Flashing Pause LED on Nano-10

[msi124]

The Pause LED is flashing after power-on and I am unable to communicate with the PLC by either RS485 or ethernet.  I have jumped #4 and still get the flashing red LED and am still unable to communicate via RS485.  Suggestions?

If DIP switch #4 is ON then the PAUSE LED should stay ON and should not be flashing. If PAUSE LED keeps flashing then it looks like the PLC is being rebooted consecutively and could be a problem with the power supply.

What type of power supply? How many volts and how much current can it supply.

Try changing the power supply if you have a different power supply unit.
