Hi,

at ANKA we have implemented filtering, which filters alarms regarding

the operation mode. When machine is in shutdown or maintenance, most of

alarms are suppressed, before they reach CSS BEAST.

All our alarms are feed into our intermediate alarm server, which

decided if they should go further to BEAST or be suppressed or be

somehow otherwise processed. For example have summary alarm PV, which

sums alarms from whole subtree.

Our intermediate alarm server is based on JCA and looks like bunch of

plain PV channels which are used by BEAST. No changes were made to

BEAST, everything is in configuration.

Enable feature of BEAST I see more like permanent switch, if you want to

disable misbehaving alarm source.

Hope this helps,

Igor

Hi

We are currently using BEAST. There is the ability to put alarm system in Maintenance mode. But it puts the whole entire system in Maintenance mode. We would like to be able to put an Area or a System in maintenance mode.

I’m wondering if there is any plan to implement such feature. Or would anyone else find this feature useful?

We have started investigating this implementation. Essentially the ENABLED_IND database field should be move to ALARM_TREE table from PV table, and isEnable() should be a base class method.

Thanks,
