Industrial IoT Gateways Use Cases and Deployment Options

Let’s look at a few real-world case studies to better understand the challenges of building industrial IoT gateways.

Industrial IoT Gateway Use Cases

Factory Automation
Industrial IoT Gateways facilitate the communication between tens and thousands of IoT devices, machinery, sensors, and factory equipment, as well as communication between these devices and the cloud. They enable remote monitoring of factory assets and control of such assets.

Smart Manufacturing
The IIoT gateway enables real-time monitoring of PLCs, provides remote access for diagnostics and troubleshooting, offers data visualization and analytics, and allows for integration with higher-level manufacturing systems. It enhances the efficiency, visibility, and control of PLC operations, enabling proactive maintenance, optimization, and decision-making in manufacturing plants.

Smart Energy Consumption Monitoring
In industrial settings, IIoT Gateway can be used to regularly monitor and manage energy consumed by machines. Sensors, meters, and other IoT devices can be used to track how much energy each piece of equipment consumes. As a result, strategic actions can be taken to subdue the consumption of electricity and boost the overall efficiency of a facility by collecting energy utilization parameters.

Enterprise IIoT
An IIoT gateway for enterprise applications acts as a communication hub, connecting operational technology devices to the information technology infrastructure. It collects and transmits data from various devices, performs protocol translation, enables edge computing for faster insights, ensures data security, and facilitates integration with higher-level systems. The IIoT gateway streamlines data flow, enhances operational efficiency, and enables real-time monitoring and decision-making in enterprise environments.

IoT gateways play a vital role in changing traditional transformers into intelligent, connected assets. They enable remote monitoring, diagnostics, predictive maintenance, fault detection, and easy integration with broad grid management systems. Sensors installed in transformers are used to collect real-time data such as temperature, oil levels, vibration, and electrical parameters to enable proactive maintenance.

Connecting IoT devices securely to the cloud and gathering data from them can be daunting, but it does not have to be. With features like remote management, network mapping, security options, and more, IoT Gateways provide an easier way to connect and manage everything from data security and connectivity protocol to edge computing.
