11.. . APPENDIX A: MASTER ICON FILE REFERENCE
USING THE OMP-MODL11-24
Output Name: Specify a name for the Output signal from this icon. This Output
Name will be referenced by other icons downstream in the Program Net.
Units: Provides a text box for User entry of a units label that will be shown at the
output from this icon. Conversion to other units can be performed within a
Program Net by adding a Math Icon onto this icon’s output.
Event / Counter / Frequency Select EVENT for the Event function.
Debounce: Enables a hardware filter circuit that prevents short duration transitions
from passing into the icon. Debounce can be used to filter out contact
bounce from mechanical switches. The MLIM-2 Debounce has a time
constant of approximately 50mS. Note that the use of Debounce will delay
the actual input to output transition time by 50 to 200 mS.
FYI: Contact bounce is a phenomenon that
occurs when a mechanical switch opens or
closes. During switching, the physical electrical
contacts inside the switch bounce against each
other a number of times before they settle to
their final state.
Depending on the duty cycle of the contact
bounce, the OMP-MODL may count these
bounces as events or transitions (count mode)
resulting in technically accurate but undesired
data. By enabling the debounce function, typical
short duration contact bounce will be filtered out.
Output TRUE when Input is HIGH / LOW: Allows logical reversal of the Output with
respect to the input state.
