3. Application pages
The application pages represent the basic dialog architecture and are used to:
- Monitor the control system
- Perform operations on the control system
- Maintain the control system
Structuring the pages
It is advisable to organize the application pages so that they reflect the various stages of the control process. The XBT-L1000 software allows you to do this.
Composition of the application pages
An application page consists of 3 parts:
- Application region,
- Status line,
- Alarm strip.

Note
The application region
It may contain the following :
- Static alphanumeric texts,
- Variable fields,
- Static graphic objects,
- Dynamic graphic objects,
- Dynamic function keys or touchscreen zone according to the terminal type,
- Optional alarm bar showing the last activated alarm.
Details concerning variable fields and dynamic graphic objects.
When creating an application with XBT-L1000, PLC variables are associated with the variable fields and the dynamic graphic objects.
For XBT-F
The accessible variables are single words, double words, floating words, word bits and ASCII strings.
For the MODBUS and MODBUS PLUS protocols, other types of variables are managed, see the service instruction related to the protocols.
A
For TXBT
In the case of XWAY protocols, the accessible variables are:
- Single words, double words, floating words, word bits,
- Local and remote input/output bit,
- double internal words,
- constant words,
- internal words
- internal words bit,
- internal bit,
- System bit,
- Step bit,
- Step macro bit,
- Step input step bit,
- Step macro output step bit,
In the case of a protocol other than XWAY, the accessible variables are single words, double words, floating words, and word bits.
