Control/CompactLogix Day of the Week

[pcmccartney1 141]

Any idea how to obtain or calculate the Day of the Week from WorldClockTime or any other attribute?

There is a KB about a specific instruction GDW for SoftLogix 5 only.

Hi, I can send you L5X file for an "Add-On Instructions" to add if you need. 

Once you add the L5X file and download the program, you can calculate the "day of the week". 

1. Make an 7 array of dint, for my example I have "WallClockTime"

This is to get current date & time

2. Make a tag with data type with DayOfweek_LD, for my example, I have "DayOfWeek"

This is where you can get the number of week.

0 = Sunday

1 = Mon

2 = Tues

3 = Wed

4 = Thurs

5 = Fri

6 = Sat

3. 

I hope this helps you out but if it does not make sense, please let me know. Thanks !

@PaulKim1003 Wanted to get back to you and thank you.  It worked quite well for me.  My associate built his own but studied yours and found them to be quite similar.  There are many formulas on the web that describe how to get day of week.
