Creating and Editing Tasks with the Task Manager

into Control Block tasks to simplify their creation. This file should not

be edited.
Note that when you edit a Control Block task or a UDC task, a

SCAN_LOOP statement and END statement (from the template) will

already be in the file when it is first opened. Both of these statements

are required for Control Block or UDC tasks to be compiled. The

parameters in the SCAN_LOOP statement must be filled in. BASIC

tasks will contain an END statement (from the template) when the

task file is first opened.
Refer to the instruction manuals for the BASIC, Control Block, and PC

programming languages for more information.

Compiling a Task

Use the Compile command to compile one or more selected tasks.

BASIC, UDC Control Block, and AutoMax Control Block tasks must

be compiled before being downloaded to the rack. PC/Ladder Logic

tasks and .INC tasks do not need to be compiled. The object code

generated is written to a file with the same filename as the source,

but with a file extension of .OBJ. If an object file with the same

filename already exists, it will be written over.
Step 1.

Select the task(s) you want to compile.

Step 2.

Select Compile from the Task menu. Each of the selected

files will be compiled.
AutoMax will create a log file (.LOG) for each task that is

being compiled. You can view a log file by selecting Edit

Any File from the Commands menu, and you can print it

by using the print command from the Windows File

Manager or from your text editor.

If an error is detected during compilation, no object file will be

created. All errors will be listed to the screen by line number and will

be written to the log file, if any. When the task has been compiled

successfully, the Obj Curr" column in the tasks display will contain a

checkmark (✓).

8.8

Verifying Tasks

Use the Verify command to check that all the variables defined in the

selected task(s) are used, that the configuration for the rack is valid,

and that no syntax errors are present in the selected task(s).
The Verify procedure will first compile the rack configuration file,

referred to as _CONF.CNF on the screen during the compilation

procedure. A log file will be created to store errors, as well as

compilation statistics. The log file is named _CONF.LOG. If there are

any errors, an object file will not be created. Refer to Appendix D for

configuration file size limits.
Note that the configuration log file errors will be displayed in the form

of statements with line numbers, which are used by the operating

system only. Ignore the line numbers and statement format. Use the

descriptive error message immediately underneath the line number

to determine the error. For example, the message symbol already

defined" will be displayed when a duplicate variable name is found in

the rack configuration and the offending variable will be clearly

marked on the screen. You can view a log file by using Edit Any File
