Grasp/Release KeyError


I have a robot where I recorded a very simple routine which I execute now!
From the executed T1_PICK I call different subroutines where I set the signal 200 true and false for grasp and release the part! → Why I get the following error? → The first time the robot grasp the part successfully by using the 200-signal in T1_PICK!


The problem is:

How to fix?

Thx & Regards
