Alarm Generation
When the FVP110 detects an abnormality in the device using the self-diagnostic function,
a device alarm is issued from the resource or transducer block. An abnormality in a
function block or in a process value is issued from the corresponding block as a block
error or process alarm.
A FVP110 can report the following alarms and events.
Analog alerts A type of alarm generated when a process value or a deviation
value exceeds a specified limit in the following blocks: PID block :
HI, HI_HI, LO, LO_LO, DV_HI, DV_LO
Discrete alerts A type of alarm generated when an abnormal status is detected:
❑ Resource block - a discrete alert is generated as a block
alarm or write-error alarm.
❑ DI block - a discrete alert is generated as a block alarm or
DISC alarm.
❑ Transducer, AO and PID block, a discrete alert is only
generated as a block alarm.
Update alerts Generated when a change is made to the settings of certain
parameters.
Table 28 shows the elements composing an alert object.
