hello i have form fill packing machine with the s7 224 plc and proface HMI.
all the time parameters are set in the HMI according to the packaging .
So far from the beginning when we stop the machine for a week all the time values in the hmi becomes 0000.
all time values are stored in v memory .
how to prevent this problem of not losing the v memory data.
because everytime we resrart the machine i have re enter all the values again almost 25 time values
