Bridging Legacy Factory Equipment to Modern IIoT with 5G RedCap
Customer Profile:
An International System Integrator Specializing in Factory Automation and Predictive Maintenance
The Challenge: The "Brownfield" Data Silo in High-Noise Environments
A major automotive parts manufacturer sought to digitalize their production lines to implement predictive maintenance. The critical barrier was their "brownfield" environment: a factory floor populated by legacy Programmable Logic Controllers (PLCs) and CNC machines that communicated exclusively via older, isolated serial protocols. These machines lacked ethernet ports and could not integrate with the modern cloud architecture. Furthermore, the physical environment presented severe challenges. High-voltage induction motors and robotic welding equipment generated massive electromagnetic interference (EMI). Standard networking equipment introduced to this environment suffered immediate data corruption, port failures, and frequent hardware crashes due to industrial power grid instability.
The Solution: Seamless Protocol Conversion with the MOFIU SG100-5G RedCap
The system integrator selected the MOFIU SG100-5G RedCap Industrial Gateway (Model: SG100-5A40) as the critical translation and routing node, installing it directly onto the DIN rails inside the robotic control cabinets.
Legacy Serial to IP Protocol Translation: The SG100 serves as the vital bridge between legacy hardware and modern data servers. Utilizing its built-in, galvanically isolated RS485 and RS232 interfaces, the gateway connects directly to the legacy PLCs. It utilizes its internal routing logic to instantly translate older industrial serial protocols (such as Modbus RTU) into modern, IP-based MQTT protocols, normalizing raw telemetry (temperature, vibration, fault codes) for the central SCADA system.
Next-Generation 5G RedCap Low-Latency Networking: To handle the synchronized data flow from hundreds of machines, the SG100 utilizes the latest 5G RedCap technology. This provides the perfect balance of 5G reliability and microsecond latency (essential for critical factory alerts) without the excessive power consumption of traditional eMBB 5G modules.
Exceptional EMC/EMI Immunity: Designed for extreme industrial environments, the SG100 features 1.5 KV RMS ethernet isolation and 15 KV ESD protection on its serial ports. Its hardened aluminum IP30 chassis protects the internal circuitry from high-voltage spikes, ensuring uninterrupted data transmission even when installed millimeters away from high-power industrial servo drives.
The Benefits: Non-Intrusive Modernization and Actionable Intelligence
The manufacturer successfully retrofitted their existing factory equipment for real-time IIoT monitoring without altering core production logic. Operating on a highly stable 12V/2A industrial power supply (supporting 9-48 VDC), the SG100-5G RedCap eliminated data loss caused by factory power transients, allowing engineers to accurately predict machine wear and prevent catastrophic production halts.
