PV represents Primary Values and SV represents Secondary Value.

The Alert Notification Mechanism is used to inform a master device of an error. In addition, Alert Notifications

provide some information on process conditions and events and are automatically sent to a master device. So

whenever an alarm or an error condition enables an Alert Notification, the alert is received at the master device as

one of four reported states: Acknowledged, Unacknowledged, Reported, or Unreported.

Alarm Summary

Whenever an alarm is enabled and the alarm condition occurs, notification at the Master device is initiated by using

an Alert Notification and setting the relevant bit in the Current Alarms field. The Unacknowledged field reflects if the

alarm has been recognized at the Master device. The Unreported field reflects if the alarm was linked to a system at

which each alarm event has to be reported.

Alarm Type Description

Discrete Alarm

Supported only by the Resource Block. When the Hardware (Switch 1) and/or

Software write locks have been set.

HI_HI_Alarm

Supported by AI. Notified when the OUT value goes above the HI_HI_LIM value

and when the OUT value drops back down below the HI_HI_LIM value. Alarm

state and time stamp only recorded when HI_HI_PRI is non-zero.

HI_Alarm

Supported by AI. Notified when the OUT value goes above the HI_LIM value and

when the OUT value drops back down below the HI_LIM value. Alarm state and

time stamp only recorded when HI_PRI is non-zero.

LO_LO_Alarm

Supported by AI. Notified when the OUT value goes below the LO_LO_LIM value

and when the OUT value rises back over the LO_LO_LIM value. Alarm state and

time stamp only recorded when LO_LO_PRI is non-zero.

LO_Alarm

Supported by AI. Notified when the OUT value goes below the LO_LIM value and

when the OUT value rises back over the LO_LIM value. Alarm state and time

stamp only recorded when LO_PRI is non-zero.

Block Alarm

Supported by RB, TB and AI. Notify when a Block Error occurrence is encountered

for the relating block. See Block Error.

Limit alarm bits are set to 1 or 0. A ‘1’ represents an active alarm and a ‘0’ represents an inactive alarm in the

Current Alarms field.
