Setting AI835A Thermocouple
Hello,
I used the cards AI835A to measure a lots of temperature. (Thermocouple Type J)
The compensation takes place not via channel 8.
So I set the parameter of Cold junction compensation to "Fixed as parameter".
The documentation of the AI835A says that this is done by the application.
I get the temperature of the connection (PT100) also in the system and where can I connect this temperature in the application?
I use the Function Designer.

In Control Builder on the AI835A Hardware Unit, there are 8 Inputs and 1 Output QWxxx.9.
The Output Channel is where the Temperature must be connected that is used for all channels with Cold Junction Compensation Setting as "Remote cold jnc comp" or "From Application".
I don't know Function Designer but i guess your problem is that this 9th Output cannot be allocated there, you only get the 8 Inputs for I/O Allocation?
