11... APPENDIX A: MASTER ICON FILE REFERENCE
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
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.
