Fault Types Reported To The Rx3I Controller I/O Fault Table - Emerson PACSystems RX3i User Manual

User manual
GFK-2892G
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 contents of the I/O Fault Table entry
are as follows:
Entry
Location
CIRC No.
Variable Name
Ref. Address
Fault Category
Fault Type
Date/Time
Details
Note:
As mentioned in Section 5.1, the GCG001 consumes three banks of 32 bits in %I as status
bits
a. for the GCG001 itself and
b. for the Genius bus devices, it controls and
c.
These are not to be confused with the entries in the I/O Fault Table.
5.4.1 Fault Types Reported to the RX3i Controller I/O Fault
Table
When imported into the Rx3i I/O Fault Table, the following Error Codes are displayed
without explanation. The following table is provided to assist in decoding the displayed error
codes.
Diagnostics
Description
Identifies the location of the fault by bus and serial bus address (SBA).
When applicable, identifies the specific faulted I/O point on the module
(enumerated 1-8 for an 8-point I/O block, for instance).
If the fault is associated with a point that is mapped to an I/O variable, and
the variable is set 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 Unpublished I/O variables will not be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.
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.
Specifies a general classification of the fault.
Consists of subcategories under certain fault categories. Set to zero when
not applicable to the category. See Section 5.4.1 below.
The date and time the fault was recorded by the CPU based on the RX3i
CPU clock.

The Reference Address field displays numbers that are expressed in the range 0.65535 (16-
bits.) 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.
