In the tide of Industry 4.0, many applications are realized by host computers and clouds, so PLC data acquisition is one of the most basic prerequisites.
How to realize PLC data acquisition
The current mainstream PLC data collection method is achieved through industrial gateways. Industrial gateways have powerful data collection capabilities and rich protocol libraries, supporting various types of PLC devices. After collecting data from PLC devices, they are converted into a standard format through protocol parsing, and then transmitted to the host computer or cloud through the network through MQTT or MODBUS protocol to realize data utilization.

How to choose a PLC data acquisition gateway?
Wutong Broadlink PLC Data Acquisition Gateway
When choosing a PLC data acquisition gateway, you should choose it based on the model of the PLC device you need to collect data from. Different models of PLCs have different interfaces and communication protocols. You need to consider whether the PLC data acquisition gateway can support the PLC devices you need to collect data from, and whether it supports the corresponding protocols (such as ModBus, OPC, CAN, ControlNet, DeviceNet, Profibus, Zigbee and other types of industrial protocols). Choose a suitable gateway manufacturer based on these requirements.
