Hello everybody,
I’m writing an application that communicates to a PLC via BR.AN.PVIServices.
There seems to be no way to find out whether a variable is declared constant (VAR_CONSTANT) other than actually trying to write it and getting an error message.
I’m connecting via the usual chain Service->CPU->Variable.
In the decompiled code of BR.AN.PVIServices there are some hints on const variables (VariableAttribute.Constant), but those parts of code are never called.
Any ideas are highly appreciated.
