Installation & Operation FAQ
Ethernet connection fails during setup - device cannot communicate with HMI or upper computer
Verify Ethernet cable type (XDQ3E supports auto MDI-X), confirm IP addresses are in same subnet, check router/switch ports, and ensure firewall isn't blocking communication ports.
Controller restarts intermittently after powering on overseas
Typically caused by unstable voltage beyond DC24V±10% range. Install voltage stabilizer or UPS, and check for loose wiring connections.
Program downloads successfully but some I/O points don't respond during operation
Verify I/O point definitions match hardware model, check wiring configuration (NPN vs PNP), and use XDPPro diagnostic function to test I/O points.
Controller malfunctions in high humidity or dusty workshop environments
IP20 rating requires installation in sealed electrical cabinet with dehumidifier or dust filter. Avoid mounting near heat-generating equipment.
Local inspection failure due to wiring not meeting safety standards in Europe
Use shielded communication cables with proper grounding, adequate power cable cross-sections, and install required residual current device (RCD).
Remote debugging needed when local technicians are unavailable overseas
Connect controller to internet router, set up port forwarding or VPN, and use XDPPro remote access function for secure connection.
