PLCs, Power Supplies & Others

The Schneider KOS130 communication unit serves as a dedicated fieldbus gateway for Modicon M340 and M580 automation platforms. This interface module enables seamless data exchange between the controller and remote I/O networks. Its compact enclosure measures 105 mm in height, 60 mm in width, and 85 mm in depth. The unit weighs approximately 0.32 kg, making it suitable for space-efficient cabinet layouts.

Technical Specifications

Protocol Support and Network Flexibility

The KOS130 handles three major industrial protocols simultaneously without requiring firmware switching. Users can configure the unit for Modbus TCP connections over Ethernet or serial-based Modbus RTU networks. The gateway also supports Profibus DP communication for integrating third-party field devices. This multi-protocol capability simplifies system upgrades and reduces the need for additional hardware.

Data Handling and Performance Metrics

This gateway processes up to 512 bytes of input and output data per exchange cycle. It supports a maximum of 64 slave devices on a single network, scaling well for medium-sized control systems. The unit maintains a typical cycle time of under 5 ms for most deterministic applications. Such responsiveness ensures reliable synchronization between the controller and connected actuators or sensors.

Physical Interfaces and Connectivity

An RJ45 Ethernet port provides the primary connection for Modbus TCP communications. A SUB-D 9 serial port supports RS-232 and RS-485 standards for legacy device integration. The KOS130 also includes a separate 24 V DC power input terminal for reliable energy supply. LED indicators on the front panel display the operating status of each communication channel. These lights assist technicians in verifying network health and signal activity during routine inspections.

System Integration and Configuration

Engineers can configure the KOS130 through a web-based interface or directly via the Modicon programming software. The unit supports automatic device discovery for quick network setup and reduced commissioning time. It also stores configuration parameters in non-volatile memory, preserving settings during power loss. This feature prevents data loss and allows for rapid system recovery after unexpected shutdowns.

Environmental Suitability and Durability

The module operates reliably within a 0°C to 60°C ambient temperature range. Its IP20-rated housing offers adequate protection against dust and accidental contact in control cabinets. The 1500 V DC isolation barrier protects the controller side from voltage spikes originating in the field network. Such isolation ensures long-term reliability in environments with frequent electrical disturbances.

Installation and Maintenance Features

Mount the KOS130 onto a standard 35 mm DIN rail using the integrated clip mechanism. Its compact width of 60 mm preserves valuable panel space for additional components. The removable terminal blocks simplify wiring replacement and module exchange. Regular firmware updates are available via the Ethernet port, keeping the unit compatible with evolving protocols.
