Module Faults in the RX3i I/O Fault Tables
Module faults from the Genius Devices downstream from the GCG001 Genius Gateway are passed to the
PROFINET Controller and then to the PLC, where the
y are visible in the PLC’s I/O Fault Table
. For details on the
operation of the RX3i Fault Table, refer to the
PACSystems RX7i, RX3i and RSTi-EP CPU Reference Manual,
GFK-2222 Chapter 14.
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
Description
Location
Identifies the location of the fault by bus and serial bus address (SBA).
CIRC No.
When applicable, identifies the specific faulted I/O point on the module
(enumerated 1-8 for an 8-point I/O block, for instance).
Variable Name
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 Unpublished I/O variables will not be displayed in this field.
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.
Fault Category
Specifies a general classification of the fault.
Fault Type
Consists of subcategories under certain fault categories. Set to zero when not applicable
to the category. See Section 5.4.1 below.
Date/Time
The date and time the fault was recorded by the CPU based on the RX3i CPU clock.
Details
To view detailed information, click the fault entry.
Note:
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.
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)
for Fault status related to devices on the bus.
These are not to be confused with the entries in the I/O Fault Table.
