    The computer hard disk of the Mark V HMI is damaged, but the hard disk was not backed up beforehand. How can I recover the program?

    If possible, swap cables with another known working HMI to rule out cable or port failure.

    UNWANTED TRIPPING OF ANTI-SURGE VALVES

    Fast-acting control valves are critical. Industry preference is for high-performance globe valves or butterfly valves with low dead time and hysteresis. Use smart positioners (e.g., Fisher DVC6200, Siemens SIPART, ABB TZIDC) with diagnostics. Avoid valves with long stroke travel or large...

    Wanted - multi NTC sensor/simulator.

    If you're okay with a bit of assembly but not building from scratch, you can use an ESP32 or a Raspberry Pi Pico + Analog Switches + DACs. Use analog switches (e.g., ADG733) to switch between real sensors and DAC (simulated value). You have to write the script in MicroPython or Arduino.

    MTL 5082

    None of the modules you listed are direct replacements for the MTL5082, which is a specialized resistance signal isolator designed to interface directly with 2-, 3-, or 4-wire RTDs (e.g., Pt100) in hazardous areas. Most of your listed modules, such as the MTL7056, MTL7055, MTL7028, and MTL7265...

    Do I need CSA certification for a vending machine imported from China to Canada

    CSA Group (Canadian Standards Association) is the most commonly accepted certifying body. If your vending machine is factory-certified by CSA, you can import and use it with fewer regulatory headaches.

    Alarm Report (Alarm Buffer) Printing Blank in WinCC Runtime Advanced

    Temporarily remove the Date/Time filter tags and regenerate the report to check if any data appears. If it works without filtering, the problem lies in the tag values or format.

    Graphics during runtime different from design stage

    Set a Fixed Screen Resolution, Check Anchoring Settings , Use Grouping and Alignment. In HMI Runtime Settings, under Screen settings, make sure "Adapt screen to resolution" or "Fit to screen" is turned off or set to match native resolution. If you're simulating on a PC, make sure your runtime...

    Data exchange between 2 Delta PLC's DVP-12SE

    If you're committed to Modbus TCP, use industrial wireless Ethernet bridge radios like Ubiquiti NanoStation, MikroTik, Phoenix Contact or Hirschmann wireless bridges (industrial-grade). They behave like Ethernet cables, not serial lines, and maintain TCP/IP integrity and low latency.

    Centum CS 3000 R5.02 - HIS Failure

    The error messages you're seeing: 10060 (Winsock Error) – This is a standard TCP connection timeout, indicating that the HIS tried to connect to a service (likely the LDS or FCS or LdXops server) and got no response within the timeout window. 7002 – Often indicates communication failure during...
