6) Moving average
Entering method of the formula
AVE (X#T)
AVEH (X#T)
X: Data channel number, T: Time series interval (second)
Mean value of past T seconds is calculated.
Difference between AVE and AVEH are the following.
AVE
AVEH
Sampling cycle
1 second
0.1 seconds
Range of T
1 to 3600
1 to 300
7) Past data
Entering method of the formula
OLD (X#T)
OLDH (X#T)
X: Data channel number, T: Time in which go back (second)
Mean value of past T seconds is calculated.
Difference between OLD and OLDH are the following.
OLD
OLDH
Sampling cycle
1 second
0.1 seconds
Range of T
1 to 3600
1 to 300
8) First-order leg filter
Entering method of the formula
IIR (X#T)
X: Data channel number, T: Time constant (second)
First-order calculate is performed in the data of channel X.
Contents of calculation
｛dt÷(dt+t)｝×（x-d）＋d
dt: Sampling cycle (0.1 seconds fixed), t: time constant, x: current value of channel X, d: previous
calculation result
9) Increment per time
Entering method of the formula
PLS (X#T)
X: Data channel number, T: Unit time (second)
Calculate increment per unit time T. X is specified from the channel that is set totalizer or the channel
that is selected pulse range in 37 to 44.
