number in that range. If there a sequence number in

that range, the sequence number will be increased by

one. If that is not possible, the system will display an

error message.

The PC editor screen is a matrix of six rows by ten columns

representing the space available for creating one sequence. The

available sequence elements and file commands are displayed on

the command line of the PC Editor screen. See figure 4.11 for a

sample PC editor screen.

The PC editor functions and keystrokes required are described

below. When two keys are shown separated with a slash, e.g., Alt/F2,

they are to be typed simultaneously.
When you are creating a new Ladder Logic task, you will be

prompted for the initial sequence number. After the first sequence,

the editor will increment by 10 each time you press <PgDn>. When

you edit an existing Ladder Logic task, pressing <PgDn> displays

the next sequence in the task.
The PC editor opens a journal" file of all keystrokes you entered for

the current editing session. When you exit or quit the editor normally,

the file is deleted. If, however, power to the personal computer is

accidentally turned off, the journal file is saved and the user

prompted the next time the PC editor is called up.

PC Editor Variable Names and Types

In AutoMax ladder logic, variable names are used in place of physical

addresses. They are limited to 14 alphanumeric characters, and must

begin with a letter. The editor automatically reserves two lines of

seven characters each for each element. Typing the underscore _"

on the first line inserts an underscore and moves the cursor to the

second line, allowing you to divide the variable name into

recognizable segments.
