Automation System Accessing an Edition Field
The connected device sets a variable field into edition mode by writing its number in
a word in the dialog table. To display the number of variable fields in Vijeo-Designer
Lite, use the Layout → Display Fields Indices menu.
In return, the XBT terminal writes the number of the field being completed in a word
in the dialog table (see Exchanging Data with the Automation System via the Dialog
Table, page 151).
Specific feature of this type of selection:
You cannot select another variable field at the XBT terminal until the one requested
by the connected device has been completed because the MOD key is inactive
during this time.
5th time MOD is pressed: Edition field no. 1, etc.
Field no. 5 cannot be the edition field because it is not visible on the display unit.
