Eaton HFX Series - Input Modes; Analog Configuration

EATON HFX Product Family Installation and Operation Manual E-ELCL-II002-E2 July 2019 25
HFX Product Family
The system conguration has a second tab, the
system cong conguration that enables the user
to congure settings for Regulator Voltage, CAN 1
Termination, Watchdog Time, and Low Memory
Fault threshold.
Note: That depending on the parameter, double clicking
the value in the appropriate value eld will either open
a drop down menu to select, allow direct editing or toggle
the variable (see picture below).
15.2 Input Modes
The controller has either 6, 10, 16 or 24 inputs
available for use, depending on the selected model.
The specic inputs are as follows:
• Congurable Analog/Digital Inputs
• Congurable Frequency/Digital Inputs
• Congurable Differential Frequency/Digital Inputs
These different congurations are possible through
selection of the appropriate mode in the PLC
conguration tab in the IDE (see screens below).
15.3 Analog Conguration
Figure 1: Analog/Digital Inputs I/O Mapping tab.
This is the area where analog or digit input values
are mapped to addresses. These variables are all
accessible in the application program.
Variables:
• AnalogInValue#: Analog value with units
dependent upon congured mode.
• AnalogInBinaryValue#: Digital value after debounce
and rising/falling voltage thresholds are applied.
Note: # above represents input numerical
16, 10, 6, or 4 of the inputs (depending on the model
chosen) can be congured as either Analog or Digital.
Both the Analog and Digital value have a name,
value, address, type and description associated.
The name can be altered by the programmer,
if desired. Analog Inputs are displayed in actual
engineering units depending on the mode
conguration (either Voltage – mV, Current – μA,
Resistance - Ω, or Temperature °C). Binary inputs are
evaluated as true or false and our bits.
