Software Toolbox Technical Blog

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.

Do you find yourself in need of troubleshooting a TCP connection, but your IT department has everything locked down, so you're unable to install third-party Troubleshooting tools without permission? An often overlooked but effective tool for troubleshooting TCP socket connections is PowerShell.

Continuing our Tech Support Corner blog series, this blog post covers how to use PowerShell to effectively determine what issues you may be having with a problematic TCP Ethernet connection.

2021 furthered the transformations of 2020 as industry worldwide continued to adapt to succeed in the face of new challenges such as supply chain, a growing labor shortage, and exploding customer demand.  

This post is our 5th annual sharing of references to learning resources and new technology releases that users have told us were the most helpful to them over the course of the last year.

Continuing our Exploring OPC UA blog series, we're still going into the specifics of OPC UA security configuration in key Software Toolbox solutions that are OPC UA capable.

In this ninth post of the series, we will focus on OPC Router, focusing on stepping through what the settings are in OPC Router and how to get connected both for your OPC UA clients and servers.

If you've been following our ongoing Exploring OPC UA blog series, we've been covering key Software Toolbox solutions and the specifics of configuring OPC UA security and connectivity.

In this eighth post of the series, we will focus on the OPC Data Client development toolkit, with the primary topic being how to exchange security certificates and establish a trust relationship between your custom OPC UA client and an OPC UA server.

If you've been following our ongoing Exploring OPC UA blog series, we've been covering key Software Toolbox solutions and the specifics of configuring OPC UA security and connectivity.

In this seventh post of the series, we will focus on OPC Data Logger, specifically stepping through settings related to security, endpoints and certificate management and connecting OPC Data Logger to OPC UA servers for logging data.

As you may have seen in our recent posts in our ongoing Exploring OPC UA blog series, we've been going into the specifics of OPC UA security configuration in key Software Toolbox solutions that are OPC UA capable.

In this sixth post of the series, we will focus on Cogent DataHub, focusing on stepping through what the settings are in DataHub and how to get connected both for your OPC UA clients and servers.

In our ongoing Exploring OPC UA blog series, we have shifted the focus from general concepts about how OPC UA certificates and security work to looking at practical usage of OPC UA in specific Software Toolbox solutions. Last time, we focused on configuring TOP Server for OPC UA connectivity.

In this fifth post of the series, we will focus on OmniServer, our solution for getting data from non-standard devices into OPC UA and other client applications. We'll step through what the settings are in OmniServer and how to get your OPC UA client applications connected.
