Cleaning - Siemens SITRANS P DS III Operating Instructions Manual

Technical developments enable advanced functions to be implemented in the firmware of the
measuring cell or application electronics. Further technical developments are indicated by
modified firmware statuses (FW). The firmware status does not affect whether the modules
can be replaced. However, the scope of functions is limited to the function of existing
components.
If a combination of certain firmware versions of measuring cell and application electronics is
not possible for technical reasons, the device will identify this problem and go into "Fault
current" mode. This information is provided via the HART interface.
