Emerson FM-3 manual End, Formula

Programming

In the diagram below, => Represents a Call Program instruction

Program0=>Program1=>Program2=>Program3=>Program4 => NO MORE THAN 4!

Examples:

Call	Program.10	‘Program	10 contains a complex	home
		‘routine.
Call	Program.100	‘Program	100 contains a “teach	position”
		‘routine.

End

This program flow instruction is used to halt the execution of the program. It can be used in multiple places within the program. It is not required on the last line of every program. It is implied that after the controller executes the last line of code in a program the program will halt. It is commonly used inside of If/Then/Endif constructs to end the program if a certain condition has been met.

Examples:

If DriveInput.1=OFF Then

End

Endif

If DriveInput.1=ON Then

DriveOutput.1=ON

End

Endif

Formula

This program instruction can be used to enter a formula or assignment into a program. All FM-3 parameters are available for use in a formula. They may be dragged and dropped into a formula, but the program User Level will determine how many appear for dragging and dropping (see the section on User Level in the Setting Up Parameters chapter). Formulas can also be created by simply typing them into the program. This instruction was created to inform the user that formulas can be used in a program.

Examples:

Index.1.Vel = 20.0

Index.0.Dist = Index.2.Dist + 0.1

ModuleOutput.1 = ON

Index.0.Accel = (Index.0.Accel*1000)+5.00
