    • L
      Lorraine ColemanAug 8, 2025
      The "AS EXCH" LED is off because there is no data exchange with the master. To resolve this, activate the cyclic data transfer with the master and check the master and bus connection to the CPU.

    How to fix Stahl Computer Hardware when "M/S" LED is flashing?
    • A
      Amy KaufmanAug 26, 2025
      If the "M/S" LED is flashing, it could be due to: * Ambient temperature being outside the specification * The firmware versions of redundant CPUs being different. Reduce the ambient temperature, for example, by means of shading or cooling. Note: If the problem is not eliminated, the module will be permanently damaged. Also, carry out a firmware update.

    • J
      Jessica MejiaAug 30, 2025
      When the "M/S" LED is lit, it means the module is damaged due to excessive temperature or the end of its service life has been reached. Replace the module as soon as possible (within the next 12 months), otherwise there is a risk of module failure.

    • M
      Matthew LewisSep 3, 2025
      If the "PWR" LED is off, it indicates that the power supply to the CPU module is interrupted. Check that the connection is correct and the power module is intact. Check that the base is intact. Check that the CPU module is mounted correctly on the base. If necessary, replace the CPU module.
