4.1.4 Declaring The ISaGRAF Project Variables
Before you can start creating an ISaGRAF program, you must first declare the variables that will be used
in the ISaGRAF program.
Boolean Variable:
To begin this process, first click on the "Dictionary" icon and then click on the "Boolean" tab to declare
the
Boolean variables that will be used in our example program.
To declare the program variables for the ISaGRAF project, double click on the colored area below the
"Boolean" tab, and a "Boolean Variable" window will open. Enter in the name of the variable to be used
in the project. For the purpose of this example program the variable "Boolean Variable Name" is "K1",
and "Input 1 in the I-87055W board" is added to the "Comment Section". The next item that must be
declared is what type of "Attribute" the variable will possess. In this example program, K1’s attribute will
be an "Input". Then press the "Store" button to save it.
The new Boolean variable has now been declared.
NOTE: You MUST make sure that the variable you have declared has the desired Attribute assigned.
If you decide that you want to change a project variable’s attribute, just double click on the
variable name and you can reassign the attribute for the variable
Please follow the above same step to declare one another Boolean variable – “K2”. Then you will have
as below.
