Clear signal device specification method:
1) Write the CLEAR signal output (Y) device number in "Clear signal device specification" device by a
hexadecimal number (expressed octal numbers).
e.g. setting H0010 means Y010. When setting H0008, an operation error occurs because Y008 does not
exist.
2) Turn on "CLEAR signal output enable" flag and "Clear signal device specification function enable" flag of
the pulse output designation device to specify the CLEAR signal device.
3) Execute DSZR instruction (zero return instruction with DOG search function) or ZRN instruction (zero
return instruction).
Example of program:
The following figure shows a program that can specify Y010 as the CLEAR signal output device for Y000
(pulse output destination device):

Change in Logic of Near-Point (DOG) Signal (DSZR Instruction)

Turn on or off "DOG signal logic reverse" flag to specify the logic of the near-point (DOG) signal of DSZR
instruction (zero return instruction with DOG search function). Use the operand (
specify the near-point (DOG) signal.

Change in Logic of Zero-Phase Signal (DSZR Instruction)

Turn on or off "Zero point signal logic reverse" flag to specify the logic of the zero-phase signal of DSZR
instruction (zero return instruction with dog search function). Use the operand (
specify the zero-phase signal.

4.3 Various Flags for Operation Commands
Specifies the Y010 as the CLEAR signal output device for the
Y000 (pulse output destination device).
Turns on "CLEAR signal device designation function enable"
flag of the Y000 (pulse output destination device).
Turns on "CLEAR signal output enable" flag.
Description of setting
Positive logic (Turning on the input will turn on the near-
point signal.)
Negative logic (Turning off the input will turn on the near-
point signal.)
Description of setting
Positive logic (Turning on the input will turn on the zero-
phase signal.)
Negative logic (Turning off the input will turn on the zero-
phase signal.)
