6 Status classification and condensed state
All status alarms are classified in the positioner to report an error that has occurred. The status
classification can be changed over the following
FOUNDATION™ fieldbus parameters in the
AO Transducer Block (AO TRD):
4
ERROR_OPTION_INIT_FAILURE (36):
Masking of the initialization error
4
ERROR_OPTION_OPERATION_FAILURE (37):
Masking of the operational error
4
ERROR_OPTION_HW_FAILURE (38):
Masking of the hardware error
4
ERROR_OPTION_DATA_FAILURE (39):
Masking of the data error
4
ERROR_OPTION_ENH_DIAGNOSTIC (40 bis 44):
Masking of the status and fault alarms generated by the diagnostics
To provide a better overview, the classified alarms are summarized in a condensed state
(CONDENSED_STATE (59) in the RES Block). Besides the CONDENSED_STATE parameter, the
condensed state can be issued to the discrete output OUT_D of the DI Function Blocks (DI1 +
DI2).
Possible condensed states include:
0OK
1 Maintenance
required
The positioner still performs its control task (with restrictions). A maintenance re-
quirement or above average wear has been determined. The wear tolerance will
soon be exhausted or is reducing at a faster rate than expected. Maintenance is
necessary in the medium term.
2 Maintenance
demanded
The positioner still performs its control task (with restrictions). A maintenance de-
mand or above average wear has been determined. The wear tolerance will soon
be exhausted or is reducing at a faster rate than expected. Maintenance is neces-
sary in the short term.
3 Maintenance
alarm
The positioner cannot perform its control task due to a functional fault in the device
or in one of its peripherals or an initialization has not yet been successfully com-
pleted.
7 Function check Test or calibration procedures are being performed. The positioner is temporarily
unable to perform its control task until this procedure is completed.
In addition to the condensed state, the block error alarms (BLOCK_ERR) from the Resource Block
and Transducer Block can also be assigned to the events.
In this case, the individual alarms must be classified in the ERROR_OPTION_… (Index 36 to 44)
