PID control of heating element feedback timeout error

[becidea]

I have a problem about feedback and PID control. I am having timeout error.

Lakeshore 336 temperature controller

K182 nanovoltmeter

2 K type thermocouples

2 25ohms heaters

In my vi, there are two heaters control. Output's 1 is controlling the heater output 1, and Output's 2 is controlling the heater output 2. Both heater start heating, I guess they can start heating in order, 1sec differense for example, but reading should be simultaneously. Timeout error I am having attached.

I am not good at Labview, but i need to write this software. So, I am attaching my vi.

heaters will go to specific temp. and then measurement will be done, then the heaters will go to next set point as can be seen in vi I attached.

thanks in advance....
