Main Functions and Technical Advantages
1. Industrial-grade Redundant Ring Network Management
The 6GK1503-3CC00 has a built-in MRP (Media Redundancy Protocol) client function, which can complete network fault switching within 200ms, ensuring uninterrupted PROFINET RT/IRT communication. It supports single-ring, multi-ring, and coupled-ring topologies, and can manage up to 50 ring network nodes, meeting the stringent high availability requirements of large production lines.
2. Flexible Networking with Hybrid Media
Unique 6-Electronic-Port + 2-Fiber-Port design supports hybrid deployment of copper and fiber optic cables:
- **RJ45 Interface**: Supports Auto MDI/MDI-X, adaptive straight-through/crossover cabling, simplifying field cabling.
- **SC Fiber-optic Interface**: Strong anti-electromagnetic interference capability, suitable for long-distance cross-workshop communication or areas prone to lightning strikes.
- **Cascading Capability**: Fiber-optic ports support networking with other OSM/ESM switches, extending network coverage.
Typical Application Scenarios
Automotive Welding Workshop
In robotic welding workstations, the 6GK1503-3CC00 acts as a field-level switch, connecting to the aggregation layer via fiber optic cable, and connecting 10-15 Siemens PLCs or robot controllers via electrical ports. The MRP ring network ensures that any link failure does not affect production cycle time, with a fault switching time of <50ms, avoiding workpiece scrap caused by sudden stops of welding robots.
Food and Beverage Packaging Line
Complies with FDA 21 CFR compliance requirements, can be installed with stainless steel DIN rails, and can be directly deployed outside the washing area. IP30 protection rating resists sugar powder and oil contamination, and the operating temperature range of -20°C to +70°C adapts to temperature variations from cold storage to sterilization machines. VLANs isolate the production network from the management network, ensuring the integrity of food safety data.
Distributed I/O in Cement Plants: In environments with high dust concentrations, fiber optic interfaces avoid the electromagnetic interference problems associated with traditional copper cables. Redundant ring networks connect remote I/O stations distributed across preheaters, rotary kilns, and grate coolers. A single point of failure does not affect the operation of the entire clinker production line, increasing system availability from 99% to 99.9%.
