PID
Calibration process: By applying 20mA to the
-10.0 – 10.0% external actual value input, this parameter is
corrected until the readout matches 20 mA
-32768 - Mantissa of the real process variable (begin of
+32767 external actual value)
-32768 - Mantissa of the real process variable (end of external
+32767 actual value)
Position of the comma for process begin/end
-3 - 3 (P14.14, P14.15), e.g.: mantissa = 200, comma shift
= -2/2, process value = 2.00/20000
--
Unit of the real process variable
0.1 - 10.0% Tolerance range for the control deviation (set point –
{1.0%} external actual value) where no adjustment occurs.
