• If the comparison target data in the device are not recognized as time data, SM709 turns on after the instruction is executed
and the operation result will be non-continuity. If the device areas specified by (s1) to (s1)+2 or (s2) to (s2)+2 exceed the
corresponding device range, SM709 turns on after the instruction is executed and the operation result will be non-continuity
as well. Once SM709 turns on, the on state is held until the CPU module is powered off or reset. Turn off SM709 as
needed.
• The following table lists the comparison operation results of each instruction.
Ex.
The time data A, B, and C are compared.
• The following table lists the comparison operation results between A, B, and C. Even when the data are compared under
the same conditions, the results differ depending on the comparison target data.
Operation error
There is no operation error.
