Change P in running PID

$

Hi all,

I need to change the gain in a PID instruction while pid is running. I can't just write new gain in KP variable (it will be too easy), it make a hudge bump in CV..not really what we need (see picture). Rockwell suggest to put pid in manual (.SWM) then change the gain and put back to auto. It's work but not fast enought, it's look like pid take time to calculated few thing on manual to auto transition. I'm sure there's a way to do this, I can't be the first who need to do that.

Thanks for help
