Harmony Area Controller (HAC)

Appendix C

Memory Utilization and Execution Times

This section lists the module memory requirements for each
function code. Three quantities are given for the HAC memory
utilization:

• The number of bytes of nonvolatile random access memory

(NVRAM). The Harmony area controller has a total configu-
ration memory of 2,097,150 bytes of NVRAM.

• The number of bytes of random access memory (RAM). The

Harmony area controller has a total configuration memory
of 6,291,392 bytes of RAM.

• The checkpoint buffer RAM contained on the process I/O

(PIO) board inside the HAC enclosure. This area is physi-
cally separate from the main memory board, and it can
have an impact on the size of a configuration. The check-
point buffer RAM has a total configuration memory of
2,070,000 bytes.

This section also lists the function code execution times (in
microseconds) for the Harmony area controller.

NOTE: Except where otherwise noted, execution times are given for worst
case conditions.

Table C-1 shows the HAC memory requirements and the exe-
cution time for each function code.

NCD1 02 Network I/O board channel one failure: 0 = no, 1 = yes
NCD2 01 Network I/O board channel two failure: 0 = no, 1 = yes
10 PRI 80 Primary/backup status: 0 = backup module, 1 = primary module
CFC 40 Configuration current (latched until backup is reset):
0 = configuration initialization not complete.
1 = all configuration initialization complete.
CHK 10 Backup has completed check pointing (latched until backup is reset).
0 = no, always set to 0 on the primary module.
1 = yes
RID 08 Redundancy ID. Indicates position on the backplane:
0 = left position, 1 = right position
RDEXP 04 Redundant module expected.
0 = no.
1 = yes, always set to 1 on the backup module.
Follows state of function code 90, specification S3 on the primary module.
OCE 02 Online configuration is enabled: 0 = no, 1 = yes.
RDDET 01 Redundant module detected: 0 = no, 1 = yes.
Latched until module is reset or it changes from backup to primary or primary
to backup.

 Module Status Information - HAC

Table C-5. Byte Description - HAC (continued)

Field Size
Byte Field Description
or Value
11 PA 80 24 VDC logic power input A status: 0 = good, 1 = bad
PB 40 24 VDC logic power input B status: 0 = good, 1 = bad
PS 20 Internal power system non-fatal error: 0 = good, 1 = bad.
Status display on the HAC must be checked for further information on the
cause of the PS flag being set.
SOA 10 Status output alarm: 0 = good; 1 = bad.
Indicates the status of the system +24 volt power and the I/O block’s power
(logic and field power) for a single cabinet.
RNO 08 Redundancy NVM overrun (latched indication):
0 = no.
1 = yes, set to 1 in primary module if NVM checkpoint overruns
have occurred.
NVM checkpoint overruns cause the primary module to reset the backup
module.
NOL 04 Network I/O board offline: 0 = no, 1 = yes.
FDNL 02 Firmware download in progress: 0 = no, 1 = yes
BFM 01 Backup firmware mismatch:
0 = no.
1 = yes, backup has determined the primary firmware revision is different
from its own.
12 NODES3 80 Nodes offline: 0 = no, 1 = yes
RER1 40 Receive errors on loop channel 1: 0 = no, 1 = yes
RER2 20 Receive errors on loop channel 2: 0 = no, 1 = yes
TER1 10 Transmit errors on loop channel 1: 0 = no, 1 = yes
TER2 08 Transmit errors on loop channel 2: 0 = no, 1 = yes
RID1 04 Receiver idle on loop channel 1: 0 = no, 1 = yes
RID2 02 Receiver idle on loop channel 2: 0 = no, 1 = yes
RCF 01 Local Cnet loop communication failure: 0 = no, 1 = yes
14 — FF Module nomenclature: 0x08 = HAC
15 — FF Revision letter (in ASCII code). For example, 0x41 = A
16 — FF Revision number (in ASCII code). For example, 0x30 = 0
NOTES:
1. The error description corresponding to byte 3 is displayed on the front panel LCD display when the module is in ERROR mode.
2. All block numbers are encoded in hexadecimal, with (1) equaling the most significant digits and (2) equaling the least signifi-
cant digits. Example: (1) = 4E, (2) = 20 is block number 20,000.
3. Active only when the controller is in execute mode.
