Using the High-Speed Counter and Programmable Limit Switch 129
High Preset Output (HPO)
The HPO (High Preset Output) defines the state (1 = ON or 0 = OFF) of
the outputs on the controller when the high preset is reached. See Output
Mask Bits (OMB) on page 127 for more information on how to directly
turn outputs on or off based on the high preset being reached.
The high output bit pattern can be configured during initial setup, or
while the controller is operating. Use the HSL instruction or the SP bit to
load the new parameters while the controller is operating.
Low Preset Output (LPO)
The LPO (Low Preset Output) defines the state (1 = “on”, 0 = “off”) of the
outputs on the controller when the low preset is reached. See Output
Mask Bits (OMB) on page 127 for more information on how to directly
turn outputs on or off based on the low preset being reached.
The low output bit pattern can be configured during initial setup, or while
the controller is operating. Use the HSL instruction or the SP bit to load
the new parameters while the controller is operating.
