Measuring Methods
You can set the following measuring methods for the input channels:
•
Voltage measurement
•
Current measurement
•
Resistance test
•
Temperature measurement
You specify the setting by means of the measuring range modules on the module
and the “Measuring Type” parameter in STEP 7.
Circuit Variants for the Channels
Two channels are set in each case with the measuring range module. There are
therefore restrictions as regards the measuring method for the adjacent channels
0/1, 2/3, 4/5, 6/7, 8/9, 10/11, 12/13 and 14/15, as shown in the following table:
