Connecting Legacy Equipment to the Industrial Internet of Things (IIoT)

Mike Godsey | May 26th, 2016

Message from Mike:While interest in the Industrial Internet of Things (IIoT) continues to build there are myriad questions surrounding the implementation of IIoT. Questions such as “What type of analytics will I use?” “How will IIoT impact my IT infrastructure and budget?” “Who is going to manage all of the data?”. These are all valid questions and concerns, but just as there are many high level issues there are just as many down at the device level that need to be addressed if not first, then at least simultaneously with the higher level concerns. In the white paper below, “How Protocol Conversion Addresses IIoT Challenges” Red Lion Controls addresses what I believe to be one of the major device level questions facing IIoT implementation.

How Protocol Conversion Addresses IIoT Challenges

Aggressive growth forecasts are helping to fuel interest in both the Internet of Things (IoT) and the Industrial Internet of Things (IIoT), but details on what is required to make either a reality are still a bit hazy. Within the industrial sector, connecting disparate devices from multiple manufacturers is a key first step to creating the IIoT and is made possible through protocol conversion. After defining protocol conversion, this white paper will explore how this fundamental IIoT building block helps organizations connect devices, monitor processes and control operations to extend equipment lifespan.

Introduction

According to Berg Insight, the number of wireless Internet of Things (IoT) devices in automation networks is currently forecast to grow at a compound annual growth rate (CAGR) of 27.2 percent to reach 43.5 million by 2020. While figures like this help make the IoT a hot topic, there seems to be a bit of mystery for some around what is needed to truly make it work. The same holds true for the Industrial Internet of Things (IIoT), also referred to as Industry 4.0 and the Connected Factory by some. After defining protocol conversion, this white paper will explore how this fundamental IIoT building block helps organizations extend equipment lifespan.

What is Protocol Conversion?

Protocol conversion is a key first step in solving the multi-vendor and legacy equipment challenge. Wikipedia describes a protocol converter as “a device used to convert a standard or proprietary protocol of one device to the protocol suitable for the other device or tools to achieve the interoperability.”

There can be many different devices on a manufacturing floor, with each one having its own protocol, so organizations can have a situation where they need to handle several different protocols in order to gather data. The ability to provide protocol conversion in a Human Machine Interface (HMI) or other automation products across a multi-vendor environment is a great way to connect, monitor and control several different devices, with different protocols, and be able to aggregate that data collection.

How to Use Protocol Conversion

Protocol conversion is essential when it comes to the IIoT because organizations often have a “mixed bag” of devices that have different ages and come from different suppliers or manufacturers. Sometimes these devices can be 5, 10 or even 20 years (or more) old. How can organizations be IIoT “ready” when many use legacy devices to operate numerous processes? Replacing equipment is not an option because of cost and integration time.

By implementing the following steps, organizations can protect and make existing investments compatible with more modern equipment:

  • Connect devices: get disparate equipment to communicate across multi-vendor environments
  • Monitor processes: collect and analyze data to develop more efficient processes and reduce downtime
  • Control operations: work with existing PLC, PC or SCADA systems to collect and process data in real time for critical control applications

Connect Devices – Speak the Same Language

Business operations can benefit from bringing new and legacy equipment together on the same network. Some of the newer equipment on the factory floor may be “Ethernet ready” while older equipment may use a serial connection and a legacy protocol specific to that vendor. By integrating different devices (and getting legacy devices talking with newer devices), organizations can get disparate equipment to communicate across multi-vendor environments.

Industrial environments are embracing newer communication infrastructures such as cellular M2M, Wi-Fi, Gigabit Ethernet, fiber and Power over Ethernet. These communication technologies help deliver and enable higher-bandwidth applications that bring more information and intelligence to manufacturing environments.

Monitor Processes – Use Data to Visualize

Protocol conversion is also important for monitoring processes – collecting and analyzing data to develop more efficient operations and reduce downtime. In particular, when protocol conversion is implemented in multi-vendor environments, customers can leverage visual management solutions to display Key Performance Indicators (KPIs) that can be used for tracking, assessing and analyzing manufacturing processes. These performance meas-urements are commonly used to evaluate success in relation to goals and objectives. While KPIs tend to vary by organization, common examples of KPIs in manufacturing include: count (good or bad), reject ratio, rate, target, Takt time, Overall Equipment Effectiveness (OEE) and downtime.

Control Operations – Increase Efficiencies

Protocol conversion can help organizations integrate PLCs, PCs and SCADA systems to collect and process data in real-time to control devices and applications that directly affect operations. Exercising control over operations could mean such things as having the ability to turn legacy serial-connected equipment on or off, or open or close valves regardless of location.

Overall Implementation Benefits

Addressing IIoT challenges through protocol conversion enables organizations to improve productivity and increase operational efficiencies through real-time device connection and data processing. With protocol conversion, organizations can get networked devices – both legacy and new – communicating to provide a holistic environment view that allows for more effective decision making. By enabling disparate devices to communicate, organizations can now connect, monitor and control operations from a single platform to:

  • Extend equipment lifespan:increase the value of legacy equipment with powerful protocol conversion
  • Improve process visibility: gain insight and drive productivity with data logging and communication capabilities
  • Push control to the edge: scale systems management with control capabilities at the device instead of the central office

Taking Action

Protocol conversion is a way to get there by getting devices to speak the same language, so to speak. For example, some of the newer equipment in a facility may be “Ethernet ready” while older equipment may use a serial connection and a legacy protocol specific to that vendor. By using automation products such as HMIs or the Data Station Plus from Red Lion Controls that offer several serial, USB and Ethernet ports in combination with support for over 300 industrial protocols, organizations can easily integrate different devices (and get legacy devices talking with newer devices) to get different equipment to communicate across multi-vendor environments. In closing, protocol conversion is a concept that organizations should start looking at now as part of the blueprint for IIoT readiness.
