Pro face PFXSTM6400WAD human-machine interface

5.2 Protection level

In terms of structural protection, the rear module (electronic part) is IP20, suitable for installation inside the control cabinet, and only protects against solid foreign objects larger than 12.5mm; The display module (front panel) meets IP65F and complies with UL 50/50E standards for Type 1, Type 4X (indoor use only), Type 12, and Type 13. IP65 means completely dust-proof and can withstand low-pressure jet water from any direction. This allows the touch screen to be installed in situations that require regular flushing or the presence of splashing liquids, such as food and beverage production lines, cleaning equipment, etc. It should be noted that the above level can be achieved when the equipment is installed on a sturdy panel and the front protective film is not peeled off. But if exposed to low viscosity cutting oil or vaporized oil environment for a long time, infiltration or plastic front cover deformation may still occur. Therefore, it is recommended to confirm the actual medium compatibility before installation and regularly replace the installation sealing gasket.

5.3 Vibration and Shock

Vibration resistance complies with IEC/EN 61131-2 standard: single amplitude of 3.5mm in the frequency range of 5 to 9Hz; fixed acceleration of 9.8m/s ² in the frequency range of 9 to 150Hz; Perform 10 frequency sweep cycles in each of the X, Y, and Z directions (total time approximately 100 minutes). Impact resistance performance: peak acceleration of 147m/s ², 3 times in each direction. These indicators ensure that the equipment can be installed on devices with mechanical vibrations, such as punching machines, textile machinery, or transport vehicles.

5.4 Electromagnetic compatibility

Electric fast transient/pulse group: IEC 61000-4-4, power port 2kV, signal port 1kV.

Electrostatic discharge immunity: IEC/EN 61000-4-2 Level 3, contact discharge 6kV, air discharge 8kV.

In addition, the product complies with CE, UKCA, and UL certifications and is suitable for Class 1 Division 2 hazardous environments, where flammable gases or vapors are present but not normally present. This has expanded its applications in industries such as petrochemicals and spray painting.

5.5 Other environmental parameters

Dust concentration: ≤ 0.1 mg/m ³ (non-conductive dust).

Pollution level: Level 2 (only non-conductive pollution, occasional temporary condensation).

Corrosive gas: No corrosive gas is required.

Atmospheric pressure (altitude): 800 to 1114hPa (corresponding to altitudes below 2000 meters).

Memory and Data Storage

6.1 Application Memory and Local Storage

When using BLUE engineering software (the next-generation design platform of Pro face), the application memory is 128MB FLASH EPROM, which is used to store image programs, scripts, and tag databases. This memory is non removable system memory. In addition, the device provides 467mB of local storage space, which can be used to save historical data, alarm records, recipe parameters, or user files.

6.2 Backup Memory and Clock Battery

The backup memory uses NVRAM (non-volatile RAM) with a capacity of 500KB, which is used to maintain critical variables, recipe data, or system parameters that need to be retained after power failure. NVRAM can store data for a long time without the need for batteries. The clock data backup uses a user non replaceable primary lithium battery (main battery). This means that after the lifespan of the clock battery is over, the device needs to be returned to the factory for replacement or undergo a clock reset. When designing, it is necessary to consider the overall lifecycle of the equipment.

Interface and Communication Capability

7.1 USB interface

USB 2.0 Type A: 1, output voltage 5VDC ± 5%, maximum output current 500mA. Can be used to connect external devices such as USB flash drives (for program upload/download, data recording and export), mice, keyboards, or barcode scanners. Communication distance ≤ 5 meters.

USB 2.0 micro-B: 1, used for programming communication or file transfer with PC, with a distance of ≤ 5 meters.

7.2 Ethernet interface

The device is equipped with two RJ45 Ethernet ports, which comply with the IEEE802.3i/802.3u standard and support 10BASE-T and 100BASE-TX. The design of dual Ethernet ports is very practical: one can connect to the higher-level control network (such as communicating with PLC and SCADA systems), and the other can connect to on-site devices or achieve data sharing between screens; It can also be used to build network redundancy or as a switch (with software support). This provides a foundation for data collection and remote monitoring in the Industrial Internet of Things (IIoT).

7.3 Other communication protocols

Although the document does not list all supported fieldbuses in detail, as a Pro face STM6000 series, this model typically supports connecting mainstream PLC brands such as Siemens, Rockwell, Mitsubishi, Omron, etc. via Ethernet or serial port (please refer to the complete specification sheet). Specific protocol support should refer to the device list of official software (GP Pro EX or BLUE).
