Siemens 6ES74681DB000AA0

Technical Parameters

Diagnostic Granularity

Provides hierarchical diagnostics, including channel-specific error flagging (e.g., cable breaks, signal loss) and module-level status reporting via STEP 7's hardware configuration interface.

Redundancy Capability

Enables redundant system configurations with automatic switchover (<100 ms) when paired with complementary modules (e.g., IM 460-1), though redundancy firmware requires separate licensing.

EMC Robustness

Complies with IEC 61000-6-2 (industrial immunity) and IEC 61000-6-4 (emission standards), tested for operation in environments with 10 V/m RF interference up to 1 GHz.

Mechanical Configuration Flexibility

Allows vertical or horizontal DIN rail mounting without airflow restrictions, but requires a 40 mm clearance from adjacent heat-generating components (>5 W).

Functional Features

Siemens 6ES74681DB00-0AA0 is convincing with multi-protocol communication and real-time intensive handling of data:

Dual-Channel PROFIBUS DP Support – Ability to communicate with 124 devices (eg: Siemens S7-300 PLCs [6ES7318-3EL01-0AB0], remote I/O modules) at the same time, minimizing delay in high-speed packaging applications.

Diagnostic LED for Instant Identification: Instant indication of a fault, such as local network error and voltage drop to ensure food processing lines have no downtime.

Plug and play setup: The Siemens 6ES74681DB000AA0 is suitable for TIA Portal V18 where drag& drop parameterization makes for easy engineering in water treatment SCADA systems.

Associated Equipment
