Siemens 6ES7653-2CX01-0XE0 IM 653-2 | PROFIBUS DP Master, Redundant, S7-400H

Siemens 6ES7653-2CX01-0XE0 module specifications. SIMATIC S7-400 IM 653-2 interface module, PROFIBUS DP master, for redundant S7-400H systems.

Product Overview

The Siemens 6ES7653-2CX01-0XE0 is an IM 653-2 interface module for the SIMATIC S7-400H redundant automation system. It serves as a PROFIBUS DP master interface, enabling redundant communication between the fault-tolerant S7-400H CPU pair and PROFIBUS DP field devices. The module features two independent PROFIBUS DP interfaces (IF1 and IF2) and is designed for installation in the central controller rack of a high-availability system.

Technical Specifications

Key Features

• Redundant PROFIBUS DP Master:​ Two independent PROFIBUS interfaces for fault-tolerant communication

• S7-400H Compatibility:​ Specifically designed for high-availability redundant systems

• High Transmission Speed:​ Supports full PROFIBUS DP range up to 12 Mbit/s

• Y-Link Ready:​ Supports connection to single-channel slaves via PROFIBUS DP Y-Link

• Comprehensive Diagnostics:​ Front-panel LEDs for rapid troubleshooting

• Single-Width Module:​ Saves rack space in high-density configurations

• Hot-Swappable:​ Can be replaced during operation (in suitable S7-400 racks)

• Global Certifications:​ Approved for worldwide use, including hazardous areas

Applications

• PROFIBUS DP master interface for S7-400H redundant automation systems

• High-availability process control in oil & gas, chemical, and power industries

• Fault-tolerant communication with distributed I/O, drives, and field devices

• Connection of single-channel DP slaves via Y-Link in redundant architectures

• Safety-instrumented systems requiring high communication availability

Important Notes

1. This module requires an S7-400H system consisting of a redundant CPU pair (e.g., CPU 41x-H) and a compatible rack (e.g., UR2H).

2. One IM 653-2 module is required per CPU in the redundant pair (two modules total per S7-400H system).

3. Configuration requires STEP 7 V5.x or TIA Portal with appropriate S7-400H support package.

4. The module does not include a bus connector; 9-pin D-sub connectors must be ordered separately.

5. For standard (non-redundant) applications, the IM 467 series is recommended instead.
