DTOS + CONCAT help please

I'm writing a new program for a CompactLogix 5069-L310ER.

I used a GSV to grab the date and time from the processor. Then several DTOS and CONCATs to convert the DINTS into one string to display on my HMI, (event driven time stamp). That all worked just fine until this afternoon. When "14:00" should have been displayed, "14:0" was shown. My logic cut off one zero. How do I get my missing zero back? Minor issue, but it's bugging me.

Thanks
Justin

When I need to fill the string with 0's, I take the original DINT, add it to some order of magnitude larger, do the DTOS and the use MID or DELETE to take the part I want. For example add 100 to your minutes, do the DTOS and then drop the 1 off the front. The resulting string will be 'xx'. You can CONCAT that with your time to get your 14:xx.

Here's one I made which I adapted from the Rockwell one.

There is a routine in there to convert wallclock time to string.

Check out this thread. It also has a subroutine you can import.

It formats the Time as this: 01/14/2013 08:35:57

But if you have yours built just add a branch to CONCAT '0' if values are less than 10

Depending on your format this could include Month, Day, Hour, Minute and Seconds as shown above.

Good luck with your project!

Thank you, I got it working. I used the ADD and MID to make it work.

No worries. No point making it more complicated than it needs to be
