Processing details
• These instructions perform a comparison operation between the single-precision real number in the device specified by
(s1) and the single-precision real number in the device specified by (s2). (Devices are used as a normally open contact.)
• The following table lists the comparison operation results of each instruction.
• When an input value is set from the engineering tool, a rounding error may occur.
Operation error
There is no operation error.
When the E= instruction is used, note that values in the devices may not be equal.
(1): Values in the devices may not be equal.
