Features & Benefits of the IIoT

This image represents the beauty of the IIoT. The data is unlocked and optimized so only the data required/requested goes where it is needed. Communication networks are protected from excess traffic and the operator can focus on information critical to their task at hand because unnecessary data clogging the network and distracting the operator is kept out of the system.

  • Faster transfer of information
  • Automatically receive data updates
  • Reduced costs
  • Increased amount of open communication
  • Easier system set up and management
  • Reduced network traffic due to eliminating the back and forth compared to traditional systems.
  • A system that is more responsive to change
  • Email notifications for alarms and data backups
  • Remote access/monitoring/control functionality
  • Data logging for more informed operation and decision making
  • Enhanced network security thanks to physically separate dual Ethernet ports.

Edge Gateways

An Edge Gateway unlocks valuable data created by existing operational technology, enabling your business to monetize it further with the power of information technology. In the manufacturing sphere, edge gateway devices translate existing data used by control applications into an IIoT-friendly format, sending that data to the Internet for use by IIoT applications.

For successful deployment, an edge gateway device must fulfill key requirements. It must communicate with a wide range of existing equipment and support emerging IIoT protocols such as MQTT and OPC UA. It must be efficient, reliable, and scalable. It must be easy to configure and put into service. Above all, it must be secure.

With support for over 300+ current and legacy industrial automation protocols, enabling them to communicate with a wide array of PLCs, sensors, and more, our HMIs can convert factory floor data into data into an IIoT-friendly format, which can be transmitted to a local data collection point or the cloud.

A Human Machine Interface (HMI) is a perfect edge gateway. The HMI, the operator’s window into the machine in the physical world, can easily be extended to play the same role in the virtual world. The HMI is the place where data is aggregated, filtered, and presented to the operator in an intuitive and digestible way. This same data can easily be presented to users connecting to the HMI through the IIoT.


Designed to be light weight, open, and simple, MQTT is a subscriber/publisher messaging transport protocol that is considered a great solution for applications where a small code footprint is required and/or network bandwidth is scarce. It is particularly suitable for continuous monitoring of sensory data such as temperature, pressure, water level, energy monitoring, etc.


Open Platform Communications (OPC) Unified Architecture (UA) is a communication protocol supported by many SCADA, MES, and ERP software providers. OPC UA uses a Client/Server architecture. This protocol has built-in security with signed and encrypted data transfer using state-of-the-art encryption algorithms. Data is organized into objects, making it easy to access and quickly understand what the data represents, and how to use it.

  • Select Maple Systems products come with OPC UA Server functionality built-in, or in most cases, it can be added to non-supported HMIs with a license purchase.
  • All of our HMIs can act as an OPC UA Client.

SQL Database

Select Maple Systems HMIs can send machine metrics and production data or recipes to an SQL database system directly without any middleware system. That data can then be managed on a larger scale using batch database operations. They also support a built-in database query viewer which enables production machines to retrieve data from your central SQL database.

EBPro Configuration Software

Creating a powerful edge gateway at a great price has never been easier.

IIoT protocols used to convert factory floor data into an IIoT-friendly format where it can be used company-wide, regardless of the user’s location.

Pick and place objects, pictures, and shapes; create trend display, graphs, XY plots, and pie charts; add passwords and security levels; assign communication (PLC) drivers easily, and more.

EasyAccess 2.0

EasyAccess 2.0 is a “cloud service” that allows you to instantly and securely communicate with your Maple Systems HMI from anywhere in the world. Accessibility from outside the plant provides the opportunity to troubleshoot or add new features to the HMI/PLC program by qualified personnel without ever leaving company headquarters.

An administrator grants access to specific HMIs and groups, and traffic is encrypted and secured with VPN. Remote troubleshooting saves money by reducing downtime, travel, and personnel costs. EasyAccess 2.0 integrates perfectly with a wide variety of displays including desktop PCs, laptops, tablets, and smart phones.

Case Study: A Global Network

Company A feels the squeeze of market pressures. They need to stand apart from competition and increase profits. With global customers utilizing multiple machines per site, Company A wants to offer customers remote access/monitoring, remote functionality including email alarms, safely enable offsite troubleshooting and configuration, and reduce travel expenses and costly downtime. Company A realizes the IIoT is a great opportunity to differentiate their products.

EasyAccess 2.0 is chosen for secure remote access and its remote troubleshooting capabilities. The MQTT protocol is chosen for its extensive use and documentation with Facebook messenger, established cloud compatibility, and lightweight efficient nature for transporting large amounts of data across wide networks. MQTT also allows Company A to seamlessly expand their existing Amazon Web Services without hogging all available network bandwidth at each manufacturing site.

The company’s engineering departments utilize many different PLC brands, all with different protocols. Machines are not able to easily communicate with each other. Thankfully, Maple Systems HMIs have excellent legacy protocol support, enabling data retrieval and conversion from a wide range of existing protocols, serving as a gateway to the IIoT.

Company A finds their solution in cMT3092X 9.7″ dual-Ethernet HMI, which serves as both an HMI and edge gateway. The cMT3092X supports the MQTT protocol and over 300 control protocols, enabling the linking of existing control networks with the IIoT. Dual-Ethernet ports offer functionality and security, separating operational technology networks inside the machine from external information technology networks that can be used for an EasyAccess 2.0 connection. This secure connection safely allows for advanced remote functionality such as email alarms, remote access, remote monitoring, and remote programming. As an OEM, dual-Ethernet HMIs allow Company A to maintain an isolated network dedicated to their machinery, yet still offer access to the Internet through their customer’s ISP. The publish/subscribe architecture of the MQTT network and EasyAccess 2.0 VPN connection means they won’t have to bug their customer’s IT departments.

The cMT unit set up is simple and allows them to quickly and easily create control interface projects and take advantage of powerful IIoT features. Because their systems are widely distributed, Company A hosts their MQTT broker offsite with Amazon AWS. Their new data stream is connected to a web application that customers can log into for real-time machine monitoring. EasyAccess 2.0 remote functionality built into the HMI allows Company A to update projects (including offsite MQTT setup) to meet changing customer demands without spending time and money onsite. The company is able to respond faster to software and data demands across their deployed equipment without ever leaving company headquarters. Company A utilizes predictive maintenance instead of preventative maintenance, enabling them to cut costs, improve troubleshooting, and decrease downtime. New machines added to their deployed network send smart data back to the central database for analysis. Sales overall increase because users feel the benefits of more data, accessible to more people.

For future machine builds, Company A will be able to proactively design units by analyzing data from their deployed equipment. Real-time data from deployed cMT3092X units will show how customers actually use their machines as well as highlight popular features used and those to be eliminated. This helps tailor future marketing efforts. Future machines will evolve according to specific data collected on how each feature is used, where the machine shines, and where it struggles.

Case Study: A Single Factory

Company B is a single-facility food processing company. Like many in the manufacturing industry their biggest obstacles for IIoT adoption are budget and interoperability. They have an existing SCADA package installation with OPC UA capabilities and a MySQL database.

Company B’s factory has both Ethernet and serial control networks unable to share data due to incompatible protocols. The company wishes to centralize data without incurring additional costs for new server equipment and remote hosting. Key requirements for IIoT hardware include support for the OPC UA protocol, legacy protocol support, and secure remote functionality. One of our headless cMT-SVR units paired with an OPC UA license is a perfect fit for Company B’s needs since they do not require new displays. This unit is affordable with a small form factor which fits into existing panels.

Company B creates both a project with the necessary communications drivers and an OPC UA Server inside their new cMT-SVR. They define OPC UA tags to bring data from the plant floor into the informational environment, routing that information to dashboards and the SCADA software already in use by management. They also sync data logs to their centralized MySQL server for further analytics. Instead of relying on old data trickling into the system by manual entry, analytic software now offers a live data stream from operating machinery.

Remote access capabilities of the cMT-SVR unit dramatically change how Company B interacts with their system. The cMT-SVR unit connects to a laptop/PC or Android/iPad smart device with the free cMT Viewer application, freeing floor managers up to access/monitor machines from the palm of their hand. The email alarm feature alerts staff immediately when something runs amiss, delivering email alerts regardless of location. Dual-Ethernet ports plus serial communication offers a safe connection to office networks exposed to the Internet.

System awareness improves due to centralizing data from all facility machinery. Maintenance costs reduce thanks to linking machine wear data to usage data, improving machine use and extending machine life. By identifying data patterns that indicate likely failures, equipment life is extended, enabling machines to run to full life without risking costly shutdowns. By linking existing control hardware into a single database for access and analysis, Company B increases both the value and profit from data they were already collecting. Streamlined operation, predictive maintenance, and focused growth are achieved. For future machine additions, management will utilize detailed statistics on their highest profit machines and process bottlenecks. The versatile cMT-SVR unit paired with a OPC UA license can integrate with any vendor’s machine and resource management system, meaning Company B will not be limited to using a single vendor. This will allow future growth targeted toward areas where the greatest impact will be achieved at the lowest cost.
