JSON (JavaScript Object Notation) is a file format that has become fairly common in the industrial automation industry for storing data or information (including such things as configuration files). But also as one of the most common data formats used by RESTful APIs and web services, which are commonly used for providing a range of useful information including energy prices and weather data.

Sometimes, of course, depending on the application, some or all components of JSON packet might be variable or dynamic in nature, which can make it difficult for off-the-shelf industrial software solutions to properly parse the information from those packets.

In this post, I will cover step-by-step how to leverage the scripting capabilities of the OPC Router to access and parse JSON packets either from a JSON file saved to a specific file directory or from a RESTful web service after which that data can be used with any of the other connectors that OPC Router supports. For this example, we log the data to a SQL database.

Firstly, Happy Belated Earth Day to all that celebrated on Saturday!

Currently, renewable energy generates around 20% of all electricity in the US. This percentage increases daily - you may have seen more solar panels popping up around your neighborhood! This allows us greater potential to modernize the grid through renewable energy within our communities.  As the potential for more energy generation increases, the need for more jobs within this sector increases as well.  In fact, with the Inflation Reduction Act of 2022 (IRA), the more than $50 billion in clean manufacturing investments in the law will create an estimated 900,000 jobs over the next decade.  These strong investments will initiate a manufacturing revitalization and help to move clean manufacturing to center stage within the US.

In this fourth and final installment of our Environmental Sustainability blog series, we are going to take a look at commonly used software solutions that our clients in the Renewable Energy sector have implemented to assist with sustainable energy production.

When people think of environmental sustainability, in general, they often do not think of the oil and gas industry. But the fact of the matter is that oil, natural gas and other hydrocarbons are a large part of our global energy supply and chemical production. There are many environmentally-focused regulations that these industries must meet. Even with these regulations, the industry has begun to exceed these expectations through technology such as carbon capture as a method of reducing one’s ecological footprint.

In this third installment of our Environmental Sustainability blog series, we are discussing oil & gas industry regulatory requirements and how industrial automation software solutions empower organizations in the industry with monitoring of critical data so they can act on potential issues before they become problems, and support their reporting to meet such requirements and also with monitoring such that those requirements can be more easily achieved.

Environmental sustainability is built on the principle that everything humans need for both survival and our well-being triggers a reaction in the environment. The pillars of sustainability are based upon the interdependent relationships of the environment, the economy, and our society. Because many of the goods and services that are required for human survival are either traded for or purchased monetarily, this inherently creates an impact on the environment. So, what is the economic impact of environmental sustainability?

In this second installment of our Environmental Sustainability blog series, we are exploring just that – how investing in the sustainability of your product line can have positive impacts on the environment.

Here at Software Toolbox, we strive to be the “One Responsible Partner” for our clients - a motto we see as soon as we enter the door every morning. That extends beyond just our amazing sales and support teams. It also means being the One Responsible Partner for our Earth.

With Earth Day coming up, our team has decided to take this month to focus on the different ways our products help users achieve their own environmental sustainability goals and the conservation of natural resources in general. In this first blog post, we will take a look at how OmniServer helped a food and beverage user improve efficiency and reduce waste in a “sweet” way.

As someone who has worked with non-standard device connectivity using OmniServer for almost 18 years, I've encounter most of the subtle nuances of certain protocols that a user might need to implement and how to do so in OmniServer. One such nuance (which is true even with "standard" protocols such as Modbus) is that it's not uncommon for device vendors to implement their communication protocols with variable or parameter values that use a unique byte order compared to ordering by the first byte received to the last byte received (also referred to Most Significant Byte to Least Significant Byte, Big Endian or Motorola Byte Order).

You may not be aware that OmniServer has several flexible ways to manipulate the ordering of bytes parsed into Items to be shared with client applications to ensure that the correct and expected value is always displayed in your HMI, SCADA, historian, MES or other client applications.

Returning and expanding our "Did You Know" OmniServer blog post series, I'll cover what byte ordering settings are available in OmniServer, when you might need to use them and how.

It's common for members of the Software Toolbox Technical Team to encounter instances where users need to configure thousands of static tags for the devices in their TOP Server projects. We have even supported implementations with over a million tags.

In such situations, it would be inefficient to manually add each individual tag to TOP Server. There are several better alternatives for adding large quantities of static tags to a TOP Server project: Automation Tag Generation (ATG), Bulk Tag Creation, and/or CSV Import/Export.

Continuing our Tech Support Corner blog series, this post covers what methods you have available to mass create large quantities of static TOP Server tags and how to use them for greater efficiency.

The DNP3 protocol is commonly used in water/wastewater and other utilities related industries. It's common for RTUs used in these industries to support both DNP3 and Modbus (and possibly other communications protocols). DNP3 has many features compared to Modbus (and other more traditional protocols) that make it desirable for such remote telemetry applications including buffered event history and unsolicited (or Report-By-Exception).

But if you're new to working with DNP3 (it's common for users in such industries to be quite familiar with Modbus but not so familiar with the quirks of DNP3), it's important to understand how differently it behaves with respect to polling frequency, polling composition and considerations when configuring the DNP3 outstation/device itself.

Continuing our Tech Support Corner blog series, this post discusses what drives the polling behavior for DNP3 drivers in TOP Server and how the configuration on the device itself can impact what data is returned when a poll is issued.
