Dear all,
IN S7200 for timers i am referring the preset values through word like VW500,VW504 etc.
In case the memory of PLC is erased the values stored in that coressponding VW areas also got erased.
My question is if we use a constant value to refer the same is there a possibilty for it to get erased?
Are there any ways to prevent the data erasing problem?
Kindly help me in this regard
