Cogent DataHub is primarily known for its extensive connectivity to OPC DA, OPC UA, OPC A&E, Databases, Historians, Excel, ODBC, DDE, Linux, Modbus and more. However, it is worth noting that this platform offers more than just connectivity. In this blog post, we'll cover the capabilities of DataHub’s Alarm & Notification Plug-In, which supports the configuration of custom alarms, events, and notifications. You can enhance your A&E Client applications by adding this feature to any DataHub License Pack, and generate alarms based on any data integrated into the DataHub, or simply send email/SMS alerts.

It's pretty common these days for companies to use Microsoft Teams™ for internal communications within and between departments and maybe even between IT and OT segments in an organization. This has become more and more important with increasing remote office scenarios, enabling vital collaboration between key members of an organization.

But what if you could also have real-time updates from your process and other systems in the same fashion? Rather than a colleague messaging you about an urgent matter, what if your actual processes and even business systems could message you via Teams with actionable information (possibly a line is down, or a tank level is approaching maximum level)?

In this blog post, we'll cover the steps necessary to use OPC Router to integrate your variety of systems with Teams so that you can have real-time updates and make important decisions about your business more quickly.

Cogent DataHub enables a wide range of connectivity interfaces for different data sources such as OPC UA, OPC DA, ODBC, DDE and so much more.  This makes DataHub a flexible gateway commonly used for data integration by external software such as HMI, SCADA, MES, historians and other client applications.

In this video blog, I'll show you how to use DataHub V10's support for OPC UA Alarms & Conditions to enable OPC Classic Alarms & Events servers to work with newer OPC UA clients supporting Alarms & Conditions.

If you've heard of the Cogent DataHub, you may be aware that it supports email and/or SMS notifications of defined conditional events based on a variety of data from it's various supported interfaces (MQTT, OPC UA, OPC DA, DDE, ODBC and more).  Having the right people receive alerts (such as when a tank has reached a critical level or a critical piece of machinery is offline) in a timely fashion can be the difference between simple downtime and a major liability.

This blog post will discuss how to use variable distribution lists in conjunction with the Cogent DataHub's Email/SMS capabilities to ensure the right decision makers will always receive important notifications as quickly as possible.

Knowledge is power and knowing the current state of your underlying server hardware for your process can be very powerful indeed.  Keeping a pulse on information like CPU usage, available memory, memory consumption by a process and whether or not critical process are still running can be the difference between hours of downtime with thousands of dollars in lost production and being able to proactively avoid any downtime.

The following short video blog demonstrates step-by-step how easy it is to use the Cogent DataHub to monitor vital system statistics on your servers that can be shared in real-time via supported client interfaces such as OPC DA and OPC UA or even send email/SMS notifications.

Timely notifications about abnormal conditions in your process are vital to minimizing downtime and the costs associated with it.  Automating the process based on the condition of specific process variables gets you the information you need for making decisions as quickly as possible.

The following short video blog demonstrates step-by-step how easy it is to use the Cogent DataHub to establish a connection to an OPC data source and then define various flexible conditions for triggering email and/or SMS text notifications based on values collected from that OPC server.

The heart of any control system is the computers and servers that run your automation software.  For example, when PLCs talk to AC drives over Ethernet, the drives will shut down if they lose communications for more than a second, sometimes even milliseconds.  Drives shutdown = Line shutdown = Plant shutdown.  What IT calls a blip for plant operations can mean downtime, scrapped product and even your company’s reputation due to missed delivery deadlines.

Traditionally, server maintenance and upkeep is the role of IT.  However, when these systems go down, it affects operations (OT) with different pains than IT sees on the business side.  IT has systems to monitor their own assets, on the standards they need for the business, but they need the OT side to expand monitoring of their own systems and self-reliance in order for OT to meet operational needs, while bringing in IT as a resource.

This blog post will discuss how to get information about health of servers and PCs that runs the automation software OT users need without having to rely solely on IT.

In the automation and control world you need to know about problems immediately.  If problems are not recognized early enough, they can cause unexpected downtime, damage to machinery or environmental impacts.  In other words, these problems can cost you a lot of money.

Fortunately, these days most of us have 24/7 access to email or texting through their laptops and smart phones which has made receiving alarms in a timely fashion much easier than in the past.

In this third post of our “I Can Do That?” blog series, we’ll cover how to get alerts to problems ASAP and also share some specific use cases for email/SMS notifications using Cogent DataHub.
