Description
W-UE
• When input relay 0000 is ON, the output operand turns ON at the rising edge of
the input operand.
W-DE
• When input relay 0002 is ON, the output operand turns ON at the falling edge of
the input operand.
Note 1: If the input operand is already ON before input relay 0000 turns ON, the
output operand does not turn ON.
Note 2: The W-UE/W-DE instruction must be used in subroutine programs that are
executed every scan time (because rising and falling edges cannot be recognized).
Note 3: Output operand relay Nos. for W-UE/W-DE instructions cannot be dupli-
cated in a program.
Operands
* Note that of I/O Nos. 7000 to 9915, those that are not assigned to expansion or
remote I/O unit ports can be used for internal utility relays.
