Table 13: Analog Input Characteristics - Current
Note:
Input ranges: : When configured as 4 to 20 mA, input signals lower than 4 mA will result in negative values (-7,500 for 0
mA). In MasterTool IEC XE, there is a parameter called Open Loop Value was included to select the behavior in this situation.
The default value is Disabled (which provides a linear reading as described above), having also the option to provide a fixed
reading equal to lower and upper limits ("0" or "30000").
