ml1400 - monitoring the date?

PLC beginner here, so sorry if this is an obvious question.

I require my PLC to carry out certain tasks on particular days of the month (specifically to send out an email on 1st of every month. I am also reading up on how to send emails and that looks quite straightforward...)

Short of writing a load of logic to count seconds, turn that into hours, then days, and having a look-up table to keep track of what month and how many days etc.... Is there any way to simply record the date?

Thanks!

I think S:38 is the day of month. You could use EQU statetment comparing S:38 to the day of the month you want to use, which you said is 1.

So it is. Thank you!

S: files are for SLC family, Micrologix 1400 uses RTC.

Actually it does both, see pdf.

S:39 or RTC:0.DAY will give you the day of the month.

That's great, thank you

Hey Mickey, thanks !!
