Connect your sensors and input devices to the 14 Digital Input (DI) terminals and your actuators and output devices to the 10 Digital Output (DO) transistor terminals. Pay close attention to polarity for DC circuits and ensure proper current ratings are observed for all connected devices.

3.3. Viestintäportit

• COM 1 (RS-232): Used for connecting to a host machine or Human Machine Interface (HMI) for programming, debugging, and data exchange.
• COM 2 (RS-485/RS-232): Supports network communication or connection to intelligent instruments, inverters, and other industrial devices.
• COM 3 (BD Extensional Communication Port RS-232/RS485): An additional port for extending communication capabilities.

3.4. Fyysinen asennus

The PLC can be installed using M3 screws for fixed mounting or by utilizing a DIN46277 (35mm width) guide rail. Ensure the installation location is stable, well-ventilated, and free from excessive vibration or electromagnetic interference.

3.5. Maadoitus

Proper grounding is crucial for the safe and reliable operation of the PLC. Implement the third type of grounding. Never perform common grounding with a strong power system to prevent electrical hazards and interference.

4. Käyttöohjeet

4.1. PLC:n ohjelmointi

The XC3-24T-E supports programming in both instruction list and ladder diagram modes. User programs have a capacity of 8000 steps. Programming is typically performed via the COM 1 (RS-232) port using compatible PLC programming software on a host machine.

4.2. Program Operation Modes

The PLC operates in two primary program modes:

• Circulation Scanning Mode: The PLC continuously scans and executes the user program from start to finish.
• Timing Scanning Mode: Program execution is synchronized with specific time intervals.

The dispose speed for program execution is approximately 0.5 microseconds, ensuring rapid response times for control applications.

4.3. Data Retention

The PLC utilizes FlashROM for power failure holding, meaning user programs and critical data are retained even if power is lost, ensuring system integrity and minimizing downtime.

4.4. Timers and Counters

The PLC includes a comprehensive set of timers and counters for precise control:

• Timers (T): 620 points available.
  • 100 ms ajastin: Aseta aika 0.1–3276.7 sekuntia
  • 10 ms ajastin: Aseta aika 0.01–327.67 sekuntia
  • 1 ms ajastin: Aseta aika 0.001–32.767 sekuntia
• Counters (C): 635 points available.
  • 16-bittinen laskuri: Aseta arvo K0~32767
  • 32-bittinen laskuri: Aseta arvo K0~2147483647

Data Registers (D) provide 8512 characters for storing operational data.

5. Huolto

To ensure the longevity and reliable operation of your XINJE XC3-24T-E PLC, adhere to the following maintenance guidelines:

• Ympäristöolosuhteet: The PLC is designed to operate within an environment temperature range of 0°C to 6°C and an ambient humidity of 5% to 95% (non-condensing). Operating outside these ranges may affect performance and lifespan.
• Puhdistus: Regularly clean the exterior of the PLC with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure ventilation openings are free from dust and debris to prevent overheating.
• Yhteyden tarkistukset: Periodically inspect all wiring connections to ensure they are secure and free from corrosion. Loose connections can lead to intermittent operation or system failures.
• Laiteohjelmistopäivitykset: Tarkista valmistajalta website for any available firmware updates that may improve performance or address known issues. Follow update procedures carefully.
• Virtalähteen vakaus: Ensure a stable and clean power supply. Fluctuations or noise in the power supply can impact PLC operation.

6. Vianmääritys

This section provides general guidance for common issues. For complex problems, consult the XINJE technical support or a qualified technician.

6.1. Merkkivalot

Observe the status indicator lights on the PLC front panel:

• PWR (teho): Should be steadily lit when power is supplied correctly. If off, check power connections and source.
• JUOSTA: Indicates the PLC is in run mode and executing the program. If off or blinking, the PLC may be in stop mode or encountering an issue.
• ERR (Virhe): If lit, an internal error or program error has occurred. Refer to the programming software for detailed error codes and diagnostics.

6.2. Yleisiä ongelmia

• PLC Not Powering On: Tarkista virtalähteen tilavuustage matches the PLC's requirements (AC220V or DC24V). Check all power wiring for secure connections and continuity.
• Inputs Not Responding: Check wiring to input devices. Ensure sensors are correctly powered and functioning. Verify input addresses in the PLC program match physical connections.
• Lähdöt eivät aktivoidu: Check wiring to output devices. Ensure actuators are correctly powered and functioning. Verify output addresses and logic in the PLC program. Check for overload or short circuits on output terminals.
• Viestintäongelmat: Verify cable connections (RS-232/RS-485). Ensure communication parameters (baud rate, data bits, parity, stop bits) are correctly configured in both the PLC and the connected device (e.g., HMI, PC).
• Ohjelmavirheet: If the ERR light is on, connect to the PLC with programming software to identify the specific error. Common errors include syntax errors, logic faults, or memory issues.
