2.2 GETTING STARTED
2.2.1 CREATING A NEW EDLOG PROGRAM
The steps for creating a new datalogger
program are:
1. Start EDLOG from PC208W by clicking on
the toolbar icon labeled PROGRAM.
2. Select FILE | NEW.
3. When prompted, select the datalogger type.
4. Develop and edit your datalogger program
(Sections 2.3 and 2.4).
5. Select FILE | SAVE to save and name the
program.
6. When prompted, select YES to compile the
program.
7. Exit EDLOG by selecting FILE | EXIT.
2.2.2 EDITING AN EXISTING PROGRAM
Instead of using FILE | NEW, load an existing
program by selecting FILE | OPEN.
2.2.3 DOCUMENTING A DLD FILE
FILE | DOCUMENT DLD FILE is for creating a
documented (.CSI) file from the instructions in a
.DLD file. This might be used if a program was
keyed directly into the datalogger (or modified
with the keyboard) and then retrieved in a
datalogger session. After creating a
documented file, make sure to save it using
FILE | SAVE.
Programs created with versions of EDLOG
earlier than 6.0 were stored with the instruction
description and comments in a *.DOC file and
the download code in the .DLD file. These
programs,
without the programmer’s comments,
can be imported into this version of EDLOG with
FILE | DOCUMENT DLD FILE. To convert
these programs and retain the programmer’s
comments, use DOC2CSI (Section 6).
2.2.4 THE PROGRAM DEVELOPMENT
TEMPLATE
When FILE | NEW is selected, the template
shown in Figure 2.2-1 appears in the
PROGRAM DEVELOPMENT screen. A
program consists of instructions, comments,
and expressions inserted into Program Tables 1
and 2 and the Subroutine Table 3.
The Table Headers and Execution Intervals are
protected text which cannot be deleted or
commented out. When the cursor is moved to
the Execution Interval line, the value for the
execution interval is highlighted. A numeric
value must be entered or the instructions in the
table will not be performed. On the blank lines
in each of the program tables, instructions can
