SERIAL PORTS displays port information on
all available ports.
Pressing the NEXT or PREVIOUS pushbutton
allows cycling through ports. Pressing the
CANCEL pushbutton will return the display to
the Main Menu.
DIAGNOSTICS displays information for factory
field service.
REDUNDANCY INFO displays the current
status of all redundancy related faults. It can
be used to monitor the health of the master
and standby controllers. It can also be used
for diagnostic purposes.
Redundancy faults originate from three general
areas:
• Self detected internal failures of the master
controller
• Inter-controller communications
• A failure in the standby controller.
Any redundancy fault is annunciated by the
master controller, and the redundancy fault
code of the highest priority fault is displayed.
The controller also provides a diagnostic menu
for more detailed information on the source
of a redundancy problem. All redundancy
related faults must be cleared to insure proper
redundancy operation.
Fault
Displays the current redundancy fault.
Lst Flt
Displays the last redundancy fault that
occurred.
Cntr Mode
Indicates whether the controller is in master or
standby mode.
My Cong
Indicates whether the controller is the primary
or secondary controller.
Redun Mem
Displays how long it takes to transfer the local
and global memory between controllers.
HSSL Status
An error is generated when a problem is
detected on the high-speed communication link
between controllers. This fault is annunciated
when the standby controller is offline.
Version Match
To ensure proper redundant operation, the
firmware versions of redundant controllers
must match. This error is set when a mismatch
is detected. Consult the factory for firmware
upgrades.
SIL Rating
To ensure proper redundant operation, the SIL
rating of redundant controllers must match. An
error is indicated if a SIL controller is paired
with a non-SIL rated controller. Consult the
factory for details.
Parser
As the master controller configures a standby
controller, configuration information is extracted
from non-volatile memory and checked for
errors.
Comm Ack
Critical information is exchanged between
controllers on the HSSL using acknowledged
messages. The master sends data packets that
contain an embedded CRC and a transaction
number. The standby validates the message
by calculating and comparing the CRC values.
If the CRC is correct the standby saves the data
and returns an acknowledge message with
the transaction number. If an acknowledge
message with the proper transaction number
is not received by the master within the allotted
time the message is resent. When all retries
are used the acknowledge error is indicted and
acknowledged communication is terminated.
