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.

A key feature of any HMI package is the ability to not only show the current state of your control system, but to then store that information for historic purposes. But being able to easily access that historical data is key for making important decisions.

LGH File Inspector enables scalable, fast access to local daily historical data files (*.lgh files) logged by AVEVA InTouch HMI and SCADA applications without the limitations imposed by other solutions.

In this blog post, we'll cover how to seamlessly integrate LGH File Inspector with InTouch using InTouch scripting using two different methods.

Did You Know? How to "Simulate" Devices with OmniServer

6 min read

If you're familiar with OmniServer, you likely already know how OmniServer is commonly used to retrieve information from devices that use ‘non-standard’ protocols to communicate such as weight scales, barcode readers, and printers either over serial connections or Ethernet connections.

But a common challenge is configuring an OmniServer but not having a real device physically available to test against. However, with a little extra configuration and a second PC with OmniServer installed, you can create a "device" version of the same protocol to test against.

Reviving our "OmniServer Did You Know?" blog series, I will cover how a second OmniServer can be configured to act as a test device for troubleshooting your protocol when a physical device isn't available.

The Google Cloud Platform (GCP) is Google’s cloud solution that brings all of Google’s cloud computing services together. Google’s own services, such as Google Search and YouTube, run on the GCP, but end users can also use their cloud services.

Google Cloud Platform, for the Internet of Things (IoT) area, offers their “Cloud IoT Core” services, which provide the functionalities to connect large quantities of devices via an integrated MQTT broker. In this blog post, we will show the necessary steps for connecting this Cloud IoT Core to the different data interfaces supported by OPC Router.

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

10 min read

By Nicole Knox on Apr 7, 2022 2:00:00 PM

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.
