Relational Computation
The types of data that can be used in equations are measurement channels,
computation channels, constants (K01 to K12), communication interface data (C01 to
C12), and the remote control terminal conditions (D01 to D08). You can specify a
computing equation that performs relational computation on a computing element
(Example : 01.LT.ABS(02)).
EXAMPLE :
02.LT.03
The computed result will be “1” if the measured value in channel 2 is less than the
measured value in channel 3, otherwise the value will be “0”.
02.GT.03
The computed result will be “1” if the measured value in channel 2 is greater than the
measured value in channel 3, otherwise the value will be “0”.
02.EQ.03
The computed result will be “1” if the measured value in channel 2 is equal to the
measured value in channel 3, otherwise the value will be “0”.
02.NE.03
The computed result will be “1” if the measured value in channel 2 is not equal to the
measured value in channel 3, otherwise the value will be “0”.
02.GE.03
The computed result will be “1” if the measured value in channel 2 is greater than or
equal to the measured value in channel 3, otherwise the value will be “0”.
02.LE.03
The computed result will be “1” if the measured value in channel 2 is less than or equal
to the measured value in channel 3, otherwise the value will be “0”.
Logical Computation
The computation is performed using e1 and e2 which are identified as either “zero” or
“non zero”. The types of data that can be used in equations are measurement channels,
computation channels, constants (K01 to K12), communication interface data (C01 to
C12), and the remote control terminal conditions (D01 to D08). You can specify a
computing equation that performs relational computation on a computing element.
AND Logical product
