Time Stamp:
When Time Stamp in Trend mode, the time, date, and day of each scan is stored as well as the scanned data
Range: On, Off.
Notes: Trend Logs: the user has the choice to deactivate Time Stamp, except when the data is not protected. If
the Time Stamp is deactivated, only the first record will be time stamped and the Program Loader Monitor will
automatically calculate the time in reference to the first time-stamp and the scan rate.
Event and Fault Logs: Time Stamp is activated by default. The user can’t change this option.
Alarm:
This output is usually wired to an LED or similar device. When the Memory bucket is filled up to a determined
percentage (see Alarm Percentage), the LED will start blinking as an alarm that the set point has been reached.
The LED will stay on once 100% is reached.
Range: On, Off.
Alarm Percentage:
When Alarm is ON, Alarm Percentage determines at which point (percentage) during the scanning of data to
allocation block memory the Alarm will start blinking. It can be used in the Bubble logic code to control other
logic sequences.
Range: 50%, 60%, 70%, 80%, 90%, 95%, 98%, and 100%.
Scan Rate:
The Scan Rate determines how often a variable will be logged in a Trend Log.
Range: 100ms – 108s
Note: Scan Rate does not apply to Event or Fault Logs.
Number of Variables:
The Number of Variables is used for tracking the Variables
within a Trend Log. For Event and Fault logs, this parameter
is only used by the Programming Tool.
Range: Trend 1 – 10 Variables
Event or Fault 1 – 5 Variables
Variable Names:
Enumerates the Bubble logic variable name to be logged
Range: 16 Alpha/Numeric characters only with no spaces.
Scaling Factors (Trend mode only):
Used by the Loader Monitor to convert integer data into
meaningful units of measurement (i.e. Floating Point – 2.5 V,
etc)
Range: None, 1:1, -1 Volt to 1 Volt, 0 Volts to 5 Volts, 0 Volts
to 10 Volts, 4 ma to 20 ma, Supply V, True / False, On / Off, 0.1, 0.01 (s), 0.001.
Note: The application programmer must set up Scaling Factors for Event and Fault logs in the code.
Message Editor Screen
The Message Editor is used when downloading Event or Fault data. The user defines error messages using
this editor, and then codes the conditions for trapping, logging, and displaying the errors in the Bubble logic. If
an Event or Error condition is met, the corresponding message number is also stored in the DVC70. When the
user downloads the data from the DVC70, the message number is compared to message numbers saved in a
text file. The actual message then gets written to the Loader Monitor output (.CSV file).
