Lately we've received some questions about one of the key concerns in control: controlling something at a specific point in time.
- Maybe you want to turn on a pump at 6:00 a.m. every day
- Or start a process on Tuesday
- Or restart a count at midnight on the last day of each month
This tip pulls together some resources for control based on time, day, and date.

Do what when:
In last week’s blog we covered how to set the real time clock (RTC) in a PAC Controller with an accurate time server over the Internet using SNTP.Now that our controller knows exactly what time it is, how do we turn on that pump at 6:00 a.m. on the dot?
Like most aspects of programming, there are a few different ways to achieve the same result, so join me in this week’s blog while we look at one way to manage real-time scheduling.

What time is it?
Do you know what time it is? Does your SNAP PAC controller know what time it is? Are they the same time? Who’s right?

Of course you can include a trend in your PAC Display HMI or groov mobile operator interface and watch a value in your SNAP PAC System rise and fall over time. Or you can inspect a quick "plot" of it in PAC Control Pro's Debug mode.
But what if you just want to take a quick look at how high or how low an analog value has been, say, today?
This tip shows you how to do that using PAC Manager.
