I would like to see how complex it would be to write a piece of software that will work on my application:
Application: Temperature testing of UUT (Unit under test) (embedded computing electronics) (-45C -> 85C cycles).
Temp Chamber: Test Equity 115
Temperature Controller (integrated with the 115): Watlow F4
Data Logger: Pico TC-08
What I would like to do is adjust the temperature on the Watlow controller based on what the computer is reading from the TC-08 . The controller is programmable (via serial interface) with sostware that uses Modbus RTU protocol. It comes with preprogrammed settings, but I always have to adjust the temperature since heat is dissipated by the UUT after power is applied. The key is to keep the UUT close to a certain temperature while it is operating. My view is to have the software adjust the temperature on the controller if the temperature it's reading from the TC-08 falls out of its range. Then setting at that temperature as longs as the temp reading from the TC-08 is within range.
Any comments or suggestions on how to get this started would be appreciated.
