or outside the setting range.
• The condition operator is a bit operator, and the
parameter 1 is 32 or more.
• An unusable condition operator is set for the set
condition.
• The conditional operator has been [parameter 1
> parameter 2] with 05H (P1

**

P2).
• The value in 'address' is out of the setting range
when the condition target is set to 'Buffer memory
(1-word/2-word)'. (1-word: 0 to 32767, 2-word: 0
to 32766)
