Technical Parameters
Communication Protocols
Supports PROFIBUS DP-V1 and PROFINET IRT for deterministic real-time communication, with baud rates up to 12 Mbps for industrial networking.
Processing Speed
Embedded co-processor for signal filtering and scaling, reducing CPU load by up to 35% during high-speed data acquisition.
Memory Allocation
Onboard non-volatile memory (8 MB) for storing parameter sets and calibration data, accessible via cyclic/acyclic data exchange.
Modular Expansion
Compatible with ET 200M distributed I/O systems, enabling hybrid configurations with up to 16 additional modules per interface.
Environmental Resilience
Operates in temperatures from -25°C to +60°C without derating, and withstands 95% relative humidity (non-condensing) per IEC 60068-2-30.
Safety Integration
Complies with IEC 61508 SIL 2 for functional safety applications, featuring hardware-based watchdog circuits and dual-channel redundancy.
Power Supply Flexibility
Accepts 24V DC ±30% input with reverse polarity protection, consuming ≤5W during peak operation.
Key Features
Redundant and scalable to address the largest breadth of automation needs, the Siemens 6ES74000HR544AB0:
Dual-CPU Redundant: With 2 synchronized CPU 414-5H processors, this system will automatically swap over to the backup CPU in the occurrence of a system failure, which ensures no extended downtime.
Real Time Sync: includes integrated 10M sync modules within 1M sync cables for real time syncing of data between racks, essential for fast processes such as automotive assembly lines.
Modular Simplicity: Able to accommodate a maximum of 18 I/O modules, a communication processor (e.g., CP 443-1) and two redundant power supplies (PS 405/407), the UR2-H rack allows systems to be easily expanded.
Compatible Components
The Siemens 6ES74000HR544AB0 works together perfectly with Siemens automation technology:
AC Power Supplies:Two PS 405 10A single units (24/48/60V DC) keep the system stable even with tremendous ambient voltage instability or power failure situations.
I/O Moduels: Suitable for S7-400 series analog/digital modules for accurate control of sensors/actuators in large systems.
SCADA Integration: Interfaces with WinCC SCADA systems for centralized monitoring and diagnostics, ideal for large-scale energy or chemical plants.
Industry Applications
The Siemens 6ES74000HR544AB0 addresses challenges across multiple sectors:
Oil & Gas: Controls safety shutdown systems (SIS) in refineries, where redundancy prevents catastrophic failures during pipeline leaks or pressure surges.
Automotive Manufacturing: Synchronizes robotic welding arms and conveyor systems, reducing production halts caused by PLC failures.
Renewable Energy: Manages wind turbine pitch control and grid synchronization, ensuring uninterrupted power generation even in extreme weather conditions.
