Precision Time Synchronization
The 140ERT85410 functions as a time stamp module for the Schneider Electric Modicon Quantum system. This unit provides precise time synchronization for distributed control applications. It accepts GPS or IRIG-B signals as external time references. The module then distributes this synchronized time across the backplane to other modules. Consequently, it enables accurate event sequencing and data correlation across the entire system.

Synchronization and Event Logging
The 140ERT85410 logs time-stamped events with 1 ms resolution for sequence-of-events analysis. It stores up to 256 events in a dedicated FIFO buffer for later retrieval. The module automatically adjusts for daylight saving time if configured accordingly. Users can force manual time setting through the programming software. The integrated real-time clock operates independently, maintaining accurate time during communication interruptions.
Integration and Diagnostics
This module seamlessly integrates with Quantum PLCs and SCADA systems. It delivers synchronized timestamps to other modules and the CPU over the backplane. Users can easily commission the 140ERT85410 via the Unity Pro software environment.
