Section 7. Creating and Editing Datalogger Programs
Editing functions are available from the Input Location Editor’s Edit menu and
a hot key:
Insert (<F2>) – Inserts blank Input Locations. This is used to provide space for
new input labels between existing labels. This automatically changes the Input
Location numbers for all of the labels that are after the inserted location.
Delete (<F3>) – Deletes the Input Location label, flags, number of reads and
writes, and block information for a designated location number. Wherever the
datalogger program references a deleted location label, the Input Location’s
number automatically becomes 0.
Move (<F4>) – Moves the Input Location to a different number. This may
change several Input Location numbers.
Toggle Manual (<F5>) – Allows the programmer to manually toggle a location
as “in use”. This is used for burst mode, indexed loops, or other situations
where it’s not clear to Edlog that the locations are being written to. Input
Locations not marked as read, write, or manual are deleted by the Optimize
command.
Optimize (<F6>) – Deletes Input Locations that aren’t read, written to, or
marked as Manual. Optimize tries to reduce the total number of locations used
by moving existing Input Location labels to fill in unused locations. This
might change several Input Location numbers. Any changes in location
number made by the Optimize command are reflected in the Edlog program.
Insert Block (<F7>) – Inserts and labels a block of Input Locations and marks
them as “Manual”. The locations are labeled in the same manner as reps.
Esc – The escape key closes the Input Location Editor and updates the label
assignments in the program.
7.4.10 Input Location Anomalies
In most instances, Edlog will automatically assign Input Locations for
locations which are generated by the datalogger program. An example of this
is Edlog’s handling of Input Locations for the REPS parameter. Though only
one Input Location is specified, if REPS is greater than 1, additional Input
Locations are created by Edlog.
There are certain instructions that generate multiple Input Locations for which
Edlog does not automatically allocate Input Locations. The user should
manually allocate these locations in the Input Location Editor. These are:
• Instruction 15, Serial I/O with Control Port
• Instruction 23, Burst Measurement
• Instruction 49, Spatial Maximum
• Instruction 50, Spatial Minimum
• Instruction 54, Block Move
