4.3.2 Sensors for Temperature Measurement (°C)
4.3.2.1

Standard Data Format

For I/O module 750-498, the temperature values of the sensors are displayed at
a resolution of 1 digit per 0.1 °C in one word (16-bit). As a result, 0 °C
corresponds to the numeric value 0x0000 and 100 °C to the numeric value
0x03E8 (dec. 1000). The temperature underranges and overranges refer to
manufacturer range violations.
