11.. . APPENDIX A: MASTER ICON FILE REFERENCE

USING THE OMP-MODL11-30

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.

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-8 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 100 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 resulting in technically

accurate but undesired data. By enabling the

debounce function, typical short duration contact

bounce will be filtered out.

Event input. To change this channel to an Output, click on the Change
