Overview
The Global Settings properties encompass broad configurations for alarm management. This includes database settings for logging alarm events, determining behaviors upon system startup, and specific alarm handling parameters. Additionally, these properties offer robust audit trail capabilities, ensuring comprehensive tracking of various system events, user activities, and operational adjustments.
In this section, we can perform various generic configurations for the Alarm module, such as selecting the database type and its lifespan, enabling or disabling advanced options, and making certain customizations to the AuditTrail.
Previously called as AlarmHistorian, these options allow to select the Database where the data will be logged, as well as lifetime to the data log. To setup the Database, left click on the gear icon.
The Alarm Logging Database manages where and how alarms are logged. Users can choose the database type (the default is SQL Lite) define connection parameters, and configure the life span of stored alarm logs.

Connection | Connection string for database connection. |
Life Time | Duration data remains in the database (in days). |
In a manufacturing environment, it is frequently imperative to establish alarm configurations that initiate monitoring only once the system is fully operational. This is particularly relevant for machines that require a certain amount of time to power up and attain operational parameters, as is the case with furnaces and motors. These machines might take minutes to achieve the desired speed or temperature within the process. In such a scenario, the operational deployment of the Alarm Module could potentially result in the inadvertent triggering of multiple alarms.
To align with this context, certain adjustments become essential to prevent such undesired occurrences.
Alarm Handling | |
Initial disable time on Startup | Initial period alarms are disabled upon startup. |
Ignore Alarms During TimeDeadband | Option to ignore Alarms during TimeDeadband |
Enable Limits by Shift | Toggle to set limits based on work shifts. |
Log User Full Name | Option to log the complete name of the user. |
The Audit Trail setting allows users to enable or disable system auditing. When active, users can select which actions, such as user logons, system warnings, or tag changes, are recorded, ensuring transparency and traceability. See Audit Trail for more information.
