28.04 Act val func Defines how the final process actual value is calculated from
the two sources selected by parameters 28.02 Act val 1 src
and 28.03 Act val 2 src.
Act1 The actual value is determined by parameter 28.01 Act val
1/2 sel.
0
Add Sum of actual value 1 and actual value 2. 1
Sub Actual value 2 subtracted from actual value 1. 2
Mul Actual value 1 multiplied by actual value 2. 3
Div Actual value 1 divided by actual value 2. 4
Max Greater of the two actual values used. 5
Min Smaller of the two actual values used. 6
Sqrt sub Square root of (actual value 1 – actual value 2). 7
Sqrt add Square root of actual value 1 + square root of actual value 2. 8
28.05 Act max val Actual value scaling. The setting equals 100% of process
setpoint and is typically set to the value that corresponds to
the top end of the sensor range.
0.00 … 32768.00% Actual value scaling. 100 = 1%
28.06 Act unit sel Defines the unit for both process actual value and process
setpoint. Typically the measured quantity is selected.
