Failure 1 Maintenance alarm 1
Cause: Output signal invalid due to fault in the field device or in the peripherals.
Measure: Maintenance is required immediately.
Maintenance
required
4 Maintenance demanded
2
Cause:Output signal is still valid, but wear reserve is almost exhausted and/or a function will be limited soon.
Measure:Maintenance is strongly recommended as soon as possible.
Maintenance
required
4 Maintenance required 3
Cause: The output
signal is still valid. No functional restrictions have been determined but the wear reservice will most likely
be exhausted in the next few weeks.
Measure: Maintenance of device should be planned.
Function test 2 Manual operation 4
Cause: Output signal temporarily invalid (e.g. frozen) due to work being performed on the device.
Measure: Manual mode over HMI or disable the engineering system.
Function test 2 Simulation mode 5
Cause: The output signal does temporarily not reflect the process because the output is based on a simulation value.
Measure: Simulation mode over HMI or disable the engineering system or restart device.
Failure 1 Out of service 6
Cause: The output signal does not represent the process value. The device mode is set to "Out of service".
Measure: Disable "Out of service" and enable normal operation.
Failure 1
(red)
Configuration error 7
Cause: Output signal invalid due to parameter setting, connection error or configuration error in the HW.
Measure: Check hardware configuration of the device over HMI or engineering system.
