The “Input Selection...” dialog box presents the database as a hierarchical list of sources. Any item on the list
that has a “+” before it has subordinate items and clicking on the “+” will expand the list showing all items that
make up that category.
To the right of the list are two buttons that can “Collapse All” or “Expand All” subordinate items in the list for
easy viewing. The first nineteen items on the list provide access to controller status information and the globals
database. The “LON” item will allow access to all field device information, the “Relays” item is for accessing the
controllers onboard relay status.
In the example to the right, the “LON” category has been
expanded to reveal the field devices and then a Point
IR Gas Detector (PIRECL) tagged “ECL-015” has been
expanded. The data available for this device exceeds
the window length and the list has become “scrolling” to
accommodate the expanded data.
In this example, a “Boolean*” or “Binary” data element
named “High Gas Alarm” has been selected by clicking
on it with the mouse. Its selection is noted by its text
description being highlighted.
The “block” with a letter preceding the data points name
indicates the “Data Type” for that point.
The NOT gate in our example network requires a “Binary”
data type for both inputs and outputs. The “High Gas
Alarm” selected meets this criteria.
Selecting the “OK” button closes the “Input Selection...”
dialog box and “links” the “ECL-015 High Gas Alarm” to
the “Input Variable” of the example network, as shown
below.
*Note
For detailed “Data type” definitions, structures and ranges, refer to section 13-67.
