can't get temp updates from FP_TC_120.vi

[Sloppy]

I'm trying to use the FP_TC_120.vi example but I am unable to get it to update the temp. It only reads the temp the first time through the loop. Subsequent times through the loop there are no read errors, but the temperature never changes. Only if I Stop the program with the Stop button and then restart it do I get an update of the temperature reading, but then it never changes again until I once again, Stop the program with the programs Stop button and then re-run it again


i know the temperature is changing. I am monitoring an oven and can see the temperature changing with other thermocouples.

I've tried using FP_Read as well as FP_Advise, the both act the same as descriped above.


Thanks in advance for any response

What network module are you using? If you have an ethernet network module (FP-1600, FP-2000, or FP-2010) and have configured deadbands on the channels, you may not be receiving updates because the channels are not changing outside of the deadband range. For example, if you have a channel configured for Celsius readings and a 10% deadband, the smallest detectable change is 0.10 * (270 +1770) = 204 degrees Centigrate. Even a 1% deadband still requires a change of 20.4 degrees to register and update your program.

To find out what deadband is configured with FieldPoint Explorer, right click on the FP-TC-120 and choose Edit This Device. Then choose Channel Configuration, the Percent Deadband setting is in the middle right side of the window.
