Diagnostics and Troubleshooting

The Parser is an internal component of PowerTools Pro software that reads your program text file and generates executable

code used by the FM3 Module firmware. The parser detects errors that are reported to you as Red Dot Error Messages.

Program errors are displayed in the program view in Red Dot Error Messages. They are indicated with red dots. To get further

information on the cause of the error, use the program toolbar RedDot Help button. This is an on/off setting that enables error

message displays and application help messages.

Non-Programming Error Messages

These messages occur while you are working in a view other than the Program view. The Program view has error messages

specific to it, and they are described in a Programming Error Messages section. The popup messages are listed below.

Can Not Add Index, until current is valid.,

Can Not Add Jog, until current is valid.,

Can Not Add Program, until current is valid.

The current view must be valid before you can create a new instance of Index, Jog or Home.

Error: The maximum limit of Instances is reached.

The number of Index instances, Jog Instances and Home Instances is limited. If you attempt to add an instance and the

number of existing instances is at the maximum, you will get this message.

Programming Error Messages

These Red Dot Error messages occur while you are working in the Program view.

When creating a program, the parser is executed when you left mouse click, when you arrow off the current Line, when you

enter the carriage return, when you paste or when you drop a drag source. The parser detects errors and marks the line with

a “Red Dot”. To get further information on the cause of the error, use the program toolbar Red Dot Help button. This is an

on/off setting that enables error message displays and application help messages.

Problem/Message Cause Solution

Your Application is not valid to

download ...

There are errors such as “Red Dot” errors in one or

more programs that prevent the program from

being downloaded to the module.

The message will provide more information such as

which program is invalid to help the user correct the

problem.

Your Application has ...

There are errors such as “Red Dot” errors in one or

more programs. The operation (i.e. file save) was

completed, however other operations such as

download would fail for this application.

The message will provide more information such as

which program is invalid to help the user correct the

problem.

A FM-3/FM-4 number’s decimal

Point resolution can not be greater

than ten

The FM-3/FM-4 does not use standard floating

point. It uses Integer arithmetic to prevent round

off errors. Decimals are used, but decimal point

position is handled separately from the integer

value. Zero puts the decimal point to the far right.

Ten puts the decimal point at the far left.

The decimal point position must be between zero and ten.

A FM-3/FM-4 number’s mantissa

must be between -2147483647 and

2147483647

The mantissa must be between -2147483648 and

214748364.

The decimal point position must be between zero and ten.

A numeric variable can only be

assigned a numeric value

The Variable is a numeric. It only accepts types

consisting of numeric values.

A string variable can only be

assigned a quoted text string

The Variable is string. It only accepts types

consisting of text strings.

Can only compare(>,<,etc) numeric

results

This message occurs in conditional Expressions

(i.e. If then). Variables are type identified, so

equation and assignments (x = 9) can be verified.

In an expression only numerical values can be

compared for greater than and less than conditions.

Could not find the variable See message.

Could not find the variable defined

by program text

See message.

Destination Event variables can

only be assigned an Event or

Boolean

The Variable is an Input event. It only accepts

types consisting of Boolean, and events.

Program Instance does not Exist

You attempted the “Call Program.#”, but the

program does not exist.

Single value expressions can only

be Boolean constants, Events or

Boolean variables

This message occurs in conditional Expressions

(i.e. If then). Variables are type identified, so

equation and assignments .(x = 9) can be verified.

In an expression you can use single variables without a

comparison, but , then they must be a Boolean constants,

Events or Boolean variable.
