The PN1-D11PM is a professional-grade Profinet to Modbus RTU gateway specifically designed for seamless connectivity between Modbus devices and Profinet networks. Employing advanced data mapping technology, it accurately maps Modbus data to the Profinet protocol, achieving perfect conversion between the two mainstream industrial communication protocols. Users can quickly integrate Modbus devices without writing complex code. Through standard GSD file integration, users can easily complete configuration within familiar STEP 7 or TIA Portal software environments, significantly reducing technical barriers and operating costs.
Key Technical Features
1. Standard Profinet Protocol Communication
The PN1-D11PM enables real-time and accurate conversion between Profinet and Modbus RTU protocols. Supporting the standard Profinet RT protocol, the communication cycle reaches 4ms, fully meeting the real-time requirements of industrial applications. It supports the entire Siemens PLC series (200/300/1200/1500) and TIA Portal/SETP 7 host computer configuration.
2. Intuitive Memory Mapping Design
Unlike the complex configurations of traditional gateway products, the PN1-D11PM provides an intuitive and clear memory mapping relationship. Users can directly query and modify the mapping relationship through STEP 7 or TIA Portal software, enabling flexible data configuration and real-time monitoring.
3. Powerful Multi-Node Support Capability
The PN1-D11PM provides one RS485 interface, supporting simultaneous connections of up to 32 Modbus command nodes. This feature allows a single gateway to manage multiple Modbus devices simultaneously, greatly improving system integration density and cost-effectiveness.
4. Real-time Status Monitoring Function
The product integrates a status monitoring function, allowing real-time querying of the connection status of Modbus devices. By loading status bytes, users can intuitively understand the online status, communication quality, and other key information of each device.
This real-time monitoring capability not only improves system maintainability but also provides data support for preventative maintenance. Maintenance personnel can promptly detect and handle communication faults, avoiding production interruptions caused by equipment failures.
5. Industrial-Grade Protection Design
The PN1-D11PM product surface is coated with a conformal coating, possessing excellent properties of "anti-mildew," "anti-moisture," and "anti-salt spray." This protective design enables the product to operate stably in various harsh industrial environments, including humid basements and corrosive gas environments.
The product's protection level and material selection have undergone rigorous industrial environmental testing, ensuring reliable operation within a wide temperature range of -40℃ to +85℃.

Application Scenarios and Solutions
Smart Manufacturing Production Lines
In modern smart manufacturing production lines, it is often necessary to integrate equipment from different manufacturers into a unified production control system. The PN1-D11PM can quickly connect legacy Modbus devices to the new Profinet network, providing a cost-effective solution for the intelligent transformation of production lines.
Building Automation Systems
Modern building automation systems require unified management and control of multiple subsystems such as lighting, air conditioning, and security. Due to historical reasons, different subsystems may use different communication protocols. The PN1-D11PM can act as a protocol conversion hub, enabling data exchange and control coordination between subsystems.
Especially in old building renovation projects, many existing devices use the Modbus protocol. By installing the PN1-D11PM gateway, these devices can be quickly integrated into the new building automation system, avoiding the high costs associated with equipment replacement.
Energy Management Systems
Energy management systems require centralized monitoring and control of energy-consuming devices distributed across different areas. The PN1-D11PM can connect to various Modbus protocol-compliant energy consumption monitoring devices such as electricity meters, water meters, and gas meters, transmitting data in real time to a Profinet-based energy management platform.
Environmental Monitoring Network
In environmental monitoring applications, it is necessary to aggregate sensor data from various monitoring points to a central control platform. The PN1-D11PM can act as a field data acquisition gateway, converting Modbus protocol environmental sensor data into Profinet format for transmission to the environmental monitoring center.
This application has broad prospects in industrial parks, urban environmental monitoring, and agricultural greenhouse monitoring.
