13.2.3 Operating panel variants
The following operating panel variants can be parameterised for all operating panels (incl.
SIGMASYS C control and indicating panels):
•
Control center operating panel:
Normally permanently busy, no screen-blanking feature. This operating panel can be
assigned an operating panel with standby function that automatically takes over the re-
sponsibilities of a failed control centre operating panel on an object-specific basis.
•
Local (on-site) operating panel:
Not permanently busy, screen-blanking feature for IMT available, cannot be assigned a
standby operating panel.
•
Infopanel:
Used as a straightforward display terminal without operating function (excluding polling
function) and is also installed in addition to a control centre/on-site operating panel.
Screen-blanking function available. Cannot be assigned a standby operating panel.
•
Standby function for control center operating panels:
For redundancy for a control centre operating panel, the operating and display functions
can be taken over by one or more operating panels if the control centre operating panel
fails. In normal operation, it is not possible to display information or perform operations
at a standby operating panel. The standby function is assigned on an object-specific
and criteria-specific basis. A command must be entered to reassign the responsibility
once the on-site operating panel is put back into operation. The standby function only
becomes active if an object is no longer supported by a control centre operating panel.
Only one standby operating panel may be programmed per object.
If no standby function is programmed, the control center operating panel with the lowest num-
ber takes over the responsibility in the event of operating panel failure.
Parallel operation is possible if multiple control centre/on-site operating panels are parameter-
ised with the same responsibilities: alarm display is updated simultaneously at all responsible
operating panels
(with an internal acoustic alarm) and can be modified at all responsible
operating panels. Modifications to an alarm via a processing operation are displayed at all
operating panels.
Reaction of the operating field keys in the case of multiple control and indicating panel re-
sponsibilities:
Reset:
based on the object or alarm
Acoustic off: based on the event, acoustic VdS alarm device and internal
alarm off
At least one control centre operating panel must be programmed in the system
All detector objects must be assigned at least one control centre operating panel.
