Unit register +0 = unit
HART state register +0 = state 0
+1 = state 1
Command 2
Purpose Read primary variable current and percentage of span
Send register Not used
Return register +0, 1 = P. V. current mA (float point)
+2, 3 = P. V. percentage (float point) Purpose
Unit register Not used
HART state register +0 = state 0
+1 = state 1
Command 3
Purpose Read dynamic variables and primary variable current
Send register Not used
Return register +0, 1 = Primary Variable current (float point)
+2, 3 = Primary Variable value (float point)
+4, 5 = Secondary Variable value (float point)
+6, 7 = Tertiary Variable value (float point)
+8, 9 = Fourth Variable value (float point)
Unit register +0 = Primary Variable unit code, 8-bit unsigned integer
+1 = Secondary Variable unit code, 8-bit unsigned integer
+2 = Tertiary Variable unit code, 8-bit unsigned integer
+3 = Fourth Variable Unit code, 8-bit unsigned integer
HART state register +0 = state 0
+1 = state 1
Note Not all equipment return primary, secondary, tertiary and fourth
variables. If the equipment does not support them, zero is written
into the value and units unit code for that variable.
Command 15
Purpose Read Transmitter Variables
Send register Not used
Return register +0 = alarmselect code
+1 = transfer function code, 8-bit unsigned integer
+2 = P. V. range units code, 8-bit unsigned integer
+3, 4 = upper range value (float point)
+5, 6 = lower range value (float point)
+7, 8 = damping value (second) (float point)
+10 = private-label distributor code, 8-bit unsigned integer
