Product Details

The ProSoft PLX82-MBTCP-PNC is a DIN-rail mounted dual galvanically isolated Ethernet gateway, designed to enable Modbus TCP controllers to operate as a PROFINET IO controller and directly manage PROFINET RT field devices. It acts as a high-performance protocol bridge for bidirectional real-time cyclic and acyclic data exchange between Modbus TCP control systems and PROFINET fieldbus devices, supporting cross-brand automation integration for process and discrete manufacturing. The gateway can control up to 36 independent PROFINET RT nodes, including remote IO modules, variable frequency drives, valve actuators, HMIs and other PROFINET-compliant automation equipment. The two electrically isolated Ethernet ports separate the Modbus TCP control subnet and PROFINET field subnet, preventing IP conflicts, strengthening network security and eliminating the need to reconfigure IP addresses of existing on-site devices. It is fully certified to PROFINET v2 Class A standard, ensuring reliable compatibility with mainstream PROFINET devices from multiple manufacturers. The gateway supports large I/O data transmission, with up to 3840 bytes input and 3840 bytes output cyclic data capacity, and supports flexible register mapping, Enron Daniels floating-point format for Modbus data conversion to match different host controller data structures. It is configured through ProSoft Configuration Builder software, users can set polling rates, timeout rules and fault response logic conveniently. An optional SD card slot is reserved for configuration backup, fast restoration and configuration cloning during hardware replacement, greatly reducing production downtime during field maintenance. The gateway runs independently of the PLC scan cycle, so PROFINET device polling, real-time control output and data forwarding will not occupy host controller resources or interfere with the original control logic. It provides complete diagnostic tags for PROFINET device online status, cyclic communication health, connection timeout and fault codes, which can be read by Modbus master and displayed on HMI or SCADA platforms for rapid troubleshooting. A conformal coated version is optional for humid, dusty and corrosive industrial environments. This model is widely adopted in factory automation retrofits, packaging machinery, automotive assembly lines, chemical process control and skid-mounted equipment upgrade projects.

This gateway adopts rugged metal housing for standard DIN rail installation. It is equipped with two 10/100Mbps shielded RJ45 Ethernet ports with 1500Vrms isolation, accepts 10VDC to 36VDC wide-range DC power supply with 24VDC nominal input, maximum current consumption is 610mA. LED indicators display power status, module fault, Modbus TCP link and PROFINET bus activity for convenient on-site inspection. The operating temperature range is 0°C to 50°C, storage temperature ranges from -10°C to 70°C, relative humidity 5% to 95% non-condensing. It complies with IEC 60068 shock and vibration standards, and has obtained PROFINET certification. It supports remote configuration, online firmware upgrade and configuration backup for long-term field maintenance.

This Modbus TCP to PROFINET controller gateway is widely applied in automotive production lines, packaging automation, chemical process skids, material handling systems and factory modernization renovation projects. It allows Modbus TCP PLCs and PACs to directly perform real-time control over PROFINET field devices, realizing seamless interconnection between Modbus-based control systems and Siemens PROFINET field networks. As a reliable cross-protocol conversion spare part, the PLX82-MBTCP-PNC retains original field wiring and PROFINET devices and effectively reduces the renovation cost of multi-brand industrial control system integration.
