RX3i Ethernet NIU 9
GFK-2419M
Subject Description
Loss of Power Supplies after
firmware update
A Loss of Power Supplies after firmware update may occur. This does not happen
with all firmware updates and will not occur if the system is power cycled after the
firmware upgrade has completed. The following fault is displayed when this issue
occurs:
Loss of, or missing option module
Error Code 36
Group 4
Action 3:Fatal
Task Num 9
Fault Extra Data: 01 58 02 4f 80 08 0a 07 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00
To correct this condition, power cycle the system.
Battery installation
When installing a new battery, when there currently is no battery installed, the
battery must be installed while the CPU has power. Failing to follow this procedure
could result in the CPU not powering up.
If a battery is installed while power is off (and there was no battery previously
installed), and the CPU fails to power up, simply remove the battery, power cycle
the CPU and then install the battery.
Hot Swapping some Analog
modules slowly result in
modules not being
recognized
Occasionally during a hot insertion (hot swap) of IC695 Non-Isolated Analog Input
Modules, input channels may take up to 2 seconds to reflect actual input values
after the module ok bit is enabled in the module status word. This only occurs
when hot insertion has been done slowly (i.e. approximately 1.5 seconds to insert
the module).
Ethernet Disconnect During
Word for Word Change
If the Ethernet connection is broken during a word–for-word change, the
programmer may not allow a subsequent word-for-word change after reconnecting.
Recommendation: go offline and then back online again.
Simultaneous Clears, Loads
and Stores Not Supported
Multiple programmers may not change ENIU contents at the same time. The
programming software may generate an error during the operation. Simultaneous
loads from a single ENIU are allowed.
Power Cycle During Write to
Flash
The ENIU is configured to power up from flash and if is power-cycled while writing
to flash, a fault is generated on power up.
Hardware Configuration Not
Equal After Changing Target
Name
If a hardware configuration is stored to flash and the name of the target is
subsequently changed in the programming software, the hardware configuration
will go Not Equal and will not Verify as equal.
Controller and IO Fault
Tables May Need to be
Cleared Twice to Clear
Faulted State
Both Controller and IO fault tables may need to be cleared to take the ENIU out of
Stop/Fault mode. If one of the tables contains a recurring fault, the order in which
the tables is cleared may be significant. Recommendation: if the ENIU is still in
Stop/Fault mode after both tables are cleared, try clearing the fault tables again.
Setting Force On/Off by
Storing Initial Value
After a force on or force off has been stored to the ENIU, it cannot be switched
from force on to force off or vice-versa by downloading initial values.
Recommendation: turn off the force by doing a download, and then change the
force on or off by another download.
Number of Active Programs
Returned as Zero
The SNP request Return Controller Type and ID currently returns the number of
active programs as zero.
Serial I/O Failure at 115K
During Heavy Interrupt Load
Rarely, data corruption errors occur during serial communications when running at
115K if there is a heavy interrupt load on the ENIU. Recommendation: under heavy
load applications, restrict serial communications to 57K or lower.
SNP ID not always provided
Unlike the Series 90-30, the RX3i ENIU’s SNP ID does not appear in the Machine
Edition programmer Show Status display. Service Request 11 will always return
zeros.
Second programmer can
change logic while in Test &
Edit mode
While currently active in a Test and Edit session using Machine Edition on one PC,
Machine Edition running on another PC is not prevented from storing new logic to
the ENIU.
