5.24.2 Measuring Methods and Measuring Ranges of the SM 431;AI 8 16 Bit
Measuring Methods
You can set the following measuring methods for the input channels:
Voltage measurement
Current measurement
Temperature measurement
You specify the setting by means of the “Measuring Type” parameter in STEP 7.
Unused Channels
Disable the “Measuring Type” parameter for unused channels. In this way you
shorten the scan time of the module.
