Case study of PLC Data Acquisition monitoring project for digital transformation of hydrogen refueling station in steel plant group

The digital transformation project under a certain steel group in Tianjin mainly addresses the Data Acquisition requirements encountered during the digital transformation process of hydrogen refueling stations in large steel mills in Tianjin. Key project requirements: The PLC equipment is already running and needs to collect data without modifying the program or affecting the operation of the PLC.

2. Requirement description

The five hydrogen refueling stations and one hydrogen production station constructed by the steel plant have some PLCs (brands including Siemens,ABB）The customer wishes to complete the PLCData Acquisitionwithout modifying the program and upload it to the platform for data display and monitoring via 4G.

2、 Scheme Introduction

1. Introduction to the Plan

Adopting data acquisition IoT PLC Data AcquisitionGateway（DAQ-GP-DPUPLCBOX）By connecting the device to the PLC through a network cable, the operating data of the PLC can be read. Users do not need to understand the existing program of the PLC, nor do they need to modify the PLC program. They only need to provide the internal program point table of the PLC. The module transmits the collected data to a remote server or cloud platform through 4G.

Project implementation and operation status

1. Operation status

At present, the equipment has been debugged and the temperature, pressure, liquid level and other data in the on-site PLC have been collected through Gateway and stably uploaded to the cloud platform. Customers can control the overall operation of the on-site equipment without going to the site and maintain the equipment based on the data.

summary

When the PLC code cannot be provided or the PLC program cannot be modified on the already running production line, this Data Acquisition Gateway (DAQ-GP-DPUBOX) can be used to collect data from the PLC. The PLC data register address, data type, etc. can be freely configured without programming or secondary development. Multiple communication methods such as 4G and wired network can be selected to communicate with the local area network/cloud platform. This Gateway supports the vast majority of PLCs on the market, such as Siemens, Mitsubishi, Omron, ABB, etc., and can easily provide PLC data to themMES/Industrial software such as SCDADA/ERP.
