Programming

Program Where Am I?

Clicking on this button will show the line of the program that is currently being executed. A blue arrow will point to

the line in the program that was executing when the button was clicked. The arrow will not continue to follow

program flow. If the program is not currently running, then the arrow will point to the top of the program, or to the last line

of the program that was processed before it was stopped. Only available while online.

Stop All

This button is the same as the Stop destination found in the Assignments view. Clicking on this button will stop all

programs and motion. If in motion, the motor will decelerate to a stop using the StopDeceleration ramp value. Only

available while online.

Disable Error Check

This button can be used to temporarily disable the program parser. The parser is what detects errors in a user program.

When user programs are very large, the parser can take an appreciable amount of time to check the entire program

for errors. To avoid this, the user can disable the program parser, enter all of the changes, and then re-enable the parser to

check for errors.

Global Where Am I Check Box

This parameter is used to control the functionality of the Global Where Am I arrow in a program. If the user activates the

Global Where Am I feature by clicking the Global Where Am I button on the PowerTools Pro toolbar, a blue arrow will

follow the program flow on a given task by pointing to the line of the user program that is currently being processed. If the

Global Where Am I is active, and one user program calls another user program (using the Call Program instruction), the

PowerTools Pro view will automatically switch to the “called program”. In some cases it may be desirable to stop the screen

from automatically changing to the “called program”, this can be done by disabling (clearing) the Global Where Am I Enable

check box. When clear, the Global Where Am I feature will not function within the specific program. Each program has its

own Global Where Am I Enable check box. By default, all Global Where Am I Enable check boxes are selected (active).

Programs

Motion Programs are a series of indexes, homes and jogs that have been previously setup. You combine these with other

programming steps to create a complex motion profile. Each motion program provides a series of movements in conjunction

with other machine functions. The movements are used to perform a particular machine operation.

Multiple programs can be created using PowerTools Pro software and stored in the FM-3/4 or Epsilon EP-P drive. The device

is capable of storing up to 55 indexes, 99 motion programs, and a maximum of 1024 program steps in Flash Memory. The

amount of available Flash Memory determines how many programs, program steps, indexes, etc. that the configuration can

hold.

The number of available programs and average number of steps per program are directly related to each other. The memory

is setup such that if you require 99 programs (maximum), each program can have an average of 10 program steps each. If the

number of programs is reduced to a minimum, you could have as many as 1024 steps in a single program.

Program Instruction Types

Program Flow Instructions

If/Then/Endif

This is a program flow control instruction used to selectively run a section of code only if a logical test condition is true. If

the test evaluates to true the code between the If/Then and Endif lines is executed. If the test evaluates to false the code is

not executed and the program skips to the next line of code after the Endif.

Logical tests (AND, OR, NOT) can be used in the If/Then/Endif instruction. Parenthesis “()” can be used to group the logical

tests.

Examples:

If DriveInput.1=ON Then ’Turn Outputs 1 On and 2 Off if Drive

’Input.1 is ON.

DriveOutput.1=ON

DriveOutput.2=OFF

Endif

If (DriveInput.1=ON AND DriveInput.2=OFF) Then

‘Turn Outputs 1 On and 2 Off if Drive

1 2 ... 110 111 112 113 114 115 116 117 118 119 120 ... 239 240
