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.
