Alarm Event Recorder; Some Basic Checks - ABB ETL600 Instruction Manual

ABB Switzerland Ltd
the alarms coming back – if any – written to files (one file per day) with
date- and timestamps supplied by the PC. If a device cannot be
reached, a communication error will be recorded for that device.
All alarms except detail alarms are collected via alarm polling. These
are:
•
Alarms and warnings referring to the P4LT-board.
•
For each configured O4LE-board:
One HW alarm and one warning.
•
For each configured G4AI-board:
Two HW alarms, two interface alarms and one warning.
Detail alarms are accessible only via equipment status upload.
Note:
9.3.10.

Alarm event recorder

All alarms/warnings except detail alarms are recorded as events in
non-volatile memory on P4LT. An alarm event is a snapshot of the
ETL600 alarm state together with a date/time stamp. The recorded
events can be uploaded to the PC and viewed with the help of the
HMI600 program.
The event recorder is described in section 3.7 .

Some basic checks

It is advisable to do the following basic checks before energizing a
PLC link. This minimises the chances of a fault in the first place and
also reduces the time of troubleshooting in case there is any.
•
It is essential to check the communication line (as described in
Chapter 7 ) especially in the frequency band in which the PLC link
will be used.
•
In case modems are used to access the P4LT, it essential to first
check the communications over modems before really trying to
access the equipment. Often the faults are found in wrong settings
of the modem.
•
Ensure that the coaxial cable is properly connected to the
equipment. Check whether the supply voltage to be applied to the
equipment is correct.
•
Ensure that all the modules are properly inserted in their correct
slots.

A mixed alarm polling operation mode with ETL500
and ETL600 devices - both polled by the HMI600
alarm polling facility - is possible.
Nevertheless the low level alarm messages of the
ETL500 may differ from those of the ETL600 system
(please check the corresponding Instruction Manual
Chapter 9 for explanation and corrective actions).
