Current Applications When the condition occurs because a wire is disconnected:
• Input data for that channel changes to the scaled value
associated with the underrange signal value of the selected
operational range in floating point mode (minimum possible
scaled value) or -32,768 counts in integer mode.
• The ChxUnderrange (x=channel number) tag is set to 1.
When the condition occurs because the RTB has been
disconnected from the module (1756-IF6I module only):
• Input data for that channel changes to the scaled value
associated with the overrange signal value of the selected
operational range in floating point mode (maximum possible
scaled value) or 32,767 counts in integer mode.
• The ChxOverrange (x=channel number) tag is set to 1.
