Siemens SIMATIC Panel PC 670 and 870
SIMATIC Panel PC 670 units are industrial PCs with a front display, designed to combine supervision, HMI and data processing directly on the machine. They were very widespread in the early 2000s and remain installed on a great many machines and lines, often with supervisory software that only runs on that hardware.
In the E-Repair catalogue they are the SIMATIC family with the most part numbers: about 1,250 Panel PC 670 (roots 6AV772x and 6AV773x) and some Panel PC 870 (root 6AV771x), the higher-end version.
⚙️ How they are built
- Operator front with colour TFT display (for example 12.1" or 15.1") and, depending on the version, membrane keyboard or touch screen.
- PC unit with processor, memory, disk and industrial interfaces.
- Standard configurations and versions with a remote front, in which the operator panel is separate from the PC unit.
Each part number identifies a precise configuration of display, front, processor, memory and pre-installed software: a replacement always requires the full part number from the rating plate.

⚠️ Typical faults
- worn-out display backlight, with a dark or missing image
- damaged touch screen or membrane keyboard
- hard disks at end of life, with a risk of losing the installed software
- worn power supplies and fans, with sudden shutdowns or overheating
- exhausted backup battery, with loss of settings
Before any intervention it is essential to save a disk image: the supervisory software is often no longer easy to reinstall.

❓ Frequently asked questions
✔️ Can just the display or touch screen be repaired?
Often yes. The E-Repair diagnosis shows whether the fault concerns only the front or also the PC unit.
✔️ Can I replace a Panel PC 670 with a more recent model?
It is possible, but the compatibility of installed software, interfaces and mounting dimensions must be checked. Repairing the original avoids reinstalling the software on new hardware.
✔️ What is needed before shipping?
The full part number from the rating plate, a description of the fault and, if possible, a backup image of the disk.
