On-Line Constant Changes

LogicPro allows you to change all of the constants assigned to

a program while monitoring it in either Execution or

Simulation modes. All constants assigned to a Ladder

diagram Function Block’s input may be modified.

To modify a constant assigned to a Function Block's input:

1. Double-click the Function Block on the monitoring win-

dow. The On-Line Function Block Variables

Change dialog opens, as shown in Figure 15.7 on page

247.

I/O Address

Input/Output address of the variable.

In Variable Watch, the variable I/O

address contains the following

elements:

• Type of variable:

• I for input

• Q for output

• Size:

X for bit

B for byte

W for word

• IO Physical Address

• Driver name

For example, an I/O address in Variable

Watch could be:

IQ.X.0.0.2:Processor_2010.

Comments

Any comments that you attached to the

variable when you created or last

edited it.

Initial

The initial value that you gave the vari-

able when you created or last edited it.

Retained

Indicates whether the variable retains

the current value when the program

stops running.

If the cell is blank, the variable retains

the current value when the program

stops running and applies that value

when the program starts again.

If NO is shown in the cell, the variable

resets to the initial value when the pro-

gram starts again.
