[Function] Turn ON the specified output port or flag for the specified time.
When this command is executed, the output port or flag specified in operand 1 will be turned
ON and then the program will proceed to the next step. The output port or flag will be turned
OFF automatically upon elapse of the timer setting specified in operand 2.
The timer is set in a range from 0.01 to 99.00 seconds (including up to two decimal places).
(Note 1) If this command is executed with respect to an output port or flag already ON, the output
port or flag will be turned OFF upon elapse of the timer setting.
(Note 2) If the program ends after the command has been executed but before the timer is up, the
output port or flag will not be turned OFF.
(Note 3) This command will not be cancelled by a TIMC command.
(Note 4) A maximum of 16 timers, including BTPN and BTPF, can be operated simultaneously in a
single program. (There is no limitation as to how many times these timers can be used in a
single program.)
[Example] BTPN 300 1 Turn ON output port 300 for 1 second.
BTPN 600 10 Turn ON flag 600 for 10 seconds.
(Note 5) This command cannot be used to output pulses for a specified period because a margin of
error occurs in the pulse output time if other task or interruption process occurs after the port
is turned ON until it is turned OFF.

The output port or flag turns ON here, after
which the program will proceed to the next step.
