Frequently Asked Questions
Q1: Screen is black and no power on?
Check 24VDC power connection first, replace damaged adapter if voltage is abnormal; re-download the program if power is normal but still black.
Q2: No communication with PLC, data not updated?
Verify cable connection (RJ45/RS485) and port indicator; match HMI & PLC protocol, baud rate and address in software; replace faulty communication cable/port.
Q3: Touch screen unresponsive or slow?
Run HMI self-test first, recalibrate touch screen if test fails; optimize communication speed or split program variables if response is slow.
Q4: Screen displays garbled code?
Adjust HMI data range if over-limit; use shielded cable and single-end grounding to avoid EMI; match data format with PLC.
Q5: HMI freezes or restarts frequently?
Check if working temp exceeds 0–50℃, keep away from heat source; close redundant background programs; replace unstable power supply if voltage fluctuates.
Q6: Installation fails with loose fixation?
Use the original spring clip for tool-free mounting, ensure the panel is tightly fixed on the OEM equipment cabinet.
Q7: USB/RJ45 port not working?
Check if the port is physically damaged; replace the peripheral device for testing; re-set the port parameter in the software.
