In MP_pt100Discrete you define whether the values of the Pt 100 inputs are
transferred immediately or with a change rate of 1 K/s. The disadvantage of
transfer with a change rate of 1 K/s is that at high change rates it may take
some time until the correct temperature has been transferred. For example, it
would take 30 seconds to correctly read a temperature change of 30 K. An
advantage of this, however, is a low sensitivity to disturbance: the
temperature display will not jump back and forth between two values:
If you wish to transfer the values of the Pt 100 inputs immediately, set
MP_pt100Discrete =True
If you wish to work with a change rate of 1 K/s, set
MP_pt100Discrete = False.
