framework" for public key encryption (more on this in a future blog) came into being. With the (now-not-so-recent) Industry 4.0 movement coming out of Europe, and the design and operation changes brought about by the IIoT phenomenon, we are seeing more and more systems – that have traditionally been air-gapped and kept offline – being brought online to take advantage of the digital revolution in which we find ourselves.

Despite how you feel about this (r)evolution there are several exciting changes that are being brought about, including the one I want to discuss is the increased adoption of OPC Unified Architecture (OPC UA) in automation systems.

In this first post in our ongoing Exploring OPC UA blog series, we will look at what OPC UA Certificates are and what they provide and subsequent posts will further explore how they are used in OPC UA, how they fit into the security ‘stack’ of OPC UA and will then look at how OPC UA Certificates are utilized and managed in several Software Toolbox applications. First thing’s first however; what are OPC UA Certificates and what are they used for?

If you're interested in LGH history data and are reading this, you likely have your own use case for working with InTouch LGH history files.  Given that LGH files are a classic method for InTouch users to log historical process data, the use cases for LGH history data are similar to any other use cases for historical data.  Trending and predictive analytics can be key methods that utilize historical data for identifying process issues and resolving them in an efficient and cost-effective manner.

This blog post covers a specific use case involving an engineering research student working on a condition and performance monitoring system for subsea hydraulic systems targeted at identifying the health of the system and supporting predictive maintenance.

Whether your role is IT or OT, there tends to be an almost universal dislike of having to work with printers. It is likely, for this exact reason, that when tasked with integrating a printer (be it a laser jet printer for labelling packaging, or a label printer to track your products) many users are simply forgoing the integration completely.  That might mean opting for limited integration with a PLC on the line or simply choosing to not integrate at all while continuing to make any configuration changes manually.

In this blog post, continuing our OmniServer Did You Know series, we’ll discuss several methods that users have implemented over the years when needing to use printers in a process and how OmniServer provides an off-the-shelf, easy-to-use alternative for direct integration of most printers with your process control systems.

The LGH File Inspector is used for many different application types as a way for users to gain added value from Wonderware InTouch local history or LGH files.  With our global user base, it’s common to have different time zone and time format requirements.

In this blog post, we’ll discuss some key enhancements in the LGH File Inspector Version 1.4.2 release that increase flexibility for users with unique time zone and time format needs.

What is the most important feature for any data logger to have? At the end of the day, we are trusting a data logger to take our data and store it.  Now whether that is for reporting, optimization, legal reasons, or simply to retain process data over some period of time in case it might be needed later, we expect the data to be logged without any losses.

This is particularly true in the industrial automation space, where the amount of data that is being logged is growing almost as exponentially as the speed at which the data is needed in order to have a business impact. As such, the prospect of losing data can very quickly result in lost jobs, thousands of dollars in lost production, and legal or financial penalties in case of an audit.

So how much do you trust your data logger to really be logging 100% of the data that it should be? In this blog post, I will address these concerns and highlight the ways OPC UA provides capabilities that software applications can leverage to provide peace of mind.

Does your data logging software force you to define the location where you're logging your data ahead of time?  Wouldn’t it be nice if your logging software could evaluate your data and make a decision on where the data should be logged?

In this first of two posts in a series on dynamic SQL logging, I'll show you how the OPC Data Logger can easily be configured to switch between SQL Tables at runtime, reducing any post-log sorting you have to do in SQL and saving you time and effort in the process.

Do you need to log specific process data to a database or text file based on some predefined variable or condition? We typically refer to this concept as "conditional" or "condition-based" logging.  It sounds simple enough but without a plan, it can be a tricky task to implement.

In this post, I'll introduce you to the considerations involved with conditional data logging and cover how OPC Data Logger can easily be set up to log data based on a variety of conditions without a lot of headaches.

Does your non-standard instrument connected to your COM1 serial port refuse to communicate without being told how? Do you need to tell the instrument what bank of memory to use before you can extract any data? Does the instrument require setup parameters before it will work? Do you not want to script this in your client application, and don’t want to expect a user to manually initialize a device before doing anything else?

With OmniServer, there is an auto-activated message flag that's exactly the feature you have been looking for when communicating with your non-standard devices and instrumentation.  This fifth post in our "OmniServer Did You Know?" blog series focuses on how to use OmniServer's setting for auto-activating a command protocol message to initialize communications with your device automatically on startup.
