793 Controller Signals Overview
The following signals are available to the acquisition processes for systems that run on the 793 platform.
Note:
All time related signals (Time, Rollover Time, Running Time, and Rollover Running Time) start from
zero when the procedure is started. They can be reset during the test using the Auto Offset activity.
Station Signals
Description Signal
Records the time reference signal derived from the controller’s internal
clock which increments continually. Time
Note:
It is not practical to monitor the Time signal for some types of data
acquisition processes (for example, Peak-Valley).
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. Rollover Time
Records the accumulated time of the test program, which begins when
you click Run, and ends when the program stops automatically, or when Running Time
you click Hold or Stop. Clicking Run after clicking Stop or Hold causes
this value to resume incrementing.
Similar to Rollover Time except it increments only while the station test
state is not in the stopped state. Rollover Running
Time
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 Date
Time of Day
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.
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. (Controller) System
Tick Count
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.
Records the binary state of the control, in which 1 = on, and 0 = off (in the
case of Run/Stop, 1 = Run and 0 = Stop). Interlock, Run/Stop,
Hold, Program
