That phrase is unusual for Siemens software. Quality updates come from:
| Attribute | Details |
|-----------|----------|
| File name | SIMATIC‑S7‑ProjX‑V55‑SP13‑UPD1.EXE |
| Vendor | Siemens AG (Digital Industries – SIMATIC S7 family) |
| Typical location | Distributed via Siemens Industry Online Support (SIOS) or the “Update Center” for S7‑300, S7‑400, S7‑1200, and S7‑1500 PLC hardware. |
| Purpose | A self‑extracting executable that installs the “Extra Quality” (sometimes called “Extended Quality”) firmware/diagnostic package for the S7‑ProJX V5.5 hardware platform, Service Pack 13 (SP13). |
| Versioning | The “V55” part denotes the hardware series (ProJX V5.5). “SP13” is the Service Pack level. “UPD1” signals the first update release for that service pack. |
In short, the file is a firmware upgrade that adds new features, bug‑fixes, and quality‑of‑service improvements to Siemens’ ProJX PLCs. simatics7fprojxv55sp13upd1exe extra quality
Any .exe with this naming pattern is not digitally signed by Siemens. Running it could inject ransomware, steal credentials, or backdoor your engineering workstation.
Tip: Always keep the original firmware backup file (usually a
.s7parchive) in your engineering archive. It makes rollback painless if any unexpected behavior appears. That phrase is unusual for Siemens software

| Symptom | Likely Cause | Fix |
|---------|--------------|-----|
| PLC stays in “STOP” after reboot | Firmware flash error or checksum mismatch | Re‑run the installer, ensuring a stable power supply. If it persists, use the Firmware Recovery Tool from Siemens to force a rollback. |
| TIA Portal cannot read the firmware version | Wrong communication driver (e.g., using an outdated PROFINET driver) | Update the PROFINET driver on the engineering PC or use the “Legacy” driver for older PLCs. |
| Unexpected watchdog resets after update | A new diagnostic routine is more sensitive to short‑circuit loops in user code | Review any user‑written cyclic tasks; add a brief WAIT or increase the watchdog timeout via the System → Watchdog settings. |
| Checksum error during flash | Corrupt download (e.g., interrupted transfer) | Re‑download the EXE from Siemens, verify the file size, and repeat the upgrade. |
| Device shows “Extra Quality – Not Certified” | The project’s safety integrity level (SIL) was locked to the previous firmware | Update the Safety Certificate in the project’s safety configuration or request a new certification from Siemens. |
