NOTE: Both views can be configured separately.
Alarm Handling When the controller is connected to ARENA, alarms are received automatically as
soon as ARENA is installed or the remote site has been configured correctly using
ARENA's site configuration.
NOTES: Dial-up sites will automatically connect to the supervisor PC in case of a
critical alarm. Alarms from LAN sites can only be received if the LAN site is
connected explicitly. Make sure you connect to a LAN site once it has been
successfully created. After exiting and restarting ARENA, previously
connected LAN sites will be automatically reconnected.
The PANTHER / TIGER controller will always send out critical alarms as
soon as they occur. After alarms have been sent, a "blocking time" of 24
hours becomes active for uncritical alarms. During the blocking time, no
uncritical alarms are sent out. However, if there’s a danger of losing alarms
(because the controller’s alarm buffer is 80 % full), the uncritical alarm will
be sent. Also, if a connection is established during the blocking time (e.g.
as a result of a critical alarm), the pending uncritical alarms are sent.
PANTHER / TIGER controllers try to send a critical alarm to ARENA
directly after it occurred. If ARENA does not respond, the controller repeats
the connection attempt each 5 minutes for ½ hour. After that, it repeats the
attempt to reach ARENA each 4 hours, for 3 days. If ARENA does not
respond for 3 days, the controller stops its attempt to reach ARENA. It will
restart the attempt only after ARENA successfully dials into the site.
Acknowledging Alarms ARENA allows the operator to document that he has seen an alarm. This is called
“acknowledgement”. Acknowledgements can be made by Email (responding to a
forwarded Email), or manually. The person who has made the acknowledgement is
stored with the alarm and displayed in the alarm history. In case of Email
acknowledgements, the sender’s Email address is an indication for the person who
has made the acknowledgement.
To acknowledge an alarm that has been forwarded by Email, just reply to the alarm
Email (i.e. send it back to ARENA). ARENA will receive the Email via POP3, and will
show the replier´s Email address in the acknowledged by field. If an
acknowledgement has successfully been processed by ARENA, it will be deleted
from the mailbox.
To acknowledge alarms manually, click the alarm(s) in the alarm list and click the
Acknowledge button on the Global Alarm List pane.
