No functional restriction has been diagnosed for the field device, service
is requested. Additional diagnostics information is available.
Manual mode
There is a communication connection with the field device. The device is
in manual mode.
Simulation mode
There is a communication connection with the field device. The device is
in manual mode.
For example, the device is in manual mode "Out of service".
Out of service
There is a communication connection with the field device. The device is
in manual mode.
For example, the device is in manual mode "Out of service".
Configuration error
Field device fault due to a parameter or configuration error in the hard‐
ware components. A maintenance alarm is triggered automatically.
Configuration warning
Field device warning due to invalid parameters for which substitute val‐
ues are used. A maintenance request is triggered automatically.
Configuration changed
The parameters set for the device do not match the parameter data
saved in the project. Communication with the device is possible to carry
out a value comparison or to change parameter settings.
Unknown diagnostics status
Unknown field device status due to invalid parameters for which substi‐
tute values are used. A maintenance request is triggered automatically.
Process value alarm
At least one process value has exceeded or fallen below a hardware
interrupt limit whose parameters were assigned in the device. Commu‐
nication with the device is possible.
Process value warning
At least one process value has exceeded or fallen below a process
warning limit whose parameters were assigned in the device. Commu‐
nication with the device is possible.
Process value tolerance
At least one process value has exceeded or fallen below a process
tolerance limit whose parameters were assigned in the device. Commu‐
nication with the device is possible.
