SOE Service Parameters
The AADvance Workbench supports a Sequence of Events (SOE) service for boolean
variables. When a Sequence of Events service is defined, use the SOE tab of the
Variable dialog box to define the SOE properties:
 Falling-edge: the indication of whether the service detects a fall from TRUE to
FALSE. When this box is checked, the falling edge will be detected; when it is not
checked, the transition will be ignored.
 Rising-edge: the indication of whether the service detects a rising edge. When
this box is checked, the rising edge will be detected; when it is not checked, the
transition will be ignored.
 Filter time: the minimum time lapse between two events. Permitted values range
from 0 to 65,535ms; the default value is 0ms.
 Reference Variable: the variable whose value is displayed for a rising-edge or
falling-edge event. The supported data types for this variable are BOOL, SINT,
DINT, REAL,USINT, INT, UNIT and UDINT as well as simple data type members
of structures and arrays of the supported types. Reference variables must be global
or have the same local scope as the variable configured for SOE.
