Hello, i have a problem . I am working with CPU 1212C DC/DC/DC , order number 6ES7 212-1AE40-0XB0. I want to safe data from one analog input for some period, example one month , in PLC memory. My idea is to read value from analog input every hour, when CPU is working and save it to some data base. Is it good idea ? Maybe i can create some array and save information in it ?
Maybe convert data in integer to safe memory ?

Thank you!
