Modbus Communication Remote Data Acquisition IO Module: Which PLC Devices Can Be Collected

The remote data acquisition IO module introduced by Wutongbolian is an IoT device designed for remote communication and data collection.

 It supports LORA wireless transmission, 4G data uploading to the cloud, multi-channel IO data collection, Modbus RTU protocol, and wireless 485 transparent transmission. This module enables data collection and Modbus protocol communication from PLCs such as Siemens, Mitsubishi, Omron, Schneider, Delta, and Inovance. It is suitable for industries including mining, oil wells, water conservancy monitoring, smart agriculture, intelligent transportation, smart factories, and industrial control.

Application Scenarios

1. By deploying sensors and monitoring equipment within rural sewage treatment stations, data such as water quality parameters, temperature, and pressure can be collected.

    This enables real-time monitoring and visual analysis of sewage treatment equipment. Furthermore, data analysis can be utilized to optimize the operational parameters and treatment efficiency of sewage treatment equipment, enhancing management levels.

2. Through PLC data collection from equipment within sewage treatment plants, process configurations such as equipment runtime, pump switches, and motor start/stop statuses can be monitored.

    This facilitates intelligent alarms for equipment status and operational parameters, and leverages platform maintenance functions for effective cost reduction and improved maintenance efficiency.

3. Fire control PLC cabinets and sensors in pump station rooms can be integrated into the system, enabling online monitoring and over-limit alarms for data such as water immersion, smoke, gas concentration, temperature, and humidity.

    Notifications can be sent via WeChat, SMS, email, or audible/visual alarms, allowing for timely remote control of fire control equipment like sprinklers and ventilation systems to prevent accidents or mitigate their impact.
