I. PLC Gateway
PLC industrial gateways support mainstream industrial PLC device protocols, enabling easy internet access for industrial PLCs. This allows for remote acquisition of PLC operating data, facilitating remote PLC upgrades, diagnostics, monitoring, and big data-driven early warning systems. It serves as a type of intelligent transmission terminal device within the industrial internet platform. Using a PLC industrial gateway in a complete IoT solution allows for remote monitoring of real-time PLC data from various industrial devices. This data is then uploaded to a cloud data platform, ultimately enabling engineers to perform remote monitoring, maintenance, and diagnostics on the client side.
(I) The Importance of PLC Industrial Gateways
1. Enable remote control of industrial field equipment;
2. The PLC industrial gateway enables remote firmware upgrades and program downloads/uploads for devices, and can flexibly connect to various device management platforms;
3. Enable remote control of industrial field touchscreens and remote mapping of configuration screens;
4. The PLC industrial gateway can communicate remotely with multiple PLCs or touch screens simultaneously;
5. Enables hardware parsing of mainstream protocols for PLCs such as Siemens, Mitsubishi, Omron, Schneider Electric, Delta, Inovance, Hollysys, Panasonic, Yung-Hong, Haiwei, and MODBUS series;
6. The PLC industrial gateway enables remote PLC monitoring, remote PLC programming, remote PLC debugging, remote PLC upload/download, remote PLC control, PLC data acquisition, and remote PLC communication;
(II) What are the functions of a PLC gateway?
1. PLC industrial gateway with abundant interfaces and easy deployment:
It supports 4G, 3G, PPPoE, Wi-Fi networks, digital I/O input/output, and serial terminal communication, providing different access solutions for different application scenarios.
2. Intelligent analysis and efficient access:
It features an embedded protocol analyzer that supports mainstream industrial control protocols (Modbus/PPI/MPI/Profinet/Dvp/OPC, etc.) and customized proprietary protocols; it achieves local computation through policy rule calculation and application deployment and distribution, thereby improving the control capabilities and real-time performance of the device.
3. PLC industrial gateway pipeline transmission and data aggregation
Embedded with the WDCP (Web Connectivity Protocol), it enables standardized access for complex machine types in the field and aggregates data to the data center for computation and storage. It supports functions such as remotely reading gateway status, remotely controlling the gateway, remotely configuring devices and variables, remote deployment, remotely reading device data, and remotely writing device data.
II. PLC Data Acquisition Gateway
(I) What are the functions of a PLC data acquisition gateway?
1. Rich networking and interface functions, easy to deploy
It supports network access methods such as 5G/4G/3G/WIFI/Ethernet WAN/fiber optic, supports the access of devices such as network port/serial port/IO port/CAN port, supports LORA wireless transmission, disconnection reconnection and multi-network mutual backup functions.
2. Enhanced protocol parsing, intelligent data acquisition, and control.
It features an embedded protocol analyzer that supports mainstream industrial control protocols and customized proprietary protocols (such as PLC protocols, instrumentation protocols, power protocols, industrial robots, machine tools, etc.); and an embedded IoT-connected patented algorithm for efficient and stable data acquisition and control of various industrial equipment.
3. Data standardization and MQTT protocol access
The IoT-connected model standardizes data by requiring only variable points to convert it into JSON format and connects to cloud platforms via IoT standard protocols. This eliminates the differences between automation and information technology, as well as equipment variations, providing standardized data APIs for convenient and efficient development of Industry 4.0 systems.
(II) How to correctly use a PLC data acquisition gateway
By understanding its customers, Wutong Bolian utilizes its Penetrating Cloud Equipment Express system to remotely program and monitor the core PLC controller of CNC machinery. This enables remote monitoring of CNC machinery parameters, troubleshooting of system faults, and online data maintenance.
A PLC-based IoT-based remote maintenance system for CNC machinery allows for real-time online monitoring of the machinery's operation and detection of various faults, significantly improving the speed of repair when malfunctions occur. Therefore, applying this new control system to CNC machinery control and remote monitoring is a requirement for the intelligent and sophisticated development of modern CNC machinery.
