2-4 PC208W, Version 3.3 Instruction Manual
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
with PC208W. 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
