3. Operasie
3.1 Basiese Funksies
The OP320-A allows operators to monitor and modify PLC data. The display shows text or indicators representing PLC internal registers or relay statuses.
Figuur 3.1.1: Voorkant view of the OP320-A HMI Text Display. The screen displays 'Welcome to JingBiao Automation'. The keypad includes numeric buttons (0-9), +/-/CLR, ESC, ALM, arrow keys, SET, and ENT buttons.
3.2 Keyboard Input
The display features a numeric keypad and function buttons for data entry and navigation.
- Numeriese sleutelbord (0-9): For entering numerical values.
- +/-/CLR: Used for sign changes or clearing input.
- ESC: Escape or cancel function.
- ALM: Access alarm information.
- Pyltjiesleutels (Op, Af, Links, Regs): For navigation within menus or data fields.
- STEL: Enter setup or configuration modes.
- INT: Confirm or enter selection.
The 20 self-defined function buttons can be programmed for specific tasks within your application.
3.3 Sagtewarekonfigurasie
The OP320-A is configured using the TP200CN editing software on a computer. This software allows you to:
- Create and edit display screens.
- Define PLC addresses for monitoring and control.
- Download screen data and communication protocols to the display via serial communication.
No PLC communication program is required for the display to function once configured.
3.4 Alarm Funksie
The display includes an alarm list function. When an alarm condition is met in the PLC, the display can show real-time alarm information by line. Access to certain functions or configurations may be protected by a password.
4. Onderhoud
4.1 Skoonmaak
To clean the display, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth with a mild, non-abrasive cleaner can be used. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the screen or casing.
4.2 Omgewingstoestande
Ensure the display operates within the specified environmental conditions to maintain optimal performance and longevity.
- Werkstemperatuur: 0 ~ 50 ℃ (32 ~ 122 ℉)
- Werkomgewing Humiditeit: 20 ~ 90% RH (nie-kondenserend)
- Bergingstemperatuur: -20 ~ 70 ℃ (-4 ~ 158 ℉)
The device has an IP65 grade, indicating protection against dust and low-pressure water jets from any direction. However, avoid prolonged exposure to extreme conditions.
5. Probleemoplossing
5.1 Algemene kwessies
- Skerm skakel nie aan nie:
- Check the power supply connection and ensure it is within the 12-24V range.
- Verifieer dat die kragbron aktief is.
- No Communication with PLC:
- Ensure the communication cable is correctly connected to both the HMI and the PLC.
- Verify that the communication settings (baud rate, data bits, parity, stop bits) in the HMI and PLC match.
- Check the wiring for RS232 or RS485 for proper pin assignments.
- Confirm that the PLC is powered on and functioning correctly.
- Incorrect Data Displayed:
- Review the PLC address settings in the HMI configuration software (TP200CN) to ensure they correspond to the actual PLC registers.
- Verify the data format and scaling settings.
- Skerm reageer nie:
- Herbegin die HMI deur dit weer aan te skakel.
- If the issue persists, re-download the HMI configuration using TP200CN.
