PLC Data Acquisition Solution for a Flour Production Line

Published: 2026-05-06 11:26:56

A flour mill originally operated multiple PLC-controlled automated production lines, along with a central supervisory HMI/SCADA system for centralized monitoring, report generation, recipe management, data traceability, and alarm handling—all managed by control room operators. The factory now aims to build a 5G-enabled workshop, requiring 5G connectivity and remote monitoring of production line equipment to improve efficiency and management.

 

WideIOT deploys industrial IoT gateways inside PLC control cabinets. The gateways collect production line data from PLCs via serial ports or Ethernet—including equipment status, feed weight, drying temperature and humidity, and storage tank levels—and transmit it over 5G to a digital workshop management platform. This enables remote monitoring, alerting, management, control, and data analysis, providing reliable data support for cost reduction, efficiency improvement, and intelligent plant management.

Key Features

1. Enables comprehensive monitoring and centralized management of key equipment such as silo distributors, electronic belt scales, pre-cleaners, bucket elevators, and vibrating feeders. A visualized equipment dashboard provides quick access to model numbers, operating status, process parameters, fault signals, and more.

 

2. Monitors raw material batching, silo conditions, material levels, and equipment fault signals in real time. When abnormal data is detected, automatic alerts are sent via WeChat, SMS, or email to management at various levels, allowing for rapid fault location, diagnosis, and corrective action.

 

3. Authorized personnel can remotely control equipment to ensure production safety. Engineers can also remotely debug, program, and upload/download PLC programs as needed.

 

4. Establishes an information-based, visualized, and traceable maintenance management system. It helps optimize workforce and material allocation, manage digital work orders, and centralize information such as operation logs, responsible personnel, and task status—extending equipment life and ensuring operational safety.
