Overview
The Alarms Global Settings properties encompass encompasses broad configurations for alarm management. This includes , including 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.
Configurating Global Settings
The Global Settings interface is composed of three parts, they are:
- Alarm Logging Database
- Alarm Handling
- Audit Trail
See more details on each of them in the sections below.
Alarm Logging Database
The Alarm Logging Database setting manages where and how alarms are logged. Users can choose the database type
, define connection parameters, and configure the life span of stored alarm logs.
See below a table with all available settings for alarm loggings:
Setting |
|---|
Description |
|---|
Database | Database |
The type of database used |
. The default |
option is SQL Lite. |
You can adjust this setting by clicking |
the gear icon. |
Connection |
The connection string for database connection. |
Life Time |
Defines the amount of time the 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
The Alarm Handling setting manages the alarms considering the operational status of the devices. See below a table with all available settings this section:
Setting | Description |
Initial Disable Time on Startup | This setting determines the period during startup when alarms are disabled. It ensures that alarms are not triggered immediately upon startup, allowing the system to stabilize first |
Alarm Handling | Initial disable time on Startup | Initial period alarms are disabled upon startup
. | |
Ignore Alarms During TimeDeadband | |
This option enables the system to ignore | |
alarms during a specified TimeDeadband. | |
Enable | |
LimitsByShift | Allows the user to set different alarm limits based on different work shifts. |
See our Alarms Limits by Shift Example. | |
LogUserFullName | Option to log the complete name of the user. |
Audit Trail
The Audit Trail setting allows users to enable or disable system auditing. When active, users can select which actions, such as user logonslogins, system warnings, or tag changes, are recorded, ensuring transparency and traceability. See Audit Trail for more information.
