5. รหัส HS (Reference for Customs Declaration in Foreign Trade)

ฮส: 8537101190, คอนโทรลเลอร์ลอจิกที่ตั้งโปรแกรมได้ (บมจ). For pre-declaration reference only, subject to actual customs verification.

6. การติดตั้ง & 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. การต่อสายดิน: Single-point earthing for rack and cable shield to avoid interference causing SF/BF alarms.
11. การแก้ไขปัญหาทั่วไป
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, ตัวต้านทานปลายสาย, 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. รูปร่าง: No burn marks on housing, no corrosion on backplane, intact DP/MPI port, clear laser engraved serial number.
18. การทดสอบการเปิดเครื่อง: Use known good MMC card. Check RUN lamp after power on. Read CPU model, firmware version and diagnostic buffer online via STEP7.
19. การทดสอบการสื่อสาร: Normal MPI communication. Fit terminating resistor on DP port and test DP bus communication.
20. การทดสอบไอ/โอ: 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.
22. สถานการณ์การใช้งานทั่วไป

เครื่องจักรบรรจุภัณฑ์, small conveyor lines, PID control for fans & ปั๊มน้ำ, auxiliary small metallurgy equipment, retrofitting of old production lines with distributed DP I/O, spare part replacement for existing S7-300 equipment.

6ES7313-6CF03-0AB0 (CPU313C-2 DP) Supported Programming Languages

Programming Platform: STEP7 V5.3 SP2 or above (TIA Portal does NOT support this old firmware CPU)

✅ Standard Built-in Languages (Available in basic STEP7)

1. หนุ่มน้อย (แผนภาพบันได): Widely adopted in China, relay-style graphical logic
2. FBD (แผนภาพบล็อกฟังก์ชัน): Graphical programming with block wiring
3. เอสทีแอล (Statement List): Assembly-style textual instructions with high execution efficiency

✅ Optional Extended Languages (Requires STEP7 Professional add-on package)

1. S7-SCL (Structured Control Language): Pascal-like high-level textual language for complex calculation and data processing
2. S7-GRAPH: แผนภูมิฟังก์ชันตามลำดับ (เอสเอฟซี), suitable for pipeline and sequential process control
3. S7-HiGraph: State machine graphical language for multi-state switching equipment (rarely used)

บันทึก: C language is not supported. SCL ≠ C; CFC is exclusive for S7-400 and unavailable for this CPU.

หมายเหตุเสริม

Multiple languages can be mixed within one project (เช่น. 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.
