12.2 Transient program files (.tls)
These files have the default file extension "tls" which is short for Transient
List. Transient list files contain the data that is entered by the user in the
transient screen. The user can create as many 'tls' files as needed but only
one can be loaded at a time. The LSGUI may also create a transient list file
with the extension "tld" which is short for Transient List Default. The name of
this file is always "lsgui.tld". This file is loaded automatically any time the
transient list screen is opened. If the 'lsgui.tld' file does not exist, an empty
transient list screen will be displayed. Other than its specific use, the
'lsgui.tld' file has the same format as a regular 'tls' file.
A transient list file is an ASCII comma separated value format file which
always consists of 16 records with 8 fields each. Each record corresponds to
a register in the L-Series controller, thus record 0 contains the data for
register 0, record 1 that for register 1 etc. The following fields are present in
each record:
Field Type

Transient list files may be edited using any text editor as long as the
edited files maintain the data structure outlined above. If values are entered
that fall outside available limits, an error will be generated when an attempt is
made to download the data to the power source. As a rule, it is
recommended to use only the LSGUI program itself to edit transient list files.
