Description
Description
The Siemens 6ES5700-0LA11 is a robust 4-slot mounting rack engineered for the Simatic S5 PLC series. This subrack serves as the essential mechanical and electrical foundation for S5 systems, facilitating the integration of CPUs, power supplies, and various I/O or communication modules. It is specifically designed to provide a stable, vibration-resistant environment for critical control hardware, ensuring reliable communication across the system's backplane. This component is widely utilized in established industrial automation environments where long-term system stability and signal integrity are required.
Features
-
Modular Architecture: Provides 4 dedicated slots for flexible configuration of Simatic S5 components.
-
Signal Integrity: Passive backplane design minimizes impedance mismatches and cross-talk, supporting consistent data bus performance.
-
EMI Protection: Features an integrated grounding rail designed to mitigate high-frequency electromagnetic interference.
-
Industrial Durability: Constructed with an anodized aluminum profile for structural rigidity and protection against torsional stress.
-
Secure Mounting: Precision guide rails ensure modules are aligned correctly and locked securely to prevent intermittent connection failures.
Applications
This mounting rack is a standard choice for maintaining or upgrading legacy Simatic S5 automation systems. Typical applications include metal processing facilities, municipal water treatment and pumping stations, and petrochemical refining infrastructure where S5 controllers remain a core part of the process control loop.

Installation Guidelines
- Ensure the rack is mounted to a clean, vibration-dampened surface within a standard industrial enclosure.
- Always disconnect power to the system before inserting or removing modules from the rack to prevent electrical arcing or short-circuiting of the backplane pins.
- Verify that all modules are fully seated and secured via the provided locking mechanisms to ensure optimal electrical contact.
- Maintain proper grounding of the chassis to the main cabinet ground point to ensure effective EMI shielding.
- Allow for adequate ventilation around the rack to prevent heat buildup, adhering to the specified operating temperature range.
FAQ
Q: Is this rack compatible with all Simatic S5 modules?
A: This rack is designed for the standard Simatic S5 module form factor. Please verify your specific module series compatibility with the S5 backplane architecture before installation.
Q: Does this unit require external power?
A: No, the 6ES5700-0LA11 is a passive backplane. It distributes power provided by the S5 power supply module inserted into the rack.
