Tech Support Corner: How to Script Wireshark Capture

5 min read

By Rodrigo Restrepo on May 19, 2022 2:00:00 PM


As you may be aware, Wireshark is an incredibly useful freeware tool for capturing network traffic on a computer. Our support engineers find it to be invaluable for troubleshooting Ethernet communications issues, as it provides visibility into more than just the protocol data packets, including handshaking calls and responses.

Wireshark also provides options for specifying capture filters (for defining a smaller subset of data to be captured that you're interested in) or you can capture all traffic and apply a display filter to narrow down the traffic that is visible.

Continuing our Tech Support Corner blog series, this blog post covers how to go even further using Wireshark by defining scripted custom Wireshark captures for specific use cases, which is helpful for capturing infrequent issues without wasting a lot of unnecessary hard drive space.

Tech Support Corner: Running / Maintaining Cogent DataHub as a Service

10 min read

Great job! You managed to configure Cogent DataHub® to fit your needs, and now you are ready to run it in a production environment, but you are left with one question – “How in the world do I run DataHub as a service?”.

Running applications as Windows services has multiple benefits but, perhaps, the most beneficial reason to run an application as a service is the ability to let the application/process run in the background without the need for a user to be logged on the operating system. For that reason, this might be why you are looking at how to run it as a service, whether you are tunneling, logging, aggregating, historizing data, and/or using Datahub as a Gateway.

Continuing our Tech Support Corner blog series, if you find yourself in this situation like other users over years, do not worry. This post will walk you through the process of running DataHub as a service as well as how to access its properties from a local and/or remote machine.

By Win Worrall on Mar 10, 2022 2:00:00 PM


Cogent DataHub® (from our developer partner/publisher Skkynet) provides a wide selection of connectivity options to OPC DA, OPC UA, OPC A&E, Databases, Excel, ODBC, DDE, Linux, Modbus.  As you may have already learned recently, DataHub Version 10 now includes support for integration with a wide range of common external historians. This expands your options for which data sources are compatible for historization in your chosen historian solution beyond the historian's native interfaces.

In this blog post, we'll detail how to get started integrating your data sources accessible by DataHub with AVEVA™ Insight, by writing data to your AVEVA Insight instance while also making that same historical data available for trending, visualization and reporting for both DataHub and external historical clients supporting OPC UA Historical Access (HA).

Tech Support Corner: Troubleshooting AVEVA SuiteLink Connections

10 min read

By Connor Mason on Feb 24, 2022 2:00:00 PM


Software Toolbox has a long-standing history of offering supplemental solutions that fit right in with AVEVA™ (formerly Wonderware®) projects. Many of you will be familiar with our TOP Server for AVEVA™ that offers a variety of device connectivity options, and a variety of client interface options like SuiteLink, OPC DA, and OPC UA.

SuiteLink is a communications protocol that runs over TCP/IP at the application layer, created by Wonderware to replace/succeed FastDDE, in the mid-1990's. Unlike OPC DA, SuiteLink doesn’t rely on COM or DCOM technology, making SuiteLink a common choice for remote connectivity to Software Toolbox solutions.

Continuing our Tech Support Corner blog series, this post shares best practices and procedures to follow when attempting to troubleshoot a SuiteLink connection, specifically when it comes to using SuiteLink clients with TOP Server. While this post specifically uses TOP Server as the SuiteLink server, the same techniques and concepts also apply to OmniServer, which also has a SuiteLink client Interface and is commonly used with AVEVA solutions.

By Jessica Dillon on Feb 17, 2022 2:00:00 PM


If you are reading this post, chances are that you are somewhat familiar with TOP Server as well as how to configure it to communicate with various devices. Perhaps, you are also familiar with how to configure different settings, OPC UA endpoint settings, Licensing, Stop and Start the Service, and, if you are a developer, you might be familiar with the development resources that TOP Server offers such as the Remote Config REST API and the OPC.NET interface.

However, during our daily interaction with end-users, we often find that there is a misconception of what the TOP Server application is composed of and how each component contributes to delivering the product that you interact with daily.

Continuing our Tech Support Corner blog series, this short post will discuss the various components of TOP Server and clarify how each component contributes to the macro process that allows the application to deliver communication between your process devices and your various IT/OT systems.
