    Why is the red I/O LED ON on a M241 controller?

    The red I/O LED indicates device errors on the serial line 1 or 2, SD card, cartridge, TM4 bus, TM3 bus.

    Only the fact that serial line 1 or 2 is not connected or the SD card is not present will turn that I/O LED ON but everything else may work correctly.

    To find out exactly why the LED is turned on, you can check the PLC_R structure in a Watch window, specifically PLC_R.i_lwSystemFault_1
