This special function module FX2N-4AD-TC
is used for processing temperatures. It has
4 independent inputs for detecting sig-
nals from thermocouples of types J and K.
The type of thermocouple can be chosen
independently for each point.
The electrical magnitude at an input is
converted into a digital numerical value
with a sign. The converted value is stored by
the PLC in a memory address, so-called
buffer memory, in the module and then
converted. It is also possible to calculate
a mean value from a predetermined
number of measurements in order to
obtain stable digital results.
The number of measurements must be
transferred by the PLC program to a
buffer memory of the special function
module. The value determined is avail-
able in another memory address.
