Issue
There are two available solutions to implement time stamping with EcoStruxure Control Expert, both methods are easy to implement and can be selected for use in almost any circumstance.
- Applicative – A function block is required for third-party SCADA to convert and read the information
- System – No programming is required (some components are needed)
System and Applicative time stamping modes are exclusive in the same EcoStruxure Control Expert application running in the controllers. In this article, we will investigate the System Time Stamping solution.
Resolution
System Time Stamping provides a consistent SOE (sequence of events), time stamped at the source, to allow the user to analyse the source of abnormal behaviour in a distributed automation system. The SOE is displayed in an alarm summary or SOE page of a client (such as a SCADA). Each source of time stamped event of the SOE is a discrete I/O value change (transition) detected by a time stamping module, this event is then passed through to OFS and straight to the SCADA.
