SIMATIC S7 Ex Analog Modules Temperature range type B 3-20 Table 3-19 shows the representation of the digitized measured value for the temperature range, sensor type B. Table 3-19 Representation of the digitized measured value of an analog input module (temperature range, type B) Temperature range in C type B Decimal Hexadecimal Range > 2070.0 32767 7FFFH Overflow 2070.0 : 1820.1 1820.0 : : 200.0 1) : 0.0 -0.1 : -150.0 20700 : 18201 18200 : : 2000 : 0 -1 : -1500 50DCH : 4719H 4718H : : 7D0H : 0H FFFFH : FF24H Overrange 2) Rated range Underrange 2) < -150.0 -32768 8000H Underflow In the case of incorrect wiring (e.g. polarity reversal, open inputs) or a sensor fault in the negative range (e.g. incorrect type of thermocouple), on dropping below FA24H the analog input module signals underflow and outputs 8000H. 1) The module linearizes the range from +1820 to -200C for type B. Below -200C, the rise of the characteristic curve decreases to such an extent that, from this point, precision evaluation is no longer possible. The rise in the characteristic curve at this point is retained until underrange is reached. The characteristic curve of the thermocouple does not feature monotone characteristics in the temperature range between 0 and 40 C. Measured values from this range are not distinctly allocated to a specific temperature. 2) The characteristic of the thermocouple is not defined in the overrange and underrange. The rise of the characteristic curve is retained on leaving the linearized range. It is not possible to specify the accuracy of these ranges.
