Resetting Intergers

[mmeeks 0]

Hi all.  I am in need of a little help here.   I am doing some stats that i put into intergers.  3 times a day i reset about 45 intergers and 40 floats all at the same time.   They are N21:0-N21:45 and F22:0-F:40.   The same bit resets all these.  Is there a way i can put this all in 1 line instead of adding 45 branches.  Any help would be highly appreciated as this is hurting my scan time now.  

 

Thanks

Not sure how much it will help your scan time, or exactly what processor you're using, but look at the FLL instruction:

If your processor doesn't have FLL, use COP. It works similarly, but you'll have to use an address for the Source that's always zero. Or, use a MOV instruction to put a 0 in the first register and then a COP to copy that value through the rest of the array:

Check out the online instruction help for FLL, COP, and MOV to get familiar with them.

Joe,  

Thanks so much for the help there.  That helped clean up the program alot.  I was searching for ways to do that for awhile and couldnt come up with anything.  I am using a Micrologix1400 series B.   The scan time was at 210 now im at 133.   I am doing stats of how that has 5 numbers that i track every hour.  What i found is if i only look at these lines when its that time this will help the scan time tremendous.  As right now its doing about 150 lines of math every scan.  This will go down to about 20 or 30 a scan.  Thanks for the Help much appreciated.

FLL always works best when you're clearing an array. I'm a big fan of the CLR instruction when zero-ing a single word of data.
