I/O Fault Table
The I/O Fault Table displays I/O faults such as circuit faults, address conflicts, forced circuits, I/O
module addition/loss faults and I/O bus faults.
The fault table displays a maximum of 64 faults. When the fault table is full, it displays the earliest 32
faults (33—64) and the last 32 faults (1—32). When another fault is received, fault 32 is shoved out of
the table. In this way, the first 32 faults are preserved for the user to view.
The I/O Fault Table provides the following information for each fault:
Location
Identifies the location of the fault by rack.slot location, and sometimes bus and
buss address.
CIRC No.
When applicable, identifies the specific I/O point on the module.
Variable
If the fault is on a point that is mapped to an I/O variable, and the variable is set
Name
to publish (either internal or external), the I/O Fault Table displays the variable
name. Unpublished I/O variables will not be displayed in this field.
Ref. Address
If the fault is on a point that is mapped to a reference address, this field
identifies the I/O memory type and location (offset) that corresponds to the
point experiencing the fault. When a Genius device fault or local analog module
fault occurs, the reference address refers to the first point on the block where
the fault occurred.
Note: The Reference Address field displays 16 bits and %W memory has a
Fault
Specifies a general classification of the fault.
Category
Fault Type
Consists of subcategories under certain fault categories. Set to zero when not
applicable to the category.
Date/Time
The date and time the fault occurred based on the CPU clock.

32-bit range. Addresses in %W are displayed correctly for offsets in the
16-bit range (≤65,535). For %W offsets greater than 16 bits, the I/O Fault
Table displays a blank reference address.
