Diagnostic Events Reported By Alarms - GE Baker Hughes Masoneilan SVI FF Installation And Operation Manual

Diagnostic Events Reported by Alarms

In hosts that support Foundation Fieldbus alarms, the standard block alarm (provided through
BLOCK_ALM parameter) is reported when a failure is detected in the device. The block alarm is
used for all configuration, hardware, connection failure or system problems in the block and in
this case also reports the diagnostic events detected by the positioner. The first alert to
become active sets the Active status in the Status attribute. As soon as the Unreported status
is cleared by the alert reporting task, another block alert may be reported without clearing the
Active status, if the sub code has changed.
Figure 93 illustrates how BLOCK_ALM is generated when a problem is detected in the SVI FF
positioner.

If the failures, detected in the positioner, are mapped to the Resource block, the standard for
resource block alarm summary (ALARM_SUM) parameter can be used to enable or disable the
alarm notifications.
