Table 32 - Configuration Parameters for Duplex Mode
Parameters Description
Point Click the point number to configure parameters for the specified point (0…15).
Enable Change of State 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 indicated by the column header. If the box is
unchecked, Change of State is disabled.
Enable Change of State appears dimmed only when in Hard Run mode (0…15).
Diagnostics 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.
Custom 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.
Open Wire Detection 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.
Latch Diagnostics 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.
Reset Latch Diagnostics Click Reset to reset the diagnostic latch serviced.
Enable Change of State for Diagnostic Transitions Select whether Change of State is enabled when any diagnostic event occurs.
Full And Custom Diagnostics Require Use Of An Appropriate End-of-line Device Specifies that a custom end device must be used when using full or custom diagnostics.
