(1) The 32-bit floating decimal point data from device designated by
and 32-bit floating decimal
point data from device designated by
as A normally-open contact, and performs comparison
operation.
(2) The results of the comparison operations for the individual instructions are as follows:
Note that use of the E= instruction can on occasion result in situations where
errors cause the two values to not be equal.
Basic model QCPU: The upper five digits of the serial No. are "04122" or larger.
