Functions and actions
Because the relay is not applicable to high-frequency actions, this instruction is applicable only to the PLC
of the transistor output type. This instruction can be used to output S2 pulses at the S1 frequency through
the port specied by D. After the pulses are sent, the M8029 ag is set. Wherein:
D indicates the pulse output port which can be Y0, Y1, Y2, Y3, or Y4.
S1 indicates the designated output pulse frequency. For a 16-bit instruction (PLSY), the frequency ranges
from 1 Hz to 32,767 Hz. For a 32-bit instruction (DPLSY), the frequency ranges from 1 Hz to 200,000 Hz (that
is, 1 Hz to 200 kHz). The S1 value can be changed during instruction execution.
S2 indicates the number of the output pulses. For a 16-bit instruction (PLSY), the number ranges from 1 to
32,767. For a 32-bit instruction (DPLSY), the number ranges from 1 to 2,147,483,647. When S2 is 0, innite
pulses are sent continuously.
When the instruction ow status is OFF, the pulse output stops immediately. When the instruction ow
status switches from OFF to ON, the pulse output restarts. When the instruction is executed, the M8029
ag is set to ON.
