Ni100 (acc. DIN 43760)

With the setting "Ni100 (acc. DIN 43760)", the I/O module converts the resistance
measured values of Ni100 sensors (acc. DIN 43760) and outputs them as
temperature values.
The temperature values are displayed at a resolution of 1 digit per 0.1 °C in one
word (16-bit). Temperature values below 0 °C are represented in two's
complement binary. As a result, 0 °C corresponds to the numeric value 0x0000
and 100 °C to the numeric value 0x03E8 (dec. 1000).
The possible numeric range corresponds to the defined temperature range of
−60 °C ... +300 °C for Ni100 sensors (acc. DIN 43760).
