REXYGEN supports the permanent storage of function block parameters (e.g. as the ycn parameter of the CNR block). Parameter values can therefore be stored in persistent memory and this value will appear in the program after a power failure. For some specific blocks such as INTE, it is even possible to store the value of their internal state.
In order to store the function block parameters, the checkbox Persistent parameters in block properties must be checked. All function block parameters and also internal states in selected blocks will be stored (excluding arrays).
The full documentation to persistent memory is here: doc
