9 AFR - Automatic fault report


Interrelationships	Parameter Description
Functions of the AMO	Error Messages and Advisories

The AMO "AFR" can be used to control the three Logical Device Units (LDU) "Automatic Fault Report" (FAMAFR1,2,3). Wherever the term FAMAFR is referred to in this AMO description, the functions and/or procedures described apply in each case similarly to FAMAFR1, FAMAFR2 and FAMAFR3.
In addition, a high-priority fault report can be generated and sent to one FAMAFR each to test the entire transmission path and check out connection setup.
When fault transmission is deactivated, the fault reports in the memory are preserved, but no more fault reports are accepted from FAMAFR.
Fault reports generated in the system are transmitted by FAMAFR to the service center or to the respective fault recording unit connected;
The following parameters can be set for this purpose:

•

LDU (branch parameter - for whose FAMAFR the following applies)
Selection of an FAMAFR for which the initiated actions or the following parameters apply.
The parameter LDU can assume the values ’AFR1’, ’AFR2’, and ’AFR3’.

•

TYPE (selection parameter for activate or deactivate)
This parameter can be used to specify whether fault transmission (TYPE=LDU) is to be activated or deactivated and/or logging of fault reports on the service terminal (TYPE=PROT) is to be on or off.

•

PAR (selection parameter for add or change)
This parameter is used to specify whether the following parameters affect the fault transmission (PAR=LDU) or the fault pair list (PAR=TAB).

•

DEL (selection parameter for delete)
This parameters is used to specify whether entire fault pair list (DEL=ALL) or only one line of this fault pair list (DEL=LINE) is to be deleted. If only one line is to be deleted, its line number (FINO=1 ... 99) must also be specified.

Parameter list for fault transmission (PAR=LDU)

•

PRI (Priority Setting)
Each fault report is given a certain priority.
The parameter PRI defines the starting priority at which fault reports must be transmitted instantly, and the finishing priority at which fault reports must be stored in Hicom.
The highest priority is one, the lowest eight.

•

MAXF = Maximum number of high-priority fault reports which may be accepted during the supervision time.
If the maximum number of fault reports is exceeded, an avalanche fault report will be generated 'F0000 M5 AVALANCHE FAULT HIGH PRIORITY SEE AD AMO-AFR' and sent to the respective service center connected. After the avalanche report has been sent, FAMAFR is deactivated.

•

MAXFL = Maximum number of low-priority fault reports which may be accepted during the supervision time.
If maximum number of fault reports exceeded -> avalanche fault report will be generated 'F0000 M5 AVALANCHE FAULT LOW PRIORITY SEE AD AMO-AFR' and sent to the respective service center connected. After the avalanche report has been sent, FAMAFR is deactivated.

•

FSUPV (Supervision time for maximum number of fault reports)
A certain maximum number of fault reports is allowed within the specified supervision time so that the service center will not be flooded with fault reports. The supervision time must be specified in minutes (0 ... 99).

•

SETUPLT (Connection Setup Limit)
This is the fault memory occupancy level starting at which an attempt is made to set up a connection to the service center connected in order to transfer the low-priority fault reports that have accumulated in the meantime. Limit values from 1% ... 90% may be specified.

•

TRSTART (Start of Stored Fault Report Transmission to Network Control Center)
Defines the time of day (0 ... 23 hours, 0 ... 59 minutes) at which the accumulated low-priority fault reports must be transmitted, regardless of the fault memory occupancy level.

•

PERIOD
Defines the number of days (0 ... 99) after which the recently accumulated low-priority fault reports must be transmitted.

•

RETRLT (Retransmision Limit)
Maximum number of successive attempts (0 ... 9) to transmit the contents of the fault memory if the preceding transmission was bad (within one connection).

•

ACTTIME (ACTIVATIONTIME AFTER SWITCH OFF THROUGH AVALANCHE)
Defines the period in minutes (0.. 60) of automatical activation after automatical switching off by message avalanche. During attitude of 0 min no automatical activation is required.

•

MNEGCALL (Maximum Negative Call Setup)
If value of this parameter is 0, AFR-Task works without counting unsuccessful dial-ups.
If it is other than 0, an internal counter in AFR-Task counts the unsuccessful dial-ups to SC (SIRA, Manager). When the count reaches of the value of MNEGCALL the dial-up to the SC is blocked for 12h. Also the following advisory message will be displayed in this case:
F6524 E8 N0103 NO ACT A1 SM-AM MAINTENANCE
06-03-24 11:15:59
ALARM CLASS: CENTRAL: 029

FORMAT: 33
WARNING BY AFR TASK: MAXIMUM OF UNSUCCESSFULLY DIAL UP IS REACHED
SENDING TO SC IS BLOCKED FOR 12 HOURS (AFR2)

Parameter list for the fault pair list (PAR=TAB)

•

FNUM (F-number of a fault action start)
A fault number (5 characters, alphanumeric) is entered under FNUM.

•

FACTION (Start of fault action)
More specific details of the cause of the fault are given under FACTION. Together with FNUM, it characterizes the start of a fault.

•

ENUM (F-number of a fault action end)
The fault number (5 characters, alphanumeric) of the end of fault report is entered under ENUM.

•

EACTION (End of fault action)
The cause of the fault which has come to an end is entered under GACTION. Together with ENUM, it characterizes the end of a fault.

•

COMP (Number of following lines to be compared)
This parameter specifies the number of following lines (0 ... 5) containing module information, which are definitive for comparing the start of fault and end of fault report.

•

FSUPV (Supervision time for fault pair alarm)
A start of fault report is preserved in the fault memory for at least this period before it is transmitted. If the end of fault report is received before start of fault is reported (comparison with F-number, action and following lines), this pair will be deleted.
At the end of the supervision time, the fault report is transmitted according to its priority.
The supervision time must be specified in minutes (0 ... 99).
Single end of fault reports are also transmitted according to priority.
