Note 1
Thermocouples (J, K, T, R, S, B, N) and RTD Pt100 (3-wire) Inputs
The process value is always measured in 0.1°C/°F resolution. That is, for example, the value 300 means 30.0°C / °F.
The same should be followed while setting the values for the parameters that are resolution based (like Zero Offset, Alarm Set-point, Alarm Hysteresis, etc.). That is for example, set 300 counts for 30.0°C / °F. DC mA / mV / V Inputs
(Also Refer Appendix A : DC Linear Signal Interface)
The measured PV is a Resolution-less Scaled Value derived using the values for the parameters : Signal Low, Signal High, Range Low and Range High. The parameter ‘DC Resolution’ holds the desired resolution that can be used to insert appropriate Decimal Place in the scaled PV. For example, if the DC Resolution value is 2 (0.01) then the scaled value of 3000 can be read as 30.00.
Similarly the corresponding parameters like Zero Offset, Alarm Set-point, Alarm Hysteresis, etc., are also resolution less and, if desired, the parameter value for ‘DC Resolution’ should be used for appropriate Decimal Place.
Note 2
Conditional Parameters are those whose usage depend upon the values set for some other parameters. For example; the parameters ‘Signal Low’ & ‘Signal High’ for a selected channel are used only if the input type for the selected channel is DC Input (mV / V / mA). The access to the conditional parameters for Read / Write operation, however, is not restricted.
