8.2.2 LOGIC FUNCTIONS
AND
X1 ^ X2
Specify two measured or function data (X1, X2: only discrete signals). When both samples equal ‘1,’ ‘1’ is output. ‘0’
is output for all other combinations.
OR
X1 ^ X2
Specify two measured or function data (X1, X2: only discrete signals). When both samples equal ‘0,’ ‘0’ is output. ‘1’
is output for all other combinations.
NOT
¬ X1
Specify one measured or function data (X1, only discrete signal). An output of opposite logic to an input is provided.
XOR
X1 ^ X2
Specify two measured or function data (X1, X2: only discrete signals). When one sample’s logic matches the other,
‘0’ is output. When it does not, ‘1’ is output.
8.2.3 MATH FUNCTIONS
Square root
K1√X1
Specify measured data or function data (X1), with a coefficient (gain K1).
Power
X1 A1
Specify measured data or function data (X1), with a constant (exponent A1).
8.2.4 ACCUMULATION
Analog accumulation
Specify measured data or function data (X1), with Reset condition.
The measured (function) data is accumulated until it is reset when the reset condition is true or when Start key is
touched. In order to reset the hold function, ‘Time’ or ‘Trigger input’ can be specified.
Reset Time 30 min., 1 hour, 2 hours, 3 hours, 4 hours, 6 hours, 12 hours,
24 hours (selectable time of a day)
Trigger input Rise, Sink, ON, OFF.
Input X1, such as flow signals, could be values per time unit (/day, /hour, /min, /sec). In order to accurately totalize
this type of signals, specify the time unit. For example, without the time unit setting, with 1-minute storing interval, 500
m
3
/h data input, 500 is added every 1 minute, up to 30000 m
3
/h. With the time unit setting, only one-sixtyth (1/60) of
the input data is counted by every storing interval.
Sum scale None ∑ (input or function data)
Sec ∑ (input or function data) x (3600/GAIN)
Min ∑ (input or function data) x (60/GAIN)
Hour ∑ (input or function data) x (1/GAIN)
Day ∑ (input or function data) x (0.04166/GAIN)
