PLS, PLF
: Pulse conversion device (bits)
Function
PLS
(1) Turns ON the designated device when the execution command is turned OFF ON, and turns OFF the device in any
other case the execution command is turned OFF ON (i.e., at ON ON, ON OFF or OFF OFF of the execution
command).
When there is one PLS instruction for the device designated by during one scan, the specified device turns ON one
scan.
See Page 115, Section 3.9 for the operation to be performed when the PLS instruction for the same device is executed
more than once during one scan.
(2) If the RUN/STOP key switch is changed from RUN to STOP after the execution of the PLS instruction, the PLS
instruction will not be executed again even if the switch is set back to RUN.
(3) When designating a latch relay (L) for the execution command and turning the power supply OFF to ON with the latch
relay ON, the execution command turns OFF to ON at the first scan, executing the PLS instruction and turning ON the
designated device.
The device turned ON at the first scan after power-ON turns OFF at the next PLS instruction.
