In my application ,the UR Robot is executing a script, which is sent through the **secondary port**.  
I want to write 6 float numbers to a register by the function **write\_output\_float\_register**.  
In order to ensure **not interrupte the ongoing script**.I tried to send script by RTDE port.  
here is the script.  
def writeOutputFloatRegister():  
write\_output\_float\_register(3, 1.1)  
write\_output\_float\_register(4, 2.2)  
write\_output\_float\_register(5, 3.3)  
write\_output\_float\_register(6, 4.4)  
write\_output\_float\_register(7, 5.5)  
end

I sent it with secondary port ,it worked, but RTDE was not.  
What should I do for this?
