Description
Click the point number to configure parameters for the specified point (0...15).
Check which points trigger production of data on Change of State. If the box is
checked, Change of State is enabled for a particular state transition that by the
column header indicates. If the box is unchecked, Change of State is disabled.
Enable Change of State appears dimmed only when in Hard Run mode (0...15).
Choose from the following three pre-selected threshold types for each point:
• Full – Thresholds are used that work with the Rockwell Automation preferred end-
of-line devices to support open-wire and short circuit protection and diagnostics.
• None – Thresholds are used that are appropriate for use with no end-of-line device.
This option does not support open-wire and short circuit protection and
diagnostics.
• Custom – You provide the thresholds. The default matches the Full thresholds.
Click Edit to display the Edit Custom Thresholds dialog box and edit thresholds for the
selected point.
When offline or online (including Hard Run mode), the Edit button is enabled when the
Custom diagnostics type is selected for a point and dimmed when the Full or None
diagnostic types are selected. When the Custom diagnostic type is selected, the
default matches the Full thresholds.
Select if the thresholds allow for open wire detection (for example, if the threshold 2
value is not 0). By default, the header checkbox is selected and all points (0...15) are
selected. If the header checkbox is cleared, all points (0...15) are cleared.
To select open wire detection for a specific point, check the checkbox in the
appropriate row for that point.
To clear open wire detection for a specific point, clear the checkbox in the appropriate
row for that point.
Select if line fault alarms are latched until reset (including Open Wire Detection and
Short Circuit detection). By default, the header checkbox is selected and all points
(0...15) are selected. If the header checkbox is cleared, all points (0...15) are cleared.
Click Reset to reset the diagnostic latch serviced.
Select whether Change of State is enabled when any diagnostic event occurs.
Specifies that a custom end device must be used when using full or custom
diagnostics.
