Relational Computation
The data that can be used in equations are measured values, computed values, constants, communication input
data, and remote control input terminal status. You can specify a computing equation that performs relational
computation on a computing element. (Example: 01.LT.ABS(02))
Equation Examples
02.LT.03
If the measured value of channel 2 is less than the measured value of channel 3, the computed result is “1.”
Otherwise, the result is “0.”
02.GT.03
If the measured value of channel 2 is greater than the measured value of channel 3, the computed result is “1.”
Otherwise, the result is “0.”
02.EQ.03
If the measured value of channel 2 is equal to the measured value of channel 3, the computed result is “1.”
Otherwise, the result is “0.”
02.NE.03
If the measured value of channel 2 is not equal to the measured value of channel 3, the computed result is “1.”
Otherwise, the result is “0.”
02.GE.03
If the measured value of channel 2 is greater than or equal to the measured value of channel 3, the computed
result is “1.” Otherwise, the result is “0.”
02.LE.03
If the measured value of channel 2 is less than or equal to the measured value of channel 3, the computed
result is “1.” Otherwise, the result is “0.”
Logical Computation
Checks whether the two data values, e1 and e2 (e1 only for NOT), are zeroes or non-zeroes, and computes
according to the conditions. The data that can be used in equations are measured values, computed values,
constants, communication input data, and remote control input terminal status. You can specify a computing
equation that performs logical computation on a computing element.
AND
Logical Product
(Syntax)
e1ANDe2
(Condition) If the two data values e1 and e2 are both non-zeroes, the computed result is “1.” Otherwise,
it is “0.”
(Explanation) e1 = 0, e2 = 0 : e1ANDe2 = 0
e1 =/ 0, e2 = 0 : e1ANDe2 = 0
e1 = 0, e2 =/ 0 : e1ANDe2 = 0
e1 =/ 0, e2 =/ 0 : e1ANDe2 = 1
