800xA alarm acknowledge
At our plant we have three different places with 800xA operator-stations.
Each place has it´s own user-account.
Is there any possibility for multiple alarm acknowledge?
Alarm xy is acknowledged by user "A" at place "1", at the other two places the alarm is still active.
Some parts of the machine may be controlled by multiple users, but every user has to notice an alarm.
Hope you know what i mean :)
i think this setting isn´t the right one for my kind of problem.
When checking the "dual ack" this only means that an alarm on both server in a redundant server pair gets ack requests, or?
USER1 ALARM xy !!! -> ACK by USER1
(alarm not in alarm line but in alarm list)
USER2 ALARM xy !!! alarm still active till ACK(alarm in alarm line and alarm list)
USER3 ALARM xy !!! alarm still active till ACK
(alarm in alarm line and alarm list)
--> ALARM xy !!! -> ACK by USER1,2&3 --> alarm acknowledged
(alarm not in alarm line and not in alarm list)
Sounds like a nice feature to have - unfortunately, I believe you must pursue your regional ABB sales representative to have this filed as an "enhancement request".
A workaround could be to have the code in the PLC to raise an alarm for each operator that must acknowledge the deviation. Workplaces can be made to filter alarm per location or "Responsibility", i.e the alarm can actually be made to "follow" a particular user.
