This page displays additional configuration parameters for pulse/discrete inputs. Select type, then set additional parameters as applicable. State inputs produce a value of 0 or 1 in the respective binary input object. Frequency or count inputs produce a value in the respective analog input object scaled by slope and intercept.

If type is State and invert is checked, the value reflected by the object will be the inverse of the physical input. Normally 1=ON, but with invert checked, 1=OFF.

Slope and intercept are intended primarily to scale data values when the input is configured as a frequency input. A typical application is converting tachmeter frequency to an RPM reading. (Note that maximum input voltage is +24V/-0V.) Slope and intercept will be calculated for a state input, but will not be calculated for a total count input.

Total counts are non-volatile over the long term. The counts are stored to non-volatile memory (EEPROM) every 15 minutes. Therefore loss of power only results in a maximum of 15 minutes of data. EEPROM does have a finite life measured in write cycles. Storing count information no more often than once every 15 minutes is expected to yield a product life in excess of 25 years.
