4) When the command input is set to ON, the operation is started. The timing clock output destination device
is set to ON or OFF by the END instruction.
Even if the command input is set to OFF, the operation is not stopped.
In the STOP mode, the operation is suspended. When the power to the PLC is turned OFF, the operation is
stopped.
Even if the command input is set to OFF, the operation is not stopped.
In the STOP mode, the operation is suspended. When the power to the PLC is turned OFF, the operation is
stopped.
5) When "n1" and "n2" are set to "0", the device
is set to the following status:

Caution
• The DUTY (FNC186) instruction can be used up to 5 times (points).
It is not permitted, however, to use the same timing clock output destination device
for two or more DUTY
(FNC186) instructions.
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When "n1" and/or "n2" is less than "0" (error code: K6706)
D8067.
• When "n1" and/or "n2" is less than "0" (error code: K6706)
• When any device other than M8330 to M8334 is set to
(error code: K6705)
Program example
In the program shown below, when X000 is set to ON, M8330 is set to ON for 1 scan and OFF for 3 scans.
