Endress+Hauser Proline Promass 83 - Alarm Detection and Processing; Selecting the Operating Mode

3.2.2 Selecting the operating mode
The operating mode is configured via the MODE_BLK parameter group. The Transducer Blocks
support the following operating modes:
• AUTO (automatic mode)
• OOS (out of service)
!
Note!
• The block status OOS is also shown via the parameter BLOCK_ERR. In operating mode OOS, if
write protection is not enabled and the release code is entered, you can access all the write
parameters without restriction.
• The following applies for the "Flow" and "Totalizer" Transducer Blocks: In the "OOS" operating
mode, the process variables are updated but the status of the output value OUT (AI Block)
changes to "BAD".
• If problems occur during the configuration of the function blocks → See Operating Instructions
Proline Promass 83 FOUNDATION Fieldbus (BA065D), "Troubleshooting" section.
3.2.3 Alarm detection and processing
The Transducer Blocks do not generate any process alarms. The status of the process variables is
evaluated in the subsequent Analog Input function blocks. If the Analog Input function block does
not receive an input value that can be evaluated from the Transducer Blocks, then a process alarm
is generated. This process alarm is displayed in the BLOCK_ERR parameter of the Analog Input
function block (BLOCK_ERR = Input Failure).
The parameter BLOCK_ERR of the "Diagnosis" Transducer Block displays the device error that
produced the input value that could not be evaluated and thus triggered the process alarm in the
Analog Input function block.
In addition, the active device error is displayed via the "Diagnosis" Transducer Block in the
"Diag. - Act.Sys.Condition" parameter ( → Page 131).
