-----+===== New alerts configuration =====
  
 +In WebHMI there is the concept of an alert. An alert is a state of the system that requires human attention. WebHMI signals on all alerts visually (red status bar on the dashboards) and an audible signal about unqualified accidents. The alerts are kept in a special alerts log. 
 +
 +Starting from 3.6 fw version, __a new alert setup__ has beed implemented. For versions below 3.6 please refer to the next section. ​
 +
 +When some alert triggers there will be pop-up window, like this - 
 +
 +{{ ::​descent_alert_msg2.png?​direct&​400 |}}
 +
 +There will be the alert title, group (if it belongs to a group), start time, duration, acknowledge status and the link to details. ​
 +In the new alerts there is a number of improvements:​
 +  *more complex conditions for each alert. ​
 +  *richer alert description with insructions ​ (extended text format, pictures)
 +  *operator can add comments after alert has been triggered
 +  *templates - for identical devices with the same alerts conditions, you can setup only one template ​
 +
 +The alert setup link is here:
 +
 +{{ ::​alerts_link.png?​direct&​400 |}}
 +
 +The example of an alert list:
 +
 +{{ ::​new_alerts_list_commented.png?​direct&​400 |}}
 +
 +Here:
 +  -is the button to create an **alert object**
 +  -is the button to create an **alert group**
 +  -is the list of non-grouped alerts
 +  -is the **category** name for organizing the list. There are 2 groups in the example provided. ​
 +  -it is a list of **grouped alerts**. The titles in bold text indicate group title. Only a group can be a template for another group of alerts. The template column tells if the group is a template or templates'​ descendant. ​
 +  -is a list of **templates'​ descendants**. For descent alert groups you can tell the system substitution rules for the registers, in the same way as for dashboard templates.
 +
 +In the __Basic__ edit alert tab you set title, template, category and level (Info, Warning, Alert), wether to allow acknoledge and sound signal.
 +
 +{{ ::​alert-edit-basic-tab.png?​direct&​400 |}}
 +
 +In the __Condition__ tab, you define the condition which will trigger the alert. It can be specific bit of a register or its value (=, ≠, <, >, [a, b]((in range from a to b))). The multiple conditions are combined only with AND operator. So for OR operation or more complex conditions you can use Lua scripts. ​
 +
 +{{ ::​alert-edit-contition.png?​direct&​400 |}}
 +
 +In the __Information__ tab, there is a text editor with formatting options to create messages including one optional picture. This message will be shown if an operator press Details... link in the alert pop-up dialog. ​
 +
 +{{ ::​alert-edit-information.png?​direct&​400 |}}
 +
 +Information page in this case could be like this:
 +
 +{{ :​alerts.png?​direct&​400 |}}
 +
 +All alerts are stored in their log, which can be accessed from side bar or context menu link.The following filters are available for convinient looking-through:​
 +  * Level - info, warning, alert
 +  * title - with find sub-string
 +  * group
 +  * status - active / fixed, acknoledged and not acknowledged
 +Every column has a sorting action and an omni-search box is provided as well to search in all alerts. ​
 +
 +{{ ::​new_alert_log_view.png?​direct&​400 |}}
