Siemens 6ES74002JA100AA0

Technical Parameters

Fault-Tolerant Communication

Enables redundant data exchange between S7-400H CPUs with a synchronization time of <15 ms, ensuring seamless failover during PLC split scenarios (e.g., fiber-optic link breaks).

Dual-Channel Fiber-Optic Interface

Supports 100 Mbps full-duplex communication via two independent FO ports (ST connector type), with a maximum cable length of 3 km (62.5/125 μm multimode fiber).

Hardware-Based Clock Sync

Synchronizes redundant CPUs with a precision of ±0.5 ms using proprietary timestamping, independent of network load or software cycles.

Diagnostic Buffer Depth

Stores up to 1,000 system events (e.g., switchovers, sync errors) with microsecond-level timestamps for root-cause analysis in fault-tolerant systems.

Redundant Power Supply Integration

Accepts dual 24 V DC feeds (18–32 V range) with automatic cross-circuit monitoring and load balancing, minimizing downtime during power disruptions.

Firmware Redundancy Management

Validates firmware consistency between paired CPUs during startup; triggers alarms for version mismatches ≥V6.0.

Dynamic Bandwidth Allocation

Prioritizes control data (e.g., process values) over diagnostic traffic during high-load periods, configurable via STEP 7 redundancy settings.
