I am using the RTC to start and stop some pumps. I enter a start and stop time from an HMI into an N7 integer register and compare the value to the RTC using the limit command. My problem is that the values entered into the N7 register don't stay when power is removed from the PLC.
Is there a different way to enter integers so that they remain when the power is turned off?
