14.1.11 Labware Attributes and String Variables
The Set Variable command allows you to read from and write to the labware
attribute “ID” from within pipetting scripts during script runtime. Freedom
EVOware uses the attribute “ID” to store the labware barcode. You can use this
feature to access scanned barcodes from within pipetting scripts.
You cannot read from or write to carrier attributes or other labware attributes in
this way.
This feature is available for both Freedom EVOware Standard and Freedom
EVOware Plus and is mainly intended for advanced applications. Take care when
modifying labware attributes.
In Freedom EVOware Plus, labware attributes are automatically assigned to string
variables, so it is not necessary to use the Set Variable command in this case (see
14.1.11.1 “Labware Attributes and String Variables in Freedom EVOware Plus”,
14-18).
Each of the attributes is associated with a script variable using the following
syntax:
$[index].$
[index] is the well number (for microplates) or tube number (for tube racks).
