11.. . APPENDIX A: MASTER ICON FILE REFERENCE

USING THE OMP-MODL11-10

DC-HI; +/- 30 VDC FULL SCALE VOLTAGE INPUT ICON

FUNCTION:

Performs the analog channel selection, amplification, and A-D conversion for a DC

voltage input within the range of +/-30VDC from an MLIM-1 Interface Module.

INPUTS:

Hardware: No signal input shown on Net for Program Net connections.

Update Clock: Output is updated with new reading upon each Update Clock pulse

when Enable input is unconnected or Hi.

Enable: Processing of icon is allowed when Enable pin is unconnected or connected

and Enable signal is TRUE.

OUTPUTS:

Output Signal: Data type signal. The Units of the output are Volts.

ICON CONFIGURATION DIALOG BOX:

CONFIGURATION OPTIONS:

Icon Name: Specify the name for the channel. This name will show directly under the

icon within the Program Net. If no name is User provided, the Backplane

Port (1 to 6) and Channel (A to D) where the actual Interface Module

channel is installed will be used for the name.

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.

Range: Specify the input range to be used for this channel. Select the range so

that anticipated input signal fluctuations will not exceed this Full Scale

range. If the input exceeds the selected range, an over-range value will be

logged.

AC Noise Reject: Enables software filtering of 50Hz or 60Hz noise on inputs. See

Appendix for an explanation of the 50/60 Hz filtering technique.

Filtering: First order noise filtering can be enabled during channel reading. First

order filtering reduces high frequency noise that may be picked up by

sensor wiring with the cost that it slows down the rate at which a channel

can be sampled. See Appendix for discussion on use of filtering.
