(a) GT, GT_E(>) Performs comparison of [ > ]&[ > ]&···&[ (n−1) > (n)].
• Outputs TRUE if all of comparisons satisfy
(n−1) > (n).
• Outputs FALSE if any of comparisons satisfies
(n−1) (n).
(b) GE, GE_E( ) Performs comparison of [ ]&[ ]&···&[
(n−1) (n)].
• Outputs TRUE if all of comparisons satisfy
(n−1) (n).
• Outputs FALSE if any of comparisons satisfies
(n−1) < (n).
(c) EQ, EQ_E(=) Performs comparison of [ = ]&[ = ]&···&[
(n−1) = (n)].
• Outputs TRUE if all of comparisons satisfy
(n−1) = (n).
• Outputs FALSE if any of comparisons satisfies
(n−1) (n).
(d) LE, LE_E( ) Performs comparison of [ ]&[ ]&···&[
(n−1) (n)].
• Outputs TRUE if all comparisons satisfy
(n−1) (n).
• Outputs FALSE if any of comparisons satisfies
(n−1) > (n).
(e) LT, LT_E(<) Performs comparison of [ < ]&[ < ]&···&[
(n−1) < (n)].
• Outputs TRUE if all comparisons satisfy
(n−1) < (n).
• Outputs FALSE if any of comparisons satisfies
(n−1) (n).
(f) NE, NE_E(< >) Performs comparison of [ ].
• Outputs TRUE if .
• Outputs FALSE if = .
(2) The number of pins of variable 's' can be changed in the range from 2 to 27. (The number of
pins of variable 's' for comparison operator NE(_E)) is fixed at and .
Operation result
(1) Function without EN/ENO
An operation is executed and the operation value is output from .
(2) Function with EN/ENO
The following table shows the executing conditions and operation results.
*1 When FALSE is output from ENO, the data output from is undefined.
In this case, create a program so that the data output from is not used.
