Custom software for TC-08 and Watlow controller

Postby arleyl » Thu Mar 15, 2007 10:04 pm

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.

Hi and thank you for your post.

We provide drivers and programming examples in various languages for the TC08. I would recommend to install the software and do a custom installation, you will find installed in the examples folder under your pico directory the code for the TC08 (USB and serial). The documentation also gives a description of the function calls, please have a look at the link below for the manual:


Hope this helps.

Kind regards
