Hello,

I am having some trouble with event routine. The routine itself is as follows:

MODULE user (SYSMODULE)

VAR wzstationary worldzone1;  
VAR wzstationary worldzone2;

VAR num testnum:=0;

PROC WZPos()  
VAR shapedata shape1;  
VAR shapedata shape2;

CONST pos corner1:=[455,200,650];  
CONST pos corner2:=[1050,-600,1100];  
CONST pos corner3:=[350,150,150];  
CONST pos corner4:=[1000,-150,600];

testnum:=5;

WZBoxDef \Inside,shape1,corner1,corner2;  
WZDOSet \stat,worldzone1 \Inside,shape1,doBusySlabi,0;  
WZBoxDef \Inside,shape2,corner3,corner4;  
WZDOSet \stat,worldzone2 \Inside,shape2,doBusyTrak,0;

ENDPROC  
ENDMODULE

The problem is that the routine WZPos doesn’t start. I think the worldzones are defined correctly, but the routine itself doesn’t execute. It is linked with a POWER\_ON event in controller configuration (see attachment) ![image.jpg](https://europe1.discourse-cdn.com/flex005/uploads/robotics1/original/2X/f/f0d61579fac9d9a0db12d4ede46f9732ed90d769.jpeg)  
.

Does someone know what could be the reason for this happening?

Thank you for all your help,  
Regards

Try to call the routine after boot up. See if you get an error more or less like “world zone already in use or activated”.

I tried and that is exactly what happens.

OK, so that tells us that it did run. You need to get motors on for the system to recognize the zones.
