Investigate CEMAT Check Tool Faults 69 and 70 on PCS7AN Channel Drivers
In the reported CEMAT Check Tool V8.2 project, Fault 69 is described as “No connection on PV_In input” and Fault 70 as “No connection on PV_Out input.” Treat these as connection-check findings: inspect the exact channel-driver block instance and its PV_In/PV_Out interconnections in CFC, then rerun the check after correcting any missing or mismatched connection. The report does not provide the check-tool manual or project details, so the codes' official definitions and the specific cause remain unverified.

What the reported faults identify
The report concerns CEMAT Check Tool V8.2 and the channel-driver blocks Pcs7AnIn, Pcs7AnOu, Pcs7DiIn and Pcs7DiOu. It reports Fault 69 as no connection on PV_In and Fault 70 as no connection on PV_Out; a reply says these codes are generated when I/O links are not properly connected. These are source-reported interpretations, not independently verified definitions in the references available for this article.
Because the follow-up says the blocks appear correctly connected, the remaining task is to identify what the checker evaluates for the specific block type and instance. Visual inspection alone may not resolve a mismatch, hidden chart difference, wrong pin, or library-specific requirement; the exact rule must be confirmed against the CEMAT V8.2 Check Tool documentation.
Focused CFC investigation
- Record each flagged chart, block instance, block type, and fault number from the CEMAT Check Tool output.
- Open the flagged CFC chart and inspect the exact
PV_InandPV_Outpins named in the diagnostic. Confirm the expected source and destination pins for that specific driver type using its applicable CEMAT/PCS 7 block documentation. - Check whether the displayed connection belongs to the flagged instance and whether the value is wired through the intended CFC interconnection. Do not assume that a similarly named pin or a different driver instance satisfies the checker.
- Compare a flagged instance with an equivalent known-good instance only after confirming the hardware channel and block variant are equivalent.
- Correct only a confirmed connection/configuration discrepancy under the project's change-control process, then rerun the Check Tool and inspect its complete output.
These are cautious diagnostic actions, not a confirmed CEMAT V8.2 repair procedure. The exact block requirements and tool behavior need the applicable manual.
Separate input and output checks
Investigate PV_In and PV_Out separately. Fault 69 reportedly points to the driver input PV_In; Fault 70 reportedly points to output PV_Out. The expected direction and data structure may differ by channel block family and version. Do not create a connection solely to suppress the checker: determine which signal is intended and confirm that its source, destination, and data type match the installed block documentation.
Verification
After resolving a documented cause, rerun CEMAT Check Tool V8.2 against the same project scope. Confirm the corresponding Fault 69 or 70 finding is absent and review all other findings. Independently verify the channel's expected value and status path in the project's approved test or commissioning process. A cleared static check alone does not prove correct physical I/O mapping or runtime signal quality.
Limitations and Operational Precautions
The source does not include the exact checker output, CFC charts, block versions, module configuration, or the CEMAT V8.2 Check Tool definition for Faults 69 and 70. Siemens' official CEMAT V8.2 engineering manual search result was found, but the web reader could not open the large PDF; therefore its exact fault definitions could not be verified from the document. Do not treat the reported messages as a universal definition across CEMAT versions. Avoid speculative rewiring or downloading to a live system; use approved project backups, review, test and rollback procedures.
Engineer FAQ
What does Fault 69 mean in this report? The report labels it “No connection on PV_In input.” This wording is taken from the source and has not been independently confirmed against the CEMAT V8.2 checker manual.
What does Fault 70 mean in this report? The report labels it “No connection on PV_Out input.” Confirm the exact official definition and the affected block variant before changing the chart.
What if the CFC connection looks correct? Match the diagnostic to the exact chart and block instance, inspect the specific named pin and confirm the checker's expected connection rule from the applicable manual.
Should a connection be added just to clear the fault? No. Establish the intended signal path and verify source, destination, and type before making a change.
Does a cleared checker fault prove the I/O works? No. Verify the signal and quality/status path using the project's approved runtime or commissioning checks.
Technical References
No supporting manufacturer page could be opened to verify the CEMAT Check Tool V8.2 Fault 69 and 70 definitions. The Siemens CEMAT V8.2 Engineering Manual was located at https://cache.industry.siemens.com/dl/files/911/109745911/att_913675/v1/Cem_V82_Engineering_000_en.pdf, but the web reader returned a content-length error while opening it; it is therefore not cited as a verified technical reference.
