Configuring the input field
Use the cursor to select the first line of the first screen entry. Using the cursor control keys, position
the cursor behind the text Filling time. Activate the menu item Insert → Input/Output Field or press
the button in the function bar. The Input/Output field dialog box appears.
Set the Field Type : Input and specify a Field Length of 4. Do not change the settings Usage: Tag
or Display: Decimal.
To establish the link between the field and the PLC, create a new variable with the button
Give this variable the name Parcel by overwriting the preset variable name. Then make the
following entries: Type: WORD, address DB: 46, DBW: 0.
Click the OK button to close the Tag and Input/Output field dialog boxes. You have now defined the
input field. The variable is identified by {Parcel} in the Screen Editor.
Position the cursor between the text Max.number: and the input field {Parcel}. Now enter blanks
to make full use of the line. But make sure you do not exceed the maximum of 20 characters per line.
11 characters of text plus 4 characters of field length therefore mean a maximum of 5 blanks.
