Configuring Analog I/O
One of the I/O Expansion choices is “nLC-IO-4AI”. This expansion module provides four
analog devices. When selected, the “Configure” button is active. Clicking the “Configure”
button displays the “nLC-IO-4AI” dialog box (see Figure 3-4) that configures the four analog
inputs on this device.

The nLC-IO-4AI” configuration dialog box
Each analog device (A-00 to A-03) has three parameters:
–
“Mode” is a drop-down that provides the following choices:
•
Current 4-20 mA
•
Unipolar 0-10 Volts (default)
•
Bipolar +/-10 Volts
–
“Scaling” has two configurable values for “Lower Value” and “Upper Value”. The range
of values for each of these scaling parameters is from -10000 to 10000. Scaling is a
technique for converting input voltages (or amperage) to an integer value (see
Operator Panel
Use the drop-down list to indicate whether or not the nanoLC has an Operator Panel.
Currently, the only available selections are “None” and “nLC-OP1-LCD-032-4x20”.
Configure the “Fault Action” for the Operator Panel using the drop-down list. A fault occurs
when the project expects an Operator Panel and the nanoLC doesn’t have one. Choices for
handling faults are:
–
“Fault” sets a fault condition and stop execution
–
“Warning” sets a warning condition and continue execution
–
“Warning on Access” sets a warning condition only if the project attempts to access the
device and continue execution
–
“Ignore” continues execution without posting a warning or fault condition
