Since a compensation wire is used to connect the thermocouple to the control room, is it necessary to include the control room temperature in the DCS as well?

For example, if compensation wires are laid to the control room where the temperature is 25 degrees, does it need to be added as 25 degrees in the DCS? Thank you.
DCS systems generally have automatic compensation for the cold junction of thermocouples, so no additional measures are needed； If DCS is not available, it needs to be added....
A temperature-sensing thermistor should be placed near the I/O card channel of the DCS-connected thermocouple. There’s no need to add it to every channel and every card.
The DCS card’s thermocouple input features cold junction compensation. No need
The compensation wire itself is used to compensate for the temperature in the cabinet room within the measurement circuit; this is why it is necessary to maintain a constant temperature in the cabinet room. There is no need to manually enter temperature values during calculations
You are asking about automatic compensation, right? If the DCS has an automatic compensation circuit, then it’s not necessary
Isn’t there a temperature compensation function?
Who is right? Confused: lol
