4. Variable fields
Ex.
See chapter D, § 12. Variables adjustment on the TXBT, Page 68 .
Variable fields are zones enabling:
- the display of values reflecting the control system status: status of a word bit, single or double word, floating word, character string, or,
- the entry of parameters allowing the control system to be controlled: modification of word bits, single, double or floating words, character string.
The display format may be binary, decimal, hexadecimal, numbered list, or an ASCII character string.
Temperature = Field
When creating the application with XBT-L1000, controller variables are associated with the variable fields and the dynamic graphic objects.
For the XBT-Fs
Whatever the protocol, the accessible variables are single words, double words, floating words, and word bits. For the MODBUS and MODBUS
PLUS protocols, other types of variables are also available, see the protocols service instruction.
For the TXBTs
In the case of XWAY protocols, the accessible variables are:
- internal word,
- constant word,
- internal word bit,
- double internal word,
- internal bit,
- single words, double words, floating words, word bits,
- local and remote input/output bit,
- system bit,
- step bit,
- step macro bit,
- step macro input step bit,
- step macro output step bit.
