7 Error Handling
Errors are indicated by the error relay. Error messages are dis-
played via the fieldbus control software and/or the process control
system and in the parameter XD_ERROR in the function block
TRANSDUCER.
7.1 Device Response in Case of Error
Use the function block RESOURCE and the parameters
ERROR_LOG_ENTRY and ERROR_LOG_DATA for query (see section
5.10 on page 7–699). You find the parameter Quality in the record
PRIMARY_VALUE in LE_LEVEL.
1 The device first switches to the safe state and then has to be reset by turning off/on the power supply so that
the measurement can be started again.
2) Error 14 always leads to error 13! The error log shows both errors.
