Cause: Output signal is still valid. A limited function has not been detected, but wear reserve is anticipated within the next
few weeks.
Measure: Maintenance of device should be planned.
Function test 2 2 Manual opera‐
tion
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 2 Simulation
mode
5
Cause: Output signal temporarily does not represent the process, because the output is based on a simulation.
Measure: Simulation mode over HMI or disable the engineering system or restart device.
Failure 1 1 Out of service 6
Cause: Output signal does not represent process value. Device mode is set to "Out of service".
Measure: Disable "Out of service" and enable normal operation.
Failure 1 1

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.
