Applicable devices
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.
• If the data in the device specified by (s1) or (s2) is out of the range of setting data, the operation result will be non-continuity
(ENO OFF).
• If the LDE_
instruction is used in the program written in FBD/LD, use a left rail or a variable/constant which is always on
for EN.
• If the ORE_
instruction is used in the program written in FBD/LD and EN is set to TRUE, ENO turns on. EN will not be an
execution condition.
• When an input value is set using the engineering tool, a rounding error may occur. Refer to the following for the precautions
on setting input values using the engineering tool.
Operation error
There is no operation error.
Note that two values may not be equal due to an error when the E= instruction is used.
(1) Two values may not be equal.
