Operating system update: It can be updated through external storage media or configuration PC. Before updating, the automatic backup function must be disabled to avoid data loss.
Automatic backup: can be activated after inserting the system storage card, real-time synchronization of device data, and quick recovery in case of failure.

5. Project implementation and operation
(1) Project transmission and testing
Transmission method: Supports manual/automatic transmission from the configuration PC, or loading projects through external storage media. Automatic transmission is suitable for the testing phase and is recommended to be disabled after debugging is completed.
Operation mode: divided into three modes: offline (communication without controller), online (communication with controller), and transmission (project transmission/data backup), which can be switched through project configuration operation elements.
Test types: offline testing (verifying interface and operation), online testing (verifying communication and functionality), which requires checking screen layout, navigation, input objects, measurement value updates, etc.
(2) Project Operations
Operation mode: Touch screen (sharp objects are prohibited from touching), device keyboard, external USB keyboard/mouse, supporting single touch, function key operation, and numerical input (numbers/alphanumeric).
Core operations: language switching (up to 32 languages), function key operations (global/screen specific functions), direct keys (quick control of PLC I/O bits), information text viewing, project closure, etc.
Numerical input: The on-screen keyboard automatically pops up, supporting range verification and decimal filling. Exceeding the limit will trigger an alarm and reject input.
6. Maintenance and troubleshooting
(1) Daily maintenance
Cleaning: After turning off the power or locking the touch screen, wipe it with a cloth dipped in neutral cleaner. Do not use compressed air or corrosive solvents.
Repair: Only Siemens approved spare parts are allowed. In case of malfunction, contact official technical support and provide information such as equipment model and image version.
Recycling: It must be processed by certified electronic waste recycling companies and comply with local environmental regulations.
(2) Common fault handling
System memory card error: Check if the memory card is compatible (≥ 2GB SIMATIC HMI memory card), replace the faulty memory card.
Communication failure: Verify IP address/bus address uniqueness, cable connection and shielding, controller model compatibility.
Touch screen unresponsive: recalibrate the touch screen and check for physical damage.
7. Core parameters of technical specifications
Display specifications: 16 million color TFT widescreen, resolution of 480 × 272 to 1920 × 1080, backlight life of 30000-8000 hours (varies by model).
Communication performance: PROFINET has a maximum transmission rate of 1000Mbps, PROFIBUS DP has a maximum speed of 12Mbps, and supports secure HMI communication (TIA Portal V17 and above).
Software features: WinCC supports up to 750 images, 6000 discrete alarms, 500 recipes, and supports VBScript extension, data archiving (CSV/RDB/TXT format), and user permission management (up to 50 user groups).
Protection level: IP65 on the front and IP20 on the back, in compliance with IEC 60529 standard.
Key precautions
Strictly follow the requirements for heat dissipation and protection during installation, otherwise it will affect the lifespan of the equipment and the effectiveness of certification.
When used in explosive hazardous areas, it is prohibited to plug and unplug connectors and storage cards with power on, and it is necessary to ensure that the plugs are not loose.
Before transferring the project, it is necessary to confirm that the device firmware is compatible with the WinCC version. Updating the operating system will clear all data, so it is important to backup in advance.
Network configuration should avoid IP address conflicts, and PROFINET device names and computer names should be configured separately.
Touch screen calibration requires the use of a stylus or fingers to avoid damage caused by sharp objects.
