What are the benefits of PLC data collection?①

 

In the integration process of industrial automation and intelligent manufacturing, PLCs, as core control devices, carry critical production data. However, the diverse brands and complex protocols of on-site PLCs lead to difficulties in data interconnection, which restricts the digital transformation of enterprises. WideIOT Industrial Intelligent Gateways, with their core capabilities including protocol compatibility, edge computing, and secure transmission, serve as the hub for PLC data collection, bringing comprehensive value enhancement to enterprises.

 

I. Breaking Protocol Barriers to Achieve Full-Scenario Data Convergence

Industrial on-site PLCs come from various brands (e.g., Siemens, Mitsubishi) and adopt heterogeneous communication protocols (e.g., Modbus, Profinet), forming "data silos". Equipped with multiple industrial protocol drivers, WideIOT Industrial Intelligent Gateways are capable of compatible parsing of various protocols, acting as a "Protocol Translator".
With abundant serial ports and network ports, the gateways seamlessly connect to traditional serial-port PLCs and new-generation Ethernet PLCs, collect scattered data uniformly and convert them into standard formats such as MQTT and OPC UA. Without large-scale transformation of existing equipment, it enables data convergence of multi-brand PLCs, laying a solid data foundation for subsequent analysis and decision-making.

 

II. Edge Intelligent Preprocessing to Reduce Transmission Costs and Cloud Load

Raw PLC data contains a large amount of invalid information; direct transmission will occupy bandwidth and increase cloud load. WideIOT Industrial Intelligent Gateways feature powerful edge computing capabilities, which can perform precise preprocessing at the data source.
By virtue of the built-in edge computing engine, the gateways can realize functions such as data filtering, anomaly elimination, and alarm judgment, and only upload structured and valuable data. This not only reduces transmission costs and cloud load, but also improves processing efficiency. Meanwhile, the local response capability at the edge ensures uninterrupted monitoring even when the network is disconnected, guaranteeing data availability.

 

III. Multi-Dimensional Security Protection to Safeguard Industrial Data Transmission and Data Sovereignty

Industrial data is related to core confidential information, so secure transmission and data sovereignty are of vital importance. WideIOT Industrial Intelligent Gateways build a security protection system from multiple dimensions including physical isolation, transmission encryption, and permission control, ensuring the security of PLC data collection.
The gateways achieve physical isolation between OT and IT networks, constructing an industrial firewall to resist external attacks; they support VPN, SSL/TLS encryption and other mechanisms to ensure transmission security; they deeply support private deployment, allowing data to be aggregated to enterprise local servers or private clouds, thus ensuring data sovereignty and meeting high security compliance requirements.

What is an Industrial Gateway?

  In the era of Industry 4.0, where smart factories and interconnected systems dominate,   industrial gateways   have emerged as critical components for enabling seamless communication, data exchange, and automation across diverse industrial environments. But what exactly is an industrial gateway, and why is it indispensable in modern manufacturing and process control? This article explores its definition, functions, types, and real-world applications. Definition of an Industrial Gateway An   industrial gateway   is a specialized hardware or software device designed to bridge communication gaps between incompatible industrial networks, protocols, or devices. It acts as a translator and router, ensuring that data from legacy machinery, sensors, controllers, or cloud platforms can be understood and utilized by other systems. Unlike standard networking gateways, industrial gateways are built to withstand harsh environments (e.g., extreme temperatures, v...

IoT Solution for DCS Data Acquisition of Stackers and Reclaimers

图片
  In thermal power plants, stackers and reclaimers play a crucial role in storing and conveying raw materials. They execute various automated instructions through PLCs (Programmable Logic Controllers) and DCS (Distributed Control Systems), such as allowing stacking, allowing reclaiming, peripheral reclaiming operation, emergency shutdown of stackers and reclaimers, stacking operation, stacking faults, reclaiming faults, reclaiming circuit, and more. These instructions provide reliable assistance for enhancing production efficiency and management levels. To achieve DCS data acquisition and enable remote monitoring and precise management of stacking and reclaiming operations, WideIOT offers an IoT solution based on industrial smart gateways. By connecting to the central control room’s DCS, the gateway can adapt to protocols and perform data acquisition. The collected data is then transmitted to a remote monitoring cloud platform, enabling functions such as visual display, remote moni...

IoT Solution for Digital Transformation in Discrete Manufacturing Industry

图片
  For enterprises aiming to achieve smart manufacturing and digital transformation, the most challenging and core aspect lies in digitizing the production process.  This is particularly true in the discrete manufacturing sector, where products are often assembled from multiple components through a series of discontinuous processes. The production process involves numerous variables and uncertainties, all of which need to be captured and monitored. Taking the automotive manufacturing industry as an example, the production process includes stamping, welding, painting, and final assembly.  The equipment involved ranges from stamping machines, welding robots, painting robots, drying ovens, and assembly robots to ancillary PLCs, sensors, and instrumentation. Data such as temperature, pressure, flow rate, voltage, and current are crucial determinants of a vehicle's quality. In response, WideIOT provides data acquisition gateways that connect to PLCs, instrumenta...
