PLCs, Power Supplies & Others

This Ethernet interface module connects programmable controllers to standard TCP/IP networks. It enables data exchange between control systems and enterprise-level information networks. The unit supports both cyclic and event-driven communication modes.

Technical Specifications

Mechanical Design and Form Factor

This module comes in a compact 30 mm wide housing for efficient backplane utilization. Its lightweight design weighs only 0.12 kilograms. The device slides directly into dedicated slots within the controller rack. A locking mechanism ensures secure seating and reliable electrical contact.

Power Supply and Electrical Characteristics

The module draws its operating power from the 5 V DC backplane supply. It consumes a maximum of 500 milliamperes during intensive network activity. This low power consumption minimizes heat generation within the rack. The module does not require an external power source.

Network Connectivity and Communication Protocols

An RJ45 port provides physical connectivity to standard Ethernet networks. The device supports both 10Base-T and 100Base-TX transmission speeds. It automatically negotiates the optimal speed with the connected switch. The module handles TCP/IP, UDP/IP, and ICMP protocols for versatile networking. It also supports Modbus TCP for industrial communication with SCADA systems.

Data Handling and Session Management

The module maintains up to eight simultaneous communication sessions. This capacity allows multiple clients to access controller data concurrently. The receive buffer stores 8 KB of incoming data. The transmit buffer holds 4 KB of outgoing packets. These buffers ensure smooth data flow during network bursts.

Diagnostic Features and Status Monitoring

Four front-panel LEDs provide clear visual feedback on network activity. The Link LED indicates a valid physical connection to the network. The Speed LED shows whether the link runs at 10 or 100 Mbit/s. The Active LED blinks during data transmission or reception. The Error LED signals any communication or configuration faults.

Energy Storage and Reliability Features

The module integrates capacitors for brief power ride-through during backplane transients. These capacitors maintain operation for approximately 10 milliseconds. This short hold-up prevents communication resets during minor voltage fluctuations. The device also includes a watchdog timer for automatic recovery from software lock-ups.

Configuration and Setup

Users can configure all network parameters via the backplane interface. The module stores its IP address, subnet mask, and gateway settings in non-volatile memory. An onboard web server provides a browser-based configuration page. This interface simplifies setup without requiring special software tools.

Application Environments

This interface module suits a broad spectrum of industrial networking applications. It works effectively in manufacturing plants, process facilities, and utility installations. The device also performs well in building management and warehouse automation systems. Its operating temperature range covers 0°C to +55°C.
