set oven mod

[krispiekream]

hi there. i was wondering if someone can help me.

i thought everything was working fine until i realized that once the temperature changed. it won't change the second time.

i am running a test. at 37 degree, at 42 degree, and at 35 degree.

i first set the temp to 37. once finished after 2 days. i auto set it to 42, 2 days later, to 35 degree.

i have a total of 4 systems. all of them only have 1 oven except 1 with 4 ovens.

all the 1 oven sys are working as planned.

but i am facing issue with this 4 oven system.

once the system set to 37, then it do its pressure cyclying. 

it will not set to 42 after due to ERROR..

then i restart program without restarting the computer.

it will NOT SET to 37 initially due to the same error.

but if i restart the computer. it set to 37 again.

i think i might be missing some step about closing the serial or something. 

can someone guide me through this.

Hi krispiekream,

nice description of what you want, but bad description of problems...

What kind of ERROR???

For your vi:

- when you do something 4 times: Use a FOR loop instead of a stacked sequence of 4 frames each containing the very same flat sequence of 5 frames!

- wire the error cluster directly to the case selector instead of unbundling the status bit (just try it!)

- why do you work with strings instead of numbers?

- left-to-right wiring? straight wires? Thank god, I'm using LV8.6 now with it's "Cleanup diagram" option

Just forgot:

- why do you move vi.lib functions to your local folder (General Error handler.vi)?

- why don't you use a subvi for the inner flat sequence - you need that piece of code more than once...

sorry. i was rushing when writing the piece of the code that would work for other ovens.

i just worked with what was given to me and i thought that it would be easier and quick just to duplicate it 4 times and then change the port setting. 

hmmm...i dont know what to say...now when i run it. i don't have that issue. this is one wierd problem.
