5.5.5 How to enter the address in LAD
When you enter a command in the LAD, the instruction contains question marks.The
question mark indicates that the parameter is not assigned.You can assign values to
the parameters of the element when you enter the element.If the parameter is not
assigned, the program will not be properly compiled.
To specify a symbolic address, you must perform the following simple steps:
1.Enter a symbol or variable name in the address area of the instruction.
2. if it is a global symbol, the symbol table / global variable table is used for
Specifying a symbol name to the memory address.
Attention:you can use local variable table at the top of the program editor
window.Input symbol name in the "symbol" column.Because the compiler will
automatically specify the L memory address, you do not have to enter the address
for the local variable. You can drag the edge of the table to minimize the size of the
local variable table.
5.5.6 How to edit program elements in LAD
Cut, copy, paste, or delete multiple networks
By dragging the mouse or holding down the shift key with the mouse to select the
adjacent networks, you can choose a number of adjacent networks for cutting,
copying, pasting or deleting options.
First of all ,you should select a project, and then you can use the copy function.The
contents of the copy are placed in the Windows clipboard buffer.
You can choose the following objectives in the project:
1. Program text or data domain
2.Instructions in the LAD, FBD, and STL editors
3.
Single network
4.
Multiple adjacent networks
5.
All networks
6
.Symbol table, row and column of the symbol table
7.State table, row and column of the state table
