cFP-TC-120 Open Thermocouple Error increases software loop time

[Venkat]

Dear All,

I am using cFP-TC-120 with cFP-2020 field point controller. I am trying to read four thermocouple channels. To do this I am reading each channel using Read VI in a FOR loop which is taking long time ( one run 3ms and four runs more than 15ms). To reduce time I tried to use Read all option. But because four channels are not connected I am getting warning message (Code: 33448 ,Unconfigured, Bad Status "A", Bad Status "B". : FP Read.vi )and time for read operation is also too high(app 150ms). In this condition what I can do? I have only 3ms time to read all requied channels.

Thanks,
S.Venkatakrishna

Hi,

Please take a look at the shipping examples for FieldPoint. These can be found in Help>>Find Examples>>Hardware Input and Output>>FieldPoint>>Getting Started>>Analog Input.vi. Try this example, and see if it helps.

Have a Great Day!
