4.3.11 FUNCTION (Cont.)
PV FORMAT
Numeric
Provides a decimal value for the maths channel.
Elapsed time
Shows the maths channel value in HH:MM:SS (hours minutes, seconds) format.
Normally used only for time functions. For other functions, elapsed time counts in
milliseconds e.g. a PV of 10000 would be displayed as 00:00:10; a PV of 60000 would
be displayed as 00:01:00
Scientifi c
Values are displayed and entered as a decimal number between 1.0 and 10† (the
mantissa), followed by a multiplier (the exponent). E.G. to enter a value of 1244.5678,
the value entered would be 1.2445678E3, where 3 represents the number of places
that the decimal point must be shifted to the left in order to convert the value to
a number between 1 and 10†. To enter a value of 0.0004196, the entry would be
4.196E-4.
Time/date
For timestamp functions, displays the timestamp as time or date as selected, instead
of a number of milliseconds, as would be displayed in numeric format.
† Notes
1. Strictly this is a number less than 10, as 10 would be 1.0E1.
2. There must be at least one number after the decimal point.
REMAINING CONFIGURATION ITEMS
The remaining confi guration items are identical with the relevant items in Input Channel confi guration
(

).
FUNCTION DETAILS
POLYNOMIAL FIT
A polynomial curve fi t of up to eight orders:
A0 + A1(X) + A2(X2) + A3(X3) + A4(X4) + A5(X5) + A6(X6) + A7(X7) + A8(X8) where X is the value of the
source channel and A0 to A8 are constants. Figure 4.11.3b shows the confi guration items for a third order
fi t with channel 2 used as the source (X), and A0 = 1, A1 = 2, A2 = 3 and A3 = 4.
