  • CitectSCADA v7.10 spk 2 
Summary:

HF710SP245563 for CitectSCADA version 7.10 service pack 2.

This Hotfix provides a fix for the following bugs:


Bug 44100 - Acknowledged, cleared alarms active on redundant server after startup and synchronisation

During synchronization of the alarm server, dynamically set alarm properties were not being set from
synchronisation data.
This means that when the active alarm server is shut down the alarm properties on the redundant alarm
server can be different and alarms may re-trigger or not trigger at all.


Bug 44505 - The file 'AlmIndexSave.dat' was corrupt or invalid after deleting and adding alarms

Alarm index file corruption can be caused by adding and removing alarms from the project and then
starting Citect. The problem is related to the deleted alarm ids being re-used by the newly created
alarms.


Bug 43547 - Acknowledged ON alarms need to be reacknowledeged after a restart

The IOServer code has been changed so that alarm values have an initial quality of 
GENERIC_UPDATE_INPROGRESS rather than GENERIC_NOERROR.
This means that all tag values will not return good quality data by default.


Bug 44678 - Alarm High value property is not being transmitted to the redundant server

When alarm properties are dynamically changed, the changes are not transmitted to the redundant server.
This means that when the active alarm server is shut down the alarm properties on the redundant alarm
server can be different and alarms may re-trigger or not trigger at all.


Bug 44156 - Clients that connect to the primary alarm server while it is resyncing do not get alarm data

The primary alarm server listener is now not opened until after it has finished re-syncing. 
This means that clients connect to the standby alarm server during this period.
