About Station Signals
The following signals are available to the MultiPurpose TestWare acquisition
processes.
Note
All time related signals (Time, Rollover Time, Running Time, and
Rollover Running Time) start from zero when you press the Run control
to start the test.

Time
Records the time reference signal derived from the controller’s internal clock
which increments continually.
Note
It is not practical to monitor the Time signal for some types of data
acquisition processes (for example, Peak/Valley).
Rollover Time
Records the time reference signal derived from the controller’s internal clock
which resets every hour. Like the Time signal, this signal is not practical to
monitor for some types of data acquisition processes.
Running Time
Records the accumulated time of the test program, which begins when you
press Run, and ends when the program stops automatically, or when you press
Hold or Stop. Pressing Run after pressing Stop or Hold causes this value to
resume incrementing.
Rollover Running Time
Similar to Rollover Time except it increments only while the station test state
is not in the stopped state.
Date
Time of Day
Date is an integer number of days since Jan 0, 1900. Time of Day is a fraction
of a day since midnight. Both signals are float values that can be imported into
Microsoft Excel, formatted as separate date and time columns, and added
together to form one date/time column. Both signal values correspond to time
stamps in the station log.
(Controller) System
Tick Count
Records the accumulated number of system ticks (updates) generated by the
controller (or multiple controllers in a multi-controller configuration) from the
time the Sysload application is started in the current session
System Tick Count is typically a large unitless integer. It can be used as a
reference if you acquire signals from other controllers. It can also be useful for
synchronizing acquired data for off-line plotting when using spreadsheet
applications, such as Microsoft Excel.
