Neither variable will be initialized:

{flag noinit on}

{flag noinit on}

Getting variables to the symbol file:

The flags „noread" and „nowrite" are used, in a POU that has read and/or write

permission, to provide selected variables with restricted access rights. The default for

the variable is the same as the setting for the POU in which the variable is declared. If

a variable has neither read nor write permission, it will not be exported into the

symbol file.

If the POU has read and write permission, then with the following pragmas variable a

can only be exported with write permission, while variable b can not be exported at

a : INT {flag noread};

b : INT {flag noread, nowrite};

{ flag noread on}

{ flag noread, nowrite on}
