How do I clear String Register w/ MicroLogix 1400?

[FNC]

I am using string registers with a MicroLogix 1400 and need to clear some data.

The CLR (clear) command does not work. How do I do this?

I usually just have a NULL string labeled in the program and copy it into the string I want to clear. There may be a better way just never looked.

fill it with zeroes

This is the method I have always used. I not sure how you would use the CLR instruction on a string.

IF you want to clear your Read and Write buffer then you would use the ACL function.
