Utilities-Clock

[Mikel]

Hi Guys,

Hope you're all safe and doing well.

Is there a way to reset a memory float register to zero using the clock function under utilities.

I'm accumulating data from a flow meter into an MF register.

I need to reset the numbers in this register to zero at the end of every month.

How do i do that if its possible

Thanks

Mike.

You can store the date every couple seconds or minutes and compare the stored to rtc. If different hit reset your data.

If your PLC is on all the time, you can just compare SI 37, and when it equals 1, then it is the start of a new month. If the PLC is not on all the time, simply store SI 38 to a MI, then compare to SI38 on power up, and if different, reset your data.
