11.. . APPENDIX A: MASTER ICON FILE REFERENCE
USING THE OMP-MODL11-4
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.
Use This Channel for Voltage: Both the Thermocouple Icon and the VDC-2V
Icon utilize the same Interface Module hardware Configuration Switch
setting. Because of this capability, a Thermocouple Icon can be changed
into a VDC-LO Icon by simply clicking on the CHANGE button.
Thermocouple Type: Specify the type of thermocouple to be connected to this
channel.
Units: Specifies the temperature scale units that will be output from this icon.
Celcius and Fahrenheit are directly supported, however, conversion to other
units can be performed within a Program Net by adding a Math Icon onto
this icon’s output.
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 thermocouple 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.
