Internal Variables
Internal variables can be used and selected in the same way as different drivers. A
number of volatile and non-volatile user-defined variables can be selected. When a
value is changed, the non-volatile variables are saved in the flash memory to be read
at the next start-up. The system variables are fixed. These can be used to display e.g.
poll intervals and for toggle functions. By clicking Properties & Help in the I/O
Browser or selecting Functions /I/O Configuration/Internal Variables the following
window is displayed.
The system variables are used according to the tables below:
