1.8. Sequence of Events Characteristics
Each Boolean Variable can be configured for automatic Sequence of Events (SOE) logging. This
applies to the Input/Output Status and Line Fault Status variables. A Boolean variable is configured for
SOE during the variable definition in the Data Dictionary Editor. To select SOE, press the Extended
Button in the Boolean Variable Definition Dialog Box to open the Extended Definition Dialog. Then
check to box for Sequence of Events to enable the variable for automatic SOE logging.
During operation, the module automatically reports time-stamped change of state information for the
output data. The TMR Processor automatically logs change of state for configured SOE variables into
the system SOE Log. The SOE Log can be monitored and retrieved using the SOE and Process
Historian Package running on the EWS. This software package is described in PD-8013.
