4. Variable fields
In the case of a protocol other than XWAY, the accessible variables are singlel words, double words, floating words, and word bits.
The XBT-L1000 software makes it possible to define different field
properties. ( See chapter B, "Variable field characteristic", Page 29.
).
Accessing a field
Accessing the various fields in a page
The MOD key allows you to select: or
- The first field on the page
- The last field entered (the last field whose entry was confirmed by
ENTER).
The selected field is framed with a dotted box and the cursor is displayed in the variable field.
The arrow keys allow you to move from field to field.
When you are positioned in the desired field, press the MOD key to enable the input mode.
On touchscreen terminals, press the touch icon of the selected field for accessing the fields directly.
For the terminals with tactile keys, press the tactile keys for accessing the fields directly.

NOTE When configuring touch zones with XBT-L1000, the objects must be aligned on the XBT-L1000 default grid, otherwise the operator may be unable to select certain objects. If nothing has been entered after one (1) minute, the input mode is cancelled.
The order in which the page fields go to entry mode depends on the object alignment under XBT-L1000.

4. Variable fields
NOTE
Accessing a field by means of dynamic function keys, tactile zone or tactile keys
It is possible to select a field on a page by configuring a dynamic function key (Rx) associated with the page to select the field.
The same application procedures has access to an application page using the Rx key, with the action parameter : access to field.
Access to a field using the TXBT mouse
A field can be selected using the TXBT mouse by positioning the pointer on the field and clicking.
Request for entry on the initiative of the PLC
The PLC can request an entry in a page variable field (example: request for a set point).
The word “Field number to be entered” is reserved in the dialog table.
The program writes the number of the field to be entered in this word.
This number is provided by XBT-L1000, Display/Field number menu.
See chapter C, § %MWn+21: Recipe transfer not allowed, Page 25 , for
coding of this word.
Each field is automatically numbered by XBT-L1000. Numbering starts by number 1 for each page. The PLC program must thus check that the number of the page displayed is correct before requesting a field entry.
