Alarm and Events
Alarm Hiding
Alarm hiding should be configured in the provider system. Alarms hidden in the
provider will show up in a hidden alarm list in the subscriber system. It is however
not possible to show the corresponding hiding rule in the subscriber for a hidden
alarm, since the hiding rule only exists in the provider.
Alarm Shelving
Alarm shelving configuration is done in library structure in both provider and
subscriber systems. For a consistency behavior it is recommended that shelving
configuration conforms for provider and subscriber.
Audible Alarms/Global Silence
Global silence is a function which allows an operator on one workplace to silence an
alarm on all workplaces. If global silence is used with Multisystem Integration, a
silence operation made in the provider will also affect the subscriber and vice versa.
Feature Pack Functionality______________________________________________________________________
Point of Control Support
This section applies to the System 800xA 5.1 Feature Pack release only.
Point of Control is a concept that allows division of the plant into sections. The
operator controlling a section is called the Responsible User. The Responsible User
has all access rights for the section. A typical scenario is that only the Responsible
User will be able to control the process in this section.
Using Point of Control with Multisystem Integration, the responsibility can be taken
locally on the provider system, and remotely on the subscriber system. For more
information on the Point of Control function, refer to Point of Control section in
System 800xA Administration and Security (3BSE037410*).
The responsibility can be transferred between the provider systems located within
the plant area and also between the provider system and the subscriber system.
