SIMATIC S7 Ex Analog Modules Voltage measuring ranges 3-4 With these options you must first ensure by way of interrogation that you will not change the coding for invalid measured values (-32768 / 8000H and 32767 / 7FFFH) or you incorporate it in the filtering process. Table 3-3 shows the representation of the digitized measured value for the voltage measuring ranges 25 mV, 50 mV, 80 mV, 250 mV, 500 mV and 1 V.
