1.8. Sequence of Events Characteristics

The input module automatically measures the field-input voltage, compares the value to the

configurable thresholds, and determines the state of the field input. An event occurs when the input

transitions from one state to another. When an input changes state, the on-board real-time clock value

is recorded. When the TMR Processor next reads data from the input module, the input state and real-

time clock values are retrieved. The TMR Processor uses this data to log the input state change into

the system Sequence of Events (SOE) log. The user may configure each input to be included in the

system SOE log. Full details of SOE are contained in PD-8013 – Trusted

SOE and Process

Historian.
