Analog value representation (analog input modules)
All numerical values from 800
hex
to FFF
hex
represent negative values when coded as two’s comple-
ment. This is also relevant for binary numbers in which the most significant bit (bit 12) is "1".
The conversion into a decimal number is shown in the following:
→ Example of the conversion of negative numerical value, page 15-10.
The temperature and voltage values can now be calculated according to the parameterization.
For the parameterization
 "Type K, -270 … 1370 °C"
 "Type B, +100 … 1820 °C"
 "Type E, -270 … 1000 °C"
 "Type J, -210 … 1200 °C"
 "Type N, -270 … 1300 °C"
 "Type R, -50 … 1760 °C"
 "Type S, -50 … 1540 °C"
 "Type T, -270 … 400 °C"
use the equation:
temperature value = 1 °C × decimal value
The value range:
-270 °C to 1820 °C
is displayed as follows:
EF2
hex
to 71C
hex
(decimal: -270 to 1820)
 For the parameterization "+/50mV":
voltage value = 0,02443 mV x decimal value
 For the parameterization "±100mV":
voltage value = 0,048853 mV x decimal value
 For the parameterization "±500mV":
voltage value = 0,24430 mV x decimal value
 For the parameterization "±1000mV":
voltage value = 0,488530 mV x decimal value
The value range:
-50 mV to -0,024mV;
-100 mV to -0,049mV;
-500 mV to -0,244mV;
-1000 mV to -0,489mV;
is displayed as follows:
800
hex
to FFF
hex
(decimal: -2048 to -1)
The value range:
