Demystifying Modbus Function Codes

Posted by Kevin Rutherford on Dec 13, 2018 2:00:00 PM

With the wide range of devices that use Modbus for their communication protocol, you'll find many different interpretations, terminology and labels with respect to how to access different types of data in those devices.  Sometimes a device manual might only refer to the supported Modbus function codes and the range of offsets available for those function codes.

In this blog post, I will step through the specifics of Modbus function codes and how they pertain to addressing, and how they affect what addresses to use in TOP Server for Wonderware applications.

Demystifying Modbus Register Addressing with TOP Server for Wonderware

Posted by Kevin Rutherford on Oct 11, 2018 2:00:00 PM

I'm sure you've all at least had some interaction with Modbus, working in the automation industry.  It's one of the most widely used protocols (if not the most widely used) in the world.  Which is both its blessing and its curse, to some extent.

Given how long Modbus has been around and in use as an "open" protocol (starting in 1979), there have been many different interpretations of Modbus throughout the years.  And with those different Modbus interpretations, much confusion about the different terminology for accessing data.

In this blog post, I will step through the basics of Modbus addressing including how offsets come into play, and how they affect what addresses to use in TOP Server for Wonderware applications.

Comprehensive EFM Data Collection and Export for PGAS, Flow-Cal, CSV & Database

Posted by Kevin Rutherford on Sep 27, 2018 2:00:00 PM

If you're reading this post, you're more than likely working in the oil and gas industry, and you probably have flow computers and devices from different vendors storing historical EFM (Electronic Flow Measurement) data.  And, if your company is anything like the other companies in that industry, you use that EFM data for analysis, custody transfer and production optimization using one of the common EFM flow measurement analysis packages such as Flow-Cal, Quorum PGAS or even CSV or SQL.

In this blog post, I'll cover the video how-to resources available to help you get started using our EFM Suite for TOP Server to poll and export collected EFM data from various flow computers for Wonderware applications.

Namibia Brewing – Enterprise Data Integration Update & Award

Posted by John Weber on Aug 16, 2018 2:00:00 PM

Earlier this year, we shared the story of how Namibia Breweries Ltd is using off-the-shelf open OPC software in their operations management system.  In that story, we shared how we had learned making beer in one of the world’s driest places takes some unique approaches to power sourcing, water management, and really all resources.

We visited with Namibia Brewing again recently when they attended the X-Change 2018 conference in the beautiful Central Drakensberg region of South Africa.   I had the chance to sit down with Annemarie Kruger, Renaldo Du Pisani, and Andre Engelbrecht and, in this blog post, you'll learn about how they have continued to evolve their system since I visited their site in 2017.
