PLCs, Power Supplies & Others

The Schneider 499NOS17100 operates as a managed Ethernet switch within the ConneXium family for Modicon automation systems. This device provides advanced network switching capabilities for industrial control networks requiring reliability and performance. It consequently enables deterministic communication between PLCs, HMIs, and other Ethernet devices.

Physical Characteristics and Build Quality

Engineers designed this switch in a rugged metal housing suitable for DIN rail mounting in control panels. The unit measures approximately 14 centimeters in height, 7 centimeters in width, and 11 centimeters in depth. Its total weight reaches roughly 0.8 kilograms, reflecting robust construction for industrial environments. The compact form factor allows installation in space-constrained enclosures.

Technical Specifications

Port Configuration and Flexibility

The 499NOS17100 provides sixteen copper ports for connecting local automation devices within the panel. Each copper port supports 10/100 Mbps auto-negotiation for compatibility with various equipment. The single fiber port enables long-distance connections to remote panels or control rooms. Consequently, this switch accommodates both local and remote network requirements.

Fiber Optic Connectivity

The integrated 100BASE-FX multimode fiber port extends network reach beyond copper limitations. SC-type connectors provide secure termination with low insertion loss for reliable transmission. Fiber supports distances up to 2 kilometers between switches for distributed architectures. This capability proves essential for large facilities with separated control equipment.

Managed Switching Features

As a managed switch, the Schneider 499NOS17100 offers advanced configuration options for network optimization. VLAN support segments network traffic for improved security and performance. QoS prioritizes time-critical automation traffic over less urgent data. SNMP management enables integration with network monitoring systems for proactive maintenance.

Network Redundancy

Built-in redundancy protocols ensure continuous communication even during cable or device failures. Rapid Spanning Tree Protocol provides loop-free topology with fast convergence times. Rapid Ring technology enables recovery in under 50 milliseconds for critical applications. These features maintain network availability for demanding industrial processes.

Diagnostics and Troubleshooting

The switch includes comprehensive diagnostic tools for network problem resolution. Port mirroring allows traffic analysis using external monitoring equipment. Built-in ping testing verifies connectivity to specific network devices. Cable diagnostics identify wiring faults like opens or shorts for rapid correction.

Industrial-Grade Construction

Engineers designed this ConneXium switch specifically for harsh industrial environments. The metal housing provides excellent heat dissipation and mechanical protection. Wide temperature tolerance ensures operation in unenclosed or unconditioned spaces. Industrial EMI immunity prevents communication errors from nearby motor drives or contactors.

Power Supply Requirements

The switch operates from 24 VDC industrial power supplies common in automation panels. It accepts 18 to 32 VDC input for tolerance of supply variations. A redundant power input option allows connection to two independent supplies for high availability. The alarm relay activates on power failure for immediate operator notification.

Status Indication

Front-panel LEDs provide comprehensive status information for rapid troubleshooting. Power LED indicates proper supply voltage to the switch. Each port has link/activity LEDs showing connection status and data traffic. System alarm LED illuminates when the switch detects internal or network faults.
