Accessing an Alphanumeric Edition Field
Overview
Alphanumeric edition fields can either be accessed by the user or by the automation
system.
User Selecting an Edition Field
To access an alphanumeric edition field, it must first of all be visible on the display
unit. To select the field, press the MOD key of the XBT terminal.
If there are several edition fields available on the actually displayed panel, press the
MOD key several times in succession to run through the variable fields in edition
mode from left to right and from top to bottom.
You access an alphanumeric edition field on XBT RT terminals in touch variant
directly by touching the screen if an active area has been configured by the HMI
application designer.
Example
Selecting an edition field out of several edition fields on the same panel:
1st time MOD is pressed: If no edition has been made in any field on the display
unit since the panel was displayed, the top left-hand
field on the display unit is the edition field (field no. 1)
Otherwise the edition field will be the one that has
already been edited (field no. 1, 2, 3 or 4).
We will assume that field no. 1 is the edition field
2nd time MOD is pressed: Edition field no. 2
3rd time MOD is pressed: Edition field no. 3
4th time MOD is pressed: Edition field no. 4
