System Time Stamping Versus Applicative Time Stamping

System time stamping: All in one solution to benefit from at source time stamping, easy to start up without requiring any user programming. This solution requires either the OFS or the BME NUA 0100 V2.0 product in the architecture.

Applicative time stamping: Solution recommended when a 3rd party SCADA that does not support OPC DA or OPC UA interfaces is required. In this case, events are read by function blocks in the PLC application (with Control Expert software) and the events read are formatted to be sent to the SCADA. For more details on the applicative mode, refer to the EcoStruxure™ Control Expert, Applicative Time Stamping, User Guide.

NOTE: System and applicative time stamping modes are exclusive in the same Control Expert application running in the PLC.
NOTE: Only the system time stamping mode allows Modicon M580 CPU internal variable time stamping.
NOTE: Time stamping with 140 ERT 854 •0 modules can be used in both applicative and system modes, but this topic is not discussed in this guide. For more details on those modules, refer to the Quantum using EcoStruxure™ Control Expert, 140 ERT 854 10 Time Stamp Module, User Manual and the Quantum using EcoStruxure™ Control Expert, 140 ERT 854 20 Time Stamp Module, User Manual.
