SIEMENS ET100E/S30824-Q61-X100-4/W30824-Q0061-C008 Communication Interface Module

Product Dimensions：

The Siemens ET100E (W30824-Q0061-X100 / W30824-Q0061-C008) is a legacy industrial automation component, specifically part of the SIMATIC S5 family. It serves as an interface module for the ET 100E distributed I/O system, which was widely used to connect remote sensors and actuators to a central PLC.

1. Product Detailed Description

The ET100E series was designed as a rugged, decentralized periphery system. The W30824-Q0061-X100 (often cross-referenced with the C008 designation) acts as the “brain” of the remote station. It facilitates communication between the central controller (like an S5-115U or S5-135U) and the local I/O modules via a fieldbus connection.

Despite being a legacy part, it remains critical for maintaining older manufacturing lines in industries like automotive, chemical processing, and power generation.

3. Key Product Advantages

• High Reliability: Built to the rigorous standards of the SIMATIC S5 era, known for lasting decades in harsh environments.

• Decentralization: Reduces wiring costs significantly by allowing I/O to be placed close to the machinery while the PLC stays in a central cabinet.

• Legacy Compatibility: Seamlessly integrates with existing S5 systems without requiring a full migration to S7 or TIA Portal.

• Rugged Design: Excellent electromagnetic compatibility (EMC) and vibration resistance.

4. Important Considerations & Precautions

⚠️ Note on Obsolescence: The ET100E series is a “legacy” or “discontinued” product. Original factory support from Siemens may be limited.

• Firmware Versions: Ensure the “X” or “C” version matches your existing module, as different revisions may have slight timing or compatibility differences.

• Static Electricity: When handling the module, always use an ESD (Electrostatic Discharge) wrist strap to avoid damaging the internal CMOS components.

• Power Supply Quality: Use a stabilized 24V DC power supply; voltage spikes can permanently damage the communication interface.

• Connection Integrity: Ensure that the bus connectors are properly tightened; loose connections in the ET100E system often lead to intermittent “Bus Fault” (BF) errors.

5. Typical Product Applications

• Automotive Assembly Lines: Controlling distributed robotic arms and sensors.

• Water Treatment Plants: Managing remote pump stations and flow meters across large facilities.

• Power Plants: Used in auxiliary control systems where S5 hardware is still the operational standard.

• Retrofitting & Spares: Used as a direct replacement part to avoid the high cost of upgrading an entire plant to modern S7-1500 systems.
