8) You can enable the ag bit to release the high-speed output port resources, so that the next
pulse output instruction is started immediately without disabling the previous instruction ow.
The "port output initialization ag bit" of special elements must be set. See the following table.

If the ow of the pulse output instruction A is active, the instruction occupies the high-speed output port no
matter whether the pulse output is nished. No pulse will be output no matter whether the ow of the pulse
output instruction B using the output port is active. Because the resources of this high-speed output port
have been occupied by the instruction A, an error indicating port duplication or conict is returned. In this
case, you can enable the output initialization ag bit of this port to release the port resources, and then
pulses are output when the ow of the pulse output instruction B using the output port is active.

As shown in the preceding gure, M100 is active, and drives Y0 to output 20,000 pulses at a frequency
of 1000 Hz. If the output is driven by M100 but the user wants to set M200 to ON to immediately start the
output (SET M8351 in the preceding gure), the high-speed output driven by M100 stops immediately, the
instruction driven by M200 occupies the high-speed output port Y0, and the set high-speed output starts
immediately.
