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 Config
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.
