Storing Parameters TAC32

It’s my first time working on a TAC32 and I’ve see the fault log full of 1150 UP RUN STALLED faults. I checked out parameter Z44 which was set to 5 seconds, and changed it to 10. I logged off the IUT, and then reset the mainline to see if my parameter was stored. When I checked, the parameter had returned to 5 seconds. Is there a step I’m missing in storing this parameter?

WRT command

I apologize but I’m very new to this controller, can you elaborate?

EDIT: scratch that, I see what you mean now. I’m still trying to get the hang of this UIT.
