HS: 8537101190, وحدة تحكم منطقية قابلة للبرمجة (بلك). For pre-declaration reference only, subject to actual customs verification.

6. تثبيت & Configuration Guidelines
7. MMC card is mandatory. The CPU cannot start without MMC. Damaged program on MMC will prevent CPU from entering RUN state.
8. Both ends of DP bus shall be fitted with terminating resistors. Termination switch is located on CPU DP port.
9. Onboard DI/DO: Digital input supports source type. Each transistor output point rated 0.5A, group total current limited by ambient temperature. Freewheeling diode is recommended in parallel for inductive loads.
10. Earthing: Single-point earthing for rack and cable shield to avoid interference causing SF/BF alarms.
11. استكشاف الأخطاء وإصلاحها الشائعة
12. SF red light steady on: System fault. Priority check: damaged MMC / program error, mismatched hardware configuration, backplane bus fault.
13. BF light flashing: PROFIBUS DP bus fault. Inspect DP cable, terminating resistor, disconnected slave station or address conflict.
14. All LEDs flashing after power-up: MMC damaged / missing MMC / corrupted program on MMC. Perform MRES reset test and retry with new MMC.
15. No output from onboard I/O: Transistor output burnt due to overcurrent. The integrated I/O of this CPU cannot be repaired separately; only CPU replacement available.
16. Acceptance Inspection Points for Second-hand Units
17. مظهر: No burn marks on housing, no corrosion on backplane, intact DP/MPI port, clear laser engraved serial number.
18. اختبار التشغيل: Use known good MMC card. Check RUN lamp after power on. Read CPU model, firmware version and diagnostic buffer online via STEP7.
19. اختبار التواصل: Normal MPI communication. Fit terminating resistor on DP port and test DP bus communication.
20. I/O test: Force output signals and measure each 16DI/16DO channel with multimeter to verify no faulty points.
21. Backup: Read original project and back up programs inside MMC.

ملاحظات تكميلية

Multiple languages can be mixed within one project (على سبيل المثال. FB programmed in SCL, OB1 in LAD)

After program download to CPU, the CPU does not recognize source language type; only compiled machine code is executed.

Built-in high-speed counting, PWM and PID technology function blocks can be called directly via SFB/SFC system function blocks; no extra language required.
