ATTENTION
With R400, you can disable or enable individual block errors. This is applicable for
Function blocks, Transducer blocks, and Resource blocks and only when block alarm
is enabled in Alarms tab.
Following are some of the considerations for disabling individual block errors.
For the blocks such as AI block configured in Control Modules, when an inactive
block error is disabled and if the block error turns active, the Alarm Display will not
display the alarm and the Event Summary will not display the alarm event. For the
devices only blocks such as, Resource or Transducer blocks, block error alarm
appearance in the Alarm Display or System Status Display is affected.
Regardless of disabling, the individual block error status is displayed on the block’s
Maintenance tab.
When an active block error is disabled, the Alarm Display or System Status
Display alarm returns to normal, and Event Summary displays the alarm action
as OK.
In the Alarm Display or System Status Display, when you acknowledge block
error alarms that have returned to normal, the alarms disappear and Event
Summary displays the acknowledged alarms.
When the disable is removed for an active block error, the Alarm Display or
System Status Display displays the alarm as active and Event Summary
receives the event for that particular alarm.
