Getting Around in the AutoMax Executive and Windows

Each variable name must be defined as one of two types: local to the

task or common to all Processors in the rack. Local variables are

those that do not represent a physical I/O point and are not

referenced by any other application tasks running in the rack.

Common variables are those that represent physical I/O points or are

referenced by other tasks in the rack.
The PC editor will prompt you to enter L" for local or C" for

common. If you enter L", the variable will then be displayed in

lowerĆcase. If you enter C", the variable will be displayed in

uppercase. Inputs (contacts) are assumed to be common and

displayed in uppercase by the editor unless you have already

specified them as local earlier in the task. If you specify the variable

as local later in the task, the variable will be displayed in lowerĆcase

when you edit or view the initial sequence containing the variable.
Each variable name can have a 40Ćcharacter description which can

be printed out along with the sequences. However, the PC editor only

prompts you for a 40Ćcharacter description for coils. Descriptions for

other variables can be entered by using F3 A, described below. Only

the coil description will be displayed on the screen when you edit a

sequence. When you monitor PC tasks in the online mode (see 18.4),

however, the screen will display the description for any variable you

are monitoring.
The description is broken down into four groups of 10 characters.

The ^" characters indicate where the line will be broken up on the

printout of the task.

PC Editor File Commands

F3 is used to initiate a file command. F3 followed by one of the

following keys executes the indicated command.
E Ć

Exits the PC editor and saves updated file. If an existing file

was being edited, the old file will be renamed

FILENAME.~PC".

Q Ć

Quits the PC editor without saving. Any modifications to the

task are lost.

R Ć

Resequences a range of sequence numbers. This function

allows you to renumber a portion or an entire task. You will

be prompted for the first and last sequence number to be

resequenced (inclusive), the new first sequence number,

and the new increment.

M Ć

Moves a sequence or range of sequences to another part of

the task. You will be prompted for the first and last

sequence numbers to move and the new first sequence

number. If you are moving a set of sequences, they will be

numbered using an increment of 10 after the first sequence.

If an increment of 10 causes an overlap of sequence

numbers, the editor will attempt to increment by 1. If overlap

occurs, an error message is displayed.

S Ć

Substitutes a new/existing variable name for an existing

name. You will be prompted for a range of sequence

numbers to which the substitution will apply. The

substitution can be qualified to apply to certain element

types only by entering one of the following options:
