Instructions on commissioning

4.4.1 Processing the input signals of temperature sensors

Temperature sensors
Parametrizing
4−14
The analogue values are transmitted to the control system by
the CPX terminal as input words (4 inputs, 64 bits or 2 inputs,
32 bits). Each temperature module occupies 2 or 4 input
words in the address range for this procedure.
The position of the input words in the address range depends
on the field bus used (see manual for the field bus node).
Pt temperature sensors can be operated in two temperature
ranges:
Standard (− 200 ... + 850 °C)
Climate (− 120 ... + 130 °C)
Ni temperature sensors always operate in the temperature
range − 60 ... + 180 °C.
By means of parametrizing, the CPX temperature module
can be set to different temperature sensors and sensor con
nection methods.
In addition, the unit of measurement, the diagnostic reaction,
limit value monitoring, etc. can be adapted by means of
parametrizing. Instructions on this can be found in the sec
tions 4.4.2 and 4.4.3.
