1. To specify the number of input and output words, place
the cursor in the box and backspace to delete. Enter the
desired selection.
Changing the number of input (read) words generates
the amount of input and status area mapped into
adapter memory. Changing the amount of output (write
words) causes the adapter to expect more
output/configuration words from the process.
2. The Data Description" button brings up a
screen (2a) which shows which input and
output words are being used. Clicking on
the boxes will automatically select the
number of words used. After selection, click
on the OK button to return to the module
configuration screen.
3. Select the module data type by clicking
on the list box. A list of types is displayed
(3a). Click on the desired module data
type to select.

for selection of each type. Click on the desired RTD to select.
6. The set to I/O only" button returns all settings
to real time settings for this type of module.
These settings are optimal, and not
necessarily the out of box" settings.

to save the settings to the adapter.
8. If you change the settings, when all selections are
complete, click on the OK button.

In the enhanced mode, inputs are compared
against a known, precision resistor to determine
the value of the RTD. Since this is performed each
scan, module throughput is decreased.
10. Clicking on the calibration button brings up the
calibration screen. In order to calibrate the
module, you must physically attach reference
