Understand “No Diagnostic Support” in SIMATIC PDM LifeList
In SIMATIC PDM LifeList, “no diagnostic support” is a diagnostic result, not by itself proof that HART communication failed. Siemens' PDM V8.2 help describes the result as a field device that does not support additional diagnostic information. The reported version is V6.5, so verify that status meaning and the transmitter EDD against the installed release before diagnosing the separate failure to open device configuration.

Interpret the Lifelist result
The Siemens PDM V8.2 help lists a LifeList result named “no diagnostic support.” It also describes “No diagnostic check” as no known functional restriction and says the field device does not support additional diagnostic information. This is a diagnostic-capability result, not by itself proof that HART communication failed.
Separate diagnostics from configuration access
The report says double-clicking a HART level transmitter shows this status and configuration no longer opens. LifeList scanning/diagnostics and launching the PDM device configuration are separate operations. Verify that the device is identified, the correct EDD is installed and assigned, and the exact transmitter model is supported by the installed catalog.
Check the HART path
The reported interface is HART modem USB 7MF4997-1DB. Confirm the instrument model, loop wiring, power and modem connection against the respective instrument and modem instructions. Do not infer a wiring fault solely from “no diagnostic support,” or assume the online parameter path is healthy if identification/configuration also fails.
Verification
Repeat the scan, compare device identification with the EDD assignment, and confirm whether PDM can open the configuration via the intended HART path. A no-diagnostic-support icon may remain if the device does not provide supported additional diagnostics.
Limitations and Operational Precautions
The opened Siemens help is PDM V8.2, while the ticket names LifeList V6.5 on Windows 7. Exact V6.5 wording, transmitter model, EDD/license and screenshot are unavailable. Follow the installed release's help and the device manual before changing live transmitter parameters.
Engineer FAQ
Is “No diagnostic support” an error code? The manual presents it as a diagnostic result for a device without additional diagnostic support.
Does that explain why device configuration will not open? Not necessarily; EDD support and HART access require separate checks.
