Storage Tab
Storage Tab
Basic Description
Data storage is activated by trigger events. If any one event is triggered, data from all channels is stored.
Data storage events are triggered when a change occurs within the range of your defined parameters. An
example follows the parameter definitions.
Note: For Static Input Channel types (selected in the Input Channels “Type” column)
eZ-TOMAS calculates and stores the averaged value in the time block.
Panel Description
History FIFO
Displays the number of storage records in the History FIFO (First-In-First-Out) file.
Based on the configuration, values for both the required and the available disk space
are shown. The panel includes a checkbox to enable backing up the project. If the
project backup feature is enabled, the backup files will be stored in your EZ-TOMAS
project folder. They will have the same file name, followed by an underscore and a
number; for example, the first backup of a file called: TurbGen.tom would be
TurbGen_1.tom.
RPM Range The speed range in which data storage is permitted.
RPM Change An RPM-based trigger for the storage of data. Data will be stored when the machine
speed changes by the specified RPM value. To enable the delta RPM storage trigger
check the “Enabled” checkbox and enter an RPM value.
Time Change A time-based trigger for the storage of data. Enter the number of seconds, minutes,
hours, or days between desired storage events. To enable the time-based trigger
check the “Enabled” checkbox.
Overall Change An amplitude-based trigger that can be defined for each channel. Data is stored when
the overall amplitude changes by the specified value. The user must check the
“Enabled” box for each channel that is to be used as an overall change trigger.
