To provide a better overview, the classified alarms are summarized in a condensed state
(CONDENSED_STATE (59) in RES Block). Besides the CONDENSED_STATE parameter, the
condensed state can be issued to the discrete output OUT_D of the DI Function Blocks.
Possible states of the condensed state include:
0ok
1 Maintenance

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.

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 status, 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) parameter with another status for block errors.
The following classifications are possible:
4
No message
4
Maintenance soon
4
Maintenance now
The block error (BLOCK_ERR) results from the summary of classified alarms that are active.
