Industrial IoT Gateways and PLCs: Where OT Meets IIoT
PLCs (programmable logic controllers), which serve as the brain of factory floor automation systems and offer dependable and adaptable control methods for industrial control operations, have been at the center of these systems for the past few decades. However, new Industrial Internet of Things (IIoT) technologies are offering more sophisticated functionalities and effective solutions as a result of the rapid growth of IIoT technologies.
Industrial IoT gatewayï¾ is a device based on Internet of Things technology, which can connect multiple sensors, instruments, controllers and other devices to realize real-time monitoring and management of various parameters in the industrial environment. More significantly, the industrial Internet of Things gateway may link OT and IIoT, facilitate information flow, and encourage equipment collaboration, all of which support the advancement of industrial automation.
This article will explore the synergy of industrial IoT gateways and PLCs in automated production, and and how they might work together to increase production efficiency, lower costs, and improve product quality.
What is PLC?
PLC, short for Programmable Logic Controller, is a device specially used for industrial automation control. In order to satisfy the demands of industrial production, it uses computer control technology and programming to accomplish real-time control, measurement, and execution duties. PLCs are essential for controlling complex industrial applications' production processes and enhancing output quality and efficiency.
Although PLCs can take on a variety of shapes and forms, their fundamental function—to fulfill the automatic control of industrial production—remains the same. PLC is used extensively throughout a range of industries, including manufacturing, electric power, transportation, mining, etc. It has grown to be an essential component of industrial automation.
PLC and the IIoT
PLC is a well-known type of industrial control system, with data contact usually takes place within the local area network, and system communication typically takes place in a workshop or factory. However, a greater variety of data exchange and remote management can be accomplished by integrating the PLC control system into the Industrial Internet of Things, further advancing the industrial automation process.
For instance, real-time production line running status can be obtained through remote PLC monitoring through the Internet. This allows for the early detection and resolution of issues, increasing the effectiveness and caliber of production. Additionally, the production process can be optimized and maintained in advance through data analysis and wise decision-making, which lowers production costs and resource usage even more.
PLC and an IIoT gateway
PLCs and IoT gateways both have significant contributions to make to industrial automation, but they operate in distinct ways.
PLC
PLCs are devices with some computer-like properties that are specifically made to control industrial equipment. They are capable of doing tasks like counting, timing, arithmetic computations, and sequence control. In order to achieve accurate control of the industrial machine, it modulates the output signal using the input signal.
Industrial IoT gateway
What is an industrial gateway?ï¾ An industrial IoT gateway, on the other hand, is a kind of IoT device that connects PLCs, sensors, instruments, industrial equipment, and other intelligent hardware with features including device networking, data collecting, and edge computing. It can simultaneously transfer the gathered data to local or cloud storage programs. In order to implement device interconnection, the IoT gateway can also be utilized as a connection point between the cloud platform and PLC controllers, sensors, or other industrial equipment.
The Convergence
In order to realize PLC data on the cloud, Dusun IoT's DSGW-081 Modbus RS485 CAN Bus I/O  converter (WiFi/LTE 4G/Ethernet) has rich industrial control protocols and a variety of data interfaces embedded within it. This makes it compatible with more than 95% of common PLC devices currently available (Siemens, Mitsubishi, Omron, Schneider, Delta, AB, Beckhoff, Xinjie, Inovance, Panasonic, etc.). It is an effective and dependable option that promotes the growth of industrial automation.
IoT-based Remote Monitoring and Operation Solution Via IIoT Gateways And PLCs
Remote monitoring solution by IIoT gateway and PLCs are mainly composed of two major components:
Industrial gateways: interface with PLC or collector, gather data from industrial equipment, enable remote monitoring and intelligent control are the two parts of the solution.
Cloud platform for IIoT applications:Â stores, processes, and analyzes data that smart gateways upload to various locations; it can be displayed on a big screen to realize equipment management, maintenance work order management, remote operation and maintenance, big data analysis, etc.
In general, the industrial gateway may typically connect to and collect data from PLCs downlink, and transport data to clouds uplink to enable remote equipment administration and debugging.
Final Words
The Industrial Internet of Things has grown to be a significant force in the promotion of industrial automation as a result of the ongoing development of technology. In many industries, including equipment production, sewage treatment, animal husbandry, HVAC, refrigeration, transportation, etc., professional industrial IoT solutions are employed extensively. These technologies significantly increase equipment efficiency and reliability by enabling remote monitoring and administration of industrial equipment using PLC technology.
The Industrial Internet of Things will have to deal with more difficult and tough jobs in the future. It will increasingly rely on data analysis and artificial intelligence technology as the digital age progresses in order to achieve more intelligent and adaptive operation, maintenance, and management. Additionally, to respond to changing industrial surroundings and equipment, IIoT will need more adaptable and scalable solutions as industrial equipment keeps getting upgraded.
