Press the WATCH LIST soft key to call the menu of the WATCH LIST function.

Press the SYMBOL LIST soft key to open a list box containing all global and

local operands used in the PLC program.

Use the arrow keys to move within the SYMBOL LIST. Press the right arrow

key to open a tree structure. Press the left arrow key to close an open tree

Use the arrow keys to select the desired operand and press the SELECT soft

key to transfer it.

Press the INSERT soft key to insert the selected operand.

Operands can only be selected with the SYMBOL LIST soft key if you are

working with the *.SRC source files of the PLC program on the control.

Otherwise the error message Selection list is empty appears.

Press the WATCH LIST soft key to call the menu of the WATCH LIST function.

Press the INSERT LINE soft key.

The following dialog box appears:

Enter the symbolic operand name in the Symbol input box, or enter the

module name in the Module input box. Press the GOTO key to view a history

list of the operand and module names last entered.

Confirm your entry with the OK soft key or button.

If you are working with the source files (*.SRC), the control internally creates

a complete symbol list from the *.MAP file, identifying the structures and

arrays. In another step, the control resolves the structure elements and array

elements, removes the nesting levels and internally creates a new list file. The

generated information is displayed in a tree structure (SYMBOL LIST

function). When you select and then insert symbols the first time, the file

PLC:\TABLE\TMP.WLT is automatically created. This file is automatically

saved when you exit the WATCH LIST function and loaded when you call the

WATCH LIST again. You can save the active WATCH LIST under any desired

name and then reload it. The control remembers the last active WATCH LIST

and automatically loads it when you call the function again.
