3.1 Индикатор жарыктары
The front panel features several indicator lights:
- ЖҮГҮРҮҮ: Illuminates when the processor is in Run mode and executing the user program.
- FLT (Fault): Illuminates when a major fault occurs. Refer to the troubleshooting section for details.
- BATT (Battery): Батарея кубаты толгондо күйөтtage is low, indicating a need for replacement.
- КҮЧ: Illuminates when an I/O point is being forced.
- DH+: Indicates activity on the Data Highway Plus communication port.
- 232: Indicates activity on the RS232 communication port.
3.2 Key Switch Positions
The key switch on the front panel controls the processor's operating mode:
- ЖҮГҮРҮҮ: The processor executes the user program. No program changes can be made.
- REM (Алыстан): The processor mode can be changed via programming software (e.g., RSLogix 500).
- PROG (Программа): The processor is in Program mode, allowing program upload, download, and modifications. The processor does not execute the user program in this mode.
4. Техникалык тейлөө
4.1 Батареяны алмаштыруу
When the BATT indicator illuminates, the processor's battery needs replacement to retain memory during power loss. Power down the chassis, carefully remove the processor, and replace the battery according to the instructions in the full SLC500 hardware manual. Use only approved replacement batteries.
4.2 Тазалоо
Periodically inspect the processor and chassis for dust and debris. Use a soft, dry cloth or compressed air to clean the unit. Ensure power is disconnected before cleaning.
5. Кыйынчылыктарды
5.1 FLT Indicator
If the FLT indicator is illuminated, a major fault has occurred. Common causes include:
- Programming errors.
- Hardware failures in I/O modules.
- Communication errors.
To diagnose, connect to the processor with programming software (e.g., RSLogix 500) and check the fault status. Clear the fault after resolving the issue.
5.2 Processor Not Responding
If the processor is unresponsive, check the following:
- Ensure the chassis has power.
- Verify the key switch position is appropriate for the desired operation.
- Check communication cables and settings.
