Product Overview
The Siemens 6AG1400-1TA11-7AA0 SIPLUS S7-400 Rack UR1 is a rack component for SIMATIC S7-400 PLC systems. It provides the physical mounting structure and backplane connection for S7-400 modules installed in the control station.
The UR1 rack is used where multiple S7-400 system components need to be arranged in a centralized automation cabinet. Depending on the configured system, the rack can accommodate the CPU, power supply, communication modules, and other compatible S7-400 modules.
In an industrial control cabinet, the rack keeps the installed modules in their defined positions and establishes the internal electrical connection between them. It is therefore part of the basic hardware structure of an S7-400 automation station.
For replacement work, the complete 6AG1400-1TA11-7AA0 order number and the existing S7-400 hardware configuration should be checked before installation.

Product Features
- SIPLUS S7-400 rack component.
- UR1 rack configuration for SIMATIC S7-400 systems.
- Provides mounting positions for compatible S7-400 modules.
- Establishes the internal backplane connection between installed modules.
- Suitable for centralized PLC control cabinets.
- Applicable to S7-400 system installation, replacement, and expansion.
Working Principle
The 6AG1400-1TA11-7AA0 functions as the mechanical and electrical base for the S7-400 modules installed in the station. Each compatible module is mounted in its assigned position and connects to the rack backplane.
The backplane provides the internal electrical connection required for communication between the installed S7-400 modules. This allows the CPU, power supply, communication modules, and other system components to operate as an integrated PLC station.
The rack itself does not execute PLC logic or process field signals. Its function is to provide the physical structure and internal interconnection required by the active modules.
Role in S7-400 Control System
The UR1 rack forms the hardware foundation of a centralized S7-400 control station. It determines the physical arrangement of the modules and provides their internal backplane connections.
In a process control cabinet, the rack can be used to organize the central PLC hardware in a defined configuration. Keeping the modules in their intended positions also makes cabinet inspection, replacement, and maintenance easier.
When replacing a rack in an existing installation, maintaining the original module arrangement can help reduce configuration and wiring errors during recommissioning.
Industrial Applications
Process Automation
Used in S7-400 control cabinets for process monitoring and control applications.
Manufacturing Automation
Suitable for centralized PLC stations controlling production equipment and manufacturing processes.
Plant Utility Systems
Applicable to S7-400 installations used for pumps, compressors, water systems, HVAC equipment, and other plant utilities.
Control System Maintenance
Used when an existing S7-400 rack requires replacement or when a control cabinet is being refurbished or expanded.
Installation and Maintenance
Before installation, verify the complete 6AG1400-1TA11-7AA0 part number and confirm that the UR1 rack matches the existing S7-400 configuration.
Inspect the rack and backplane connection areas for contamination, mechanical damage, corrosion, or damaged contacts before installing the modules.
When replacing an existing rack, record the positions of the installed S7-400 modules before removal. Reinstall the modules according to the approved system configuration and ensure that each module is correctly seated.
After installation, check the power supply, CPU, communication modules, and other system components before returning the PLC station to operation.

Technical FAQs
What is the purpose of the Siemens 6AG1400-1TA11-7AA0 rack?
It provides the physical mounting structure and internal backplane connection for compatible S7-400 modules installed in the automation station.
What does the UR1 designation indicate?
UR1 identifies the rack type within the S7-400 rack system. The rack type must be matched with the intended S7-400 hardware configuration.
Does the rack itself perform PLC control functions?
No. The rack provides the mechanical and electrical infrastructure. PLC processing, communication, and I/O functions are performed by the corresponding active S7-400 modules installed in the rack.
What should be checked before replacing an S7-400 UR1 rack?
The complete order number, rack type, installed module arrangement, backplane connections, cabinet mounting arrangement, and overall S7-400 configuration should be checked before replacement.
